2020 Washington Nationals season

The 2020 Washington Nationals season was the Nationals' 16th season as the baseball franchise of Major League Baseball in the District of Columbia, the 13th season at Nationals Park, and the 52nd since the original team was started in Montreal, Quebec, Canada. The team entered this season as the defending World Series champions.
On March 12, 2020, MLB announced that because of the ongoing COVID-19 pandemic, the start of the regular season would be delayed by at least two weeks in addition to the remainder of spring training being cancelled. Four days later, it was announced that the start of the season would be pushed back indefinitely due to the recommendation made by the CDC to restrict events of more than 50 people for eight weeks. On June 23, commissioner Rob Manfred unilaterally implemented a 60-game season. Players reported to training camps on July 1 in order to resume spring training and prepare for a July 23 Opening Day. On September 19, the team suffered its 31st loss, assuring them of finishing the season with a losing record, their first since 2011. On September 22 in game 2 of a doubleheader, the Nationals would get their 4,000th regular season win in franchise history on a walk-off home run by Yadiel Hernández to beat the Phillies 8–7. On September 24, the Nationals were eliminated from playoff contention, making them the 20th defending champion unable to repeat back to back titles. The Nationals finished the regular season with a record of 26–34, giving them a 4th-place finish in the NL East as a result of the Nationals' 6–4 head-to-head against the Mets, who also finished 26–34 (.433). The Nationals's .433 winning percentage was the lowest for a defending champion since the 1998 Florida Marlins went 54-108 (.333).
Offseason.
Team news.
The day after the Washington Nationals won the 2019 World Series on October 30, 2019, in Houston, Texas, nine members of that championship team officially filed for free agency: pitchers Jeremy Hellickson, Daniel Hudson, Fernando Rodney, and Jonny Venters; infielders Asdrúbal Cabrera, Brian Dozier, Howie Kendrick, and Anthony Rendon; and outfielder Gerardo Parra. On November 1, the Nationals announced they would not exercise their share of the 2020 mutual option for first baseman Matt Adams, making Adams a free agent as well. The Nationals also declined club options over first baseman Ryan Zimmerman and catcher Yan Gomes, who also became free agents, on November 2. They exercised club options to keep pitcher Sean Doolittle and outfielder Adam Eaton under contract for the 2020 season. Hellickson chose to retire instead of pursuing another career opportunity, citing a nagging shoulder injury.
Considerable media speculation swirled around whether the Nationals would re-sign Rendon, who was a finalist in National League Most Valuable Player balloting, and Strasburg, who was the World Series MVP. Washington general manager Mike Rizzo expressed public interest in bringing back both players, who rejected one-year qualifying offers from the Nationals. However, in an early-December interview with Donald Dell, Nationals principal owner Mark Lerner said the club "can only afford to have one of those two guys", downplaying the possibility that both could fit into Washington's 2020 payroll. On December 9, 2019, at the annual winter meetings in Strasburg's hometown of San Diego, the Nationals announced they had come to terms with Strasburg on a new, seven-year pact, reported to be worth $245 million, a record for a free agent pitcher. At the press conference making the announcement, Rizzo also confirmed that the Nationals had re-signed Kendrick to what was reported as a one-year major league deal. Kendrick's signing was officially announced the following day, along with the re-signing of Gomes to a two-year deal. The team also re-signed Zimmerman and Cabrera to one-year major league deals and brought back Hudson on a two-year guarantee. Rendon ultimately signed with the Los Angeles Angels on a seven-year deal.
The Nationals were also linked in media reports to other free agents, including first baseman Justin Smoak (ultimately signed by the Milwaukee Brewers), third basemen Josh Donaldson (ultimately signed by the Minnesota Twins) and Maikel Franco (ultimately signed by the Kansas City Royals), along with starting pitchers Madison Bumgarner (ultimately signed by the Arizona Diamondbacks) and Zack Wheeler (ultimately signed by the Philadelphia Phillies).
Eight Nationals were eligible for salary raises through the arbitration system during the offseason: pitchers Roenis Elías, Koda Glover, Javy Guerra, Joe Ross, and Hunter Strickland; infielders Wilmer Difo and Trea Turner; and outfielder Michael A. Taylor. The Nationals signed Strickland and Difo to new one-year contracts. Hours before the deadline for teams to tender new contracts to arbitration-eligible players, on December 2, Glover announced his retirement from professional baseball at age 26. The Nationals tendered contracts to all eligible players except Glover and Guerra, who were non-tendered, although Guerra later re-signed with the Nationals on a minor league pact. The Nationals agreed to one-year contracts for each of their tendered players, avoiding arbitration.
Within days, the Nationals signed a new reliever, former Oakland Athletics minor league closer Kyle Finnegan. Finnegan was the first free agent signing of the offseason announced by the team, on December 8, 2019. The Nationals added to their bullpen again on January 3, 2020, announcing they had signed veteran Will Harris to a three-year contract. On January 29, the team acquired reliever Ryne Harper from the Minnesota Twins.
The Nationals added new blood to their position player roster as well, announcing the signings of infielders Starlin Castro to a two-year deal and Eric Thames to a one-year deal on January 7 and January 8, respectively.
Spring training.
The Nationals held spring training at their facility at FITTEAM Ballpark of the Palm Beaches in West Palm Beach, Florida, which they share with the Houston Astros. It was their fourth year at the facility.
On February 12, the Nationals announced they had invited the following players on minor league contracts to participate in major league spring training: left-handed pitchers Fernando Abad and Sam Freeman; right-handed pitchers Dakota Bacus, Bryan Bonnell, Wil Crowe, Paolo Espino, Jhonatan Germán, Javy Guerra, David Hernandez, Kevin Quackenbush, and Derek Self; catchers Welington Castillo, Taylor Gushue, and Jakson Reetz; infielders Luis García, Drew Ward, and Jacob Wilson; outfielders Yadiel Hernández and Mac Williamson; infielder/outfielders Emilio Bonifácio and Brandon Snyder; and outfielder/left-handed pitcher J. B. Shuck.
On March 12, the remainder of spring training was cancelled due to the coronavirus pandemic. The Nationals had a record of 6–11–2 before this happened. When the new schedule was announced for the 2020 season, it included three new exhibition games against the Phillies and Orioles, which count as Spring Training games.
Regular season.
Opening Day.
The Nationals' season started out in unceremonious fashion: Juan Soto, their starting left fielder and co-recipient of the 2019 Babe Ruth Award, tested positive for COVID-19 and was placed on the injured list hours before first pitch on Opening Day on July 23 versus the New York Yankees. Despite testing negative on follow-up rapid testing, Soto was unable to participate in baseball activities due to MLB and District of Columbia health protocols.
The first game of the season was itself frustrating for the Nationals, who were held to one run—a solo home run from right fielder Adam Eaton—by Yankees ace Gerrit Cole, whom they had beaten twice during the 2019 World Series, before heavy rains forced the game to be called midway through the sixth inning. Nationals starter Max Scherzer was shaky and gave up all four of New York's runs in the loss, three of them batted in by Yankees slugger Giancarlo Stanton, a frequent bugbear of the Washington ace.

Juan Soto tested positive for COVID-19 and thus was placed on the IL.
July.
After dropping their first game of the season and losing outfielder Juan Soto to the injured list with a positive COVID-19 test, the Nationals' woes continued as ace Stephen Strasburg, the reigning World Series MVP, was scratched from his first start on July 25 with a nerve issue in his throwing hand. Erick Fedde stepped in as the July 25 starter versus the New York Yankees, contributing four innings in a 9–2 victory for Washington. The Nationals knocked out Yankees starter James Paxton in the second inning. Center fielder Víctor Robles had three hits, including a two-run double off Paxton and a two-run home run off the left field foul pole against reliever Mike King. Tanner Rainey picked up the win in relief with a scoreless inning. Kyle Finnegan made his major league debut with a scoreless ninth inning for the Nationals. Despite an outstanding 6⅓ innings of work from starter Patrick Corbin in the rubber game on July 26, the Nationals didn't get much offense going against the Yankees despite an early home run off Jonathan Loaisiga from shortstop Trea Turner. After Corbin allowed a seventh-inning home run to Gleyber Torres, his only run given up and just his second baserunner allowed, manager Davey Martinez hooked him in favor of Will Harris, making his Nationals debut after signing a three-year contract early in the offseason. Harris gave up a game-tying solo home run by Luke Voit. Nationals reliever Sean Doolittle took the loss as Torres knocked in another run on a single in the eighth inning and Zack Britton shut the door for New York.
On July 27, the Nationals signed utilityman Josh Harrison to a one-year deal and added him directly to the major league roster, optioning extra catcher Raudy Read to the alternate training site in Fredericksburg, Virginia. Nationals starter Aníbal Sánchez surrendered four solo home runs over five innings, taking the 4–1 loss, as the Nationals opened an interleague series against the Toronto Blue Jays later that day. With former National Tanner Roark starting for the Blue Jays in the second game of the home-and-home series, the Nationals again managed to scratch out just one run, with second baseman Starlin Castro committing two fielding errors that contributed to three unearned runs of five scored by the Blue Jays in the game. Washington's starter, Austin Voth, gave up two earned runs over five innings for the loss. With Canadian coronavirus protocols preventing the Blue Jays from playing home games in Toronto and improvements to Sahlen Field, their temporary home in Buffalo, New York, still under construction, Nationals Park hosted the Blue Jays as the "home team" for the next two games. The first of the two, July 29, was also the first test for the Nationals of a rule adopted for the 2020 season under which a baserunner starts each half-inning of extra innings on second base. Neither team managed to score over the first nine innings behind excellent starts for the Nationals' Max Scherzer and Blue Jays rookie Nate Pearson, sending the game into extra innings. Right fielder Adam Eaton finally broke the tie for the Nationals in the tenth inning with a two-out infield single that scored automatic runner Emilio Bonifácio. The Nationals went on to win 4–0, with third baseman Asdrúbal Cabrera tripling home three more runs that inning before Rainey dispatched the "home" team in the bottom of the tenth. The Nationals won again on July 30, also as the "away" team in their own ballpark, as Castro went 4-for-5 and left fielder Michael A. Taylor hit a two-run homer off Toronto starter Hyun-jin Ryu in the 6–4 contest. Fedde started again in place of Strasburg, but it was reliever Ryne Harper who earned the win, his first as a National, as Fedde was pulled in the fourth inning after giving up two runs. Nationals closer Daniel Hudson locked down his first save of the campaign.
The Nationals were set to have their first roadtrip of the season starting July 31, visiting the division-rival Miami Marlins, but the series was postponed after several Marlins players and personnel tested positive for COVID-19. They finished July with a 3–4 record, third in the National League East Division.
August.
After opening August with three straight days off due to the Miami Marlins' positive COVID-19 tests and a scheduled off day, the Nationals returned to action with a 5–3 win over the division-rival New York Mets at Nationals Park on August 4. Star left fielder Juan Soto was activated after missing time following his own positive COVID-19 test, although he did not play in the August 4 game. The Nationals also activated reliever Wander Suero after placing Harris on the injured list with a right flexor strain. Outfielder Andrew Stevenson was optioned to the alternate training site. In the August 4 game, first baseman Howie Kendrick went 4-for-4, beginning with a first-inning home run off Mets starter Steven Matz that Soto celebrated by dancing on top of the home dugout. Left fielder Josh Harrison recorded his first hit of the season with a second-inning home run off Matz. Starting pitcher Patrick Corbin got the win despite allowing three runs over 5⅔ innings. After their raucous return to action, however, the Nationals' bats fell silent. Behind Rick Porcello, the Mets pulled out a series split by winning 3–1 on August 5. Max Scherzer started the game for the Nationals but exited with a hamstring issue after just one inning of work, replaced by Erick Fedde, who went on to take the loss in relief. Making his season debut, Soto drove in the Nationals' only run of the game with an RBI double off Porcello.
Rosters contracted to 28 players on August 6 after starting the season at 30 players, and the Nationals chose to option reliever James Bourque and designate utilityman Emilio Bonifácio for assignment to trim their roster down to size. After another off day, the Nationals lost two games to their interleague rivals, the Baltimore Orioles, including an 11–0 drubbing in which former National Tommy Milone earned the win as the Orioles' starter on August 7. The Nationals led 3–0 into the eighth inning on August 8, but Sean Doolittle gave up back-to-back home runs to trim Baltimore's deficit before closer Daniel Hudson allowed a three-run home run by Anthony Santander for the blown save and loss. In Stephen Strasburg's season debut for the final game of the three-game set on August 9, the Nationals' struggles manifested themselves in a new way, as the game was postponed in the sixth inning when the Nationals Park grounds crew was unable to unroll the tarp over the infield in time for heavy rains to render the field unplayable for the rest of the night.
The Nationals rebounded from three straight losses with a 16–4 drubbing of the Mets on August 10, as first baseman Asdrúbal Cabrera went 4-for-4 with two home runs against his former team and Soto clubbed a home run beyond the apple sculpture in straightaway center at Citi Field, the longest of his career. Corbin earned the win, giving up two runs in six innings. The Nationals followed that rout up with another win on August 11, as Scherzer and the Nationals avenged their earlier defeat by Porcello and the Mets. Shortstop Trea Turner opened the game for the Nationals with a home run off Porcello, who took the loss, while Scherzer earned the win with six strong innings in the 2–1 contest. The Mets rallied, however, to split the four-game series by winning the next two games. In the August 12 game, they overcame two more Soto home runs, including a -blast that landed in the vacant concessions area high in the right field stands, by scoring five early to chase Nationals starter Aníbal Sánchez in the third inning and then thumping reliever Ryne Harper for five more in the sixth inning. The Nationals had to take two players out of the game: starting center fielder Víctor Robles, who was hit on the hand by a pitch, and left-handed reliever Sam Freeman, who suffered an elbow injury. Before the August 13 game, the Nationals moved both Freeman and Doolittle, dealing with a right knee issue, to the injured list. They selected the contract of left-hander Seth Romero, one of their top pitching prospects, and activated Harris to fill the blank spots in the bullpen. The Mets won 8–2, getting to Nationals starter Austin Voth early and forcing manager Davey Martinez to go to his bullpen starting in the fifth inning. Voth took the loss, but much of the damage was allowed by Romero, making his major league debut in relief, as New York catcher Tomás Nido hit a two-out grand slam to center to blow the game open. Soto hit his fourth home run of the series in the sixth inning, but the damage was done and the Mets cruised to a win.
In another unusual quirk of the season's modified rules, when the Nationals resumed the interrupted August 9 game against the Orioles on August 14, they did so as the "home" team at Oriole Park at Camden Yards, proceeding to a loss. Reliever Dakota Bacus, called up to give the Nationals a fresh bullpen arm while Harper was optioned, made his debut in the continued game with two shutout innings. While the 6–2 finish marked the second time of the month the Nationals had lost three games in a row, they suffered a more significant loss as second baseman Starlin Castro dove for a ball and broke his wrist, sending him to the injured list for the remainder of the season. To replace Castro on the roster and as the team's starting second baseman, the Nationals called up top prospect Luis García from the alternate training site, selecting his contract for a major league debut in that evening's game, played as a regular home game for the Orioles. Both García and fellow rookie infielder Carter Kieboom starred in the 15–3 win, with García singling off Baltimore's starter Milone in the third inning for his first career hit and later doubling in Soto and Cabrera for his first RBIs while Kieboom, the starting third baseman in the game, flashed the leather with 10 assists, many of them while playing in a defensive shift, to set a new team record for assists by a third baseman. Unfortunately for the Nationals, however, their starting pitcher Strasburg exited the game after giving up a Santander home run and recording just two outs. Strasburg was later moved to the injured list and ultimately shut down for the season with carpal tunnel neuritis in his throwing hand, with Harper recalled to take his place on the roster. The Nationals and Orioles split the next two games at Oriole Park at Camden Yards, with Corbin suffering his first loss of the season on August 15 as he allowed five runs over five innings before the Nationals rebounded to gut out a 6–5 win behind Scherzer in the series finale the next day. Scherzer got the win despite allowing five runs over seven innings, with two solo home runs by Santander and a three-run home run by Scherzer's former catcher and Nationals teammate, Pedro Severino, as Soto scored on a fielding error in the eighth inning.
Another scheduled three-game series was shortened to two games by rain, but not before the Nationals split the first two with the division-rival Atlanta Braves. The Braves pinned another blown save and loss on Hudson, struggling in his role as Washington's closer, with a walkoff home run by Dansby Swanson capping a four-run rally in the ninth inning of the August 17 game, with a final score of 7–6. The meltdown eclipsed García's first career home run in the game, as he became the first player born in the 2000s to hit a major league home run, with a two-run shot in the second inning off Touki Toussaint. Hudson rallied from the loss to lock down the save and complete a 8–5 win for the Nationals on August 18, credited to Suero in relief after Voth was tagged for five runs over four innings. Romero, Bacus, Harris, Javy Guerra, and Kyle Finnegan also provided scoreless relief appearances in the game. The August 19 game was postponed by rain.
Finally playing the rival Marlins after an earlier series was postponed by COVID-19, the Nationals lost three of five at Nationals Park, including a makeup "away" game played as part of an August 22 doubleheader. Returning after his recovery from COVID-19, shortstop Miguel Rojas did all of the damage for the Marlins in a 3–2 Nationals loss on August 21, sending a three-run homer to left field off Corbin in the second inning. The Nationals split the doubleheader on August 22, winning as the home team in the matinee—while Scherzer struggled and departed in the fifth inning with the bases loaded, Finnegan struck out catcher Jorge Alfaro to stifle the threat and earned his first career win—and losing in the nightcap, as prospect Wil Crowe, selected from the alternate training site to start the game for the Nationals, was hooked in the fourth inning and ultimately tagged for four runs as the reliever Romero let in two inherited runners. Making his own major league debut, opposing starter Sixto Sánchez gave up three runs over five innings, on home runs by Nationals catcher Yan Gomes and center fielder Robles, but earned the win. Aníbal Sánchez finally earned his first win of the season on August 23, giving up just one run over seven innings. Miami turned to right-hander Sterling Sharp, a Nationals prospect whom the Marlins had claimed in the 2019 Rule 5 draft, in relief after starter Humberto Mejía was chased in the fourth inning. The Nationals hit Sharp hard in the fifth inning, scoring five runs off him. The Marlins designated Sharp for assignment after the game and returned him to the Nationals. Washington made its own roster move in the bullpen on August 24, with Romero out for the season after breaking his right hand in a fall on the stairs, according to manager Davey Martinez; he was placed on the injured list and fellow southpaw Ben Braymer was called up from the alternate training site. The Marlins took the rubber game that evening, with Voth again being pummeled to the tune of seven runs allowed over 3⅔ innings. The Nationals mounted a comeback but couldn't complete it, with the Marlins winning 11–8 despite a 4-for-5 effort from Soto and four RBIs by Eaton.
For their third three-game losing streak of August, as well as their third scheduled three-game series of August truncated to two, the Nationals dropped games on August 25 and August 26 to the division-rival Philadelphia Phillies before the August 27 game was postponed. Fedde was battered in the series opener, which the Nationals lost 8–3 after a lengthy rain delay, despite another leadoff home run by Turner. It was the bullpen that scuffled to the loss on August 26. Although bolstered before the game by the return of Doolittle, activated to take the place of third baseman Carter Kieboom as the offensively challenged Kieboom was optioned to the alternate training site, the relief corps couldn't withstand a Phillies rally as Harris gave up the tying and go-ahead runs in the seventh inning, not helped by an outfield collision between Robles and Eaton. The scheduled August 27 game was postponed, as players from the Phillies and the Nationals boycotted due to the shooting of Jacob Blake in Kenosha, Wisconsin, earlier that week.
On a roadtrip to Fenway Park to play an interleague series with the Boston Red Sox, the Nationals started off with an easy 10–2 win behind Scherzer on August 28. Braymer made his major league debut in relief, giving up one run over two innings before being optioned back to the alternate training site after the Nationals signed former longtime Red Sox utilityman Brock Holt to a major league deal on August 29. But Washington finished out the month on yet another three-game skid, as the Red Sox took the next two games by handing still more losses to Sánchez and Voth, and Fedde was greeted in Philadelphia on August 31 with six runs allowed over six innings for another loss.
Overall, the Nationals went 9–16 in August and finished the month in last place in the National League East Division.
September.
September started in disastrous fashion for the Nationals, whose losing streak extended to seven games as they were swept by the division-rival Philadelphia Phillies and dropped their first of four games against the rival Atlanta Braves. Compounding their frustration, they were shut out by the Phillies on September 1 and September 2 before pushing the September 3 game to extra innings before losing 6–5 in the tenth. The Nationals never got anything going against Phillies ace Aaron Nola on September 1, whereas Patrick Corbin's midseason woes continued as he lost the 6–0 shutout. After Nola threw eight innings and held Nationals stars Trea Turner and Juan Soto hitless, Nationals manager Davey Martinez admitted it was the best performance he had yet seen from Nola. It was Max Scherzer's turn on September 2, with Zack Wheeler leading the Phillies' 3–0 shutout of the Nationals. Scherzer allowed three runs over six innings for the loss, receiving no run support. To add injury to insult, Nationals reliever Javy Guerra suffered a hamstring injury in relief of Corbin and landed on the injured list the next day, with the Nationals recalling Kyle McGowin to replace him in the bullpen. While the Nationals broke out of their scoreless slump on September 3, aided by an inside-the-park home run by Turner and an over-the-fence home run by Michael A. Taylor, reliever Daniel Hudson blew the save in the eighth inning and Sean Doolittle took the loss as the Phillies cashed in their automatic runner in the bottom of the tenth.
The Nationals lost the first game in a doubleheader at Truist Park in Atlanta on September 4, as the bats again went quiet and fifth starter Austin Voth again imploded, giving up five runs, including two home runs by Ronald Acuña Jr., in 4⅔ innings en route to a 7–1 loss. To make matters worse, the Nationals scratched Soto with elbow soreness and sat fellow outfielder Adam Eaton with a knee injury he had suffered the previous night. While still missing their usual corner outfielders, and turning again to rookie starting pitcher Wil Crowe for the spot start in the nightcap, the Nationals pulled out a 10–9 win. Crowe was lifted from the game in the third inning, having struggled with command and given up two home runs, including Acuña's third of the day. Reliever Tanner Rainey, the Nationals' most reliable arm all season, surrendered a grand slam to Freddie Freeman to tie the game in the fourth inning. Led by Turner, the Nationals scored just enough runs to win, as struggling closer Daniel Hudson gave up a two-run home run but still earned the save. The Nationals recalled third baseman Carter Kieboom on September 5, designating longtime utilityman Wilmer Difo for assignment in a corresponding move. "We've got to see what we’ve got," manager Davey Martinez explained, describing Kieboom—despite his struggles at the plate before he was optioned to the alternate training site in late August—as his everyday third baseman for the rest of the season. The bullpen and offense came through again in the September 5 game, with McGowin making his season debut and throwing 2⅓ perfect innings, earning the win and picking up another lackluster start by Fedde, who allowed all four of the Braves' runs as the Nationals again scored ten times. Also that day, the Nationals announced a contract extension for general manager Mike Rizzo through the 2023 season. Corbin struggled again on September 6 and took the loss as the Braves salvaged a series split, giving up five runs and exiting after 5⅓ innings, as it was Atlanta's turn to put up ten runs to three for the Nationals. In a highly unusual move, Rizzo was ejected during the game by umpire Joe West after, West claimed, the Nationals general manager showered verbal abuse on the umpiring crew from his suite two levels above home plate over a questionable call.
After placing rookie reliever Dakota Bacus on the injured list, the Nationals recalled reliever James Bourque. The Nationals swept the Tampa Bay Rays in a two-game interleague set on September 7 and September 8. Scherzer pitched well in the series opener, putting up seven strong innings as the Nationals prevailed 6–1. The second game was more competitive, but the Nationals won 5–3, aided by Soto's return to the lineup, Kieboom's first extra-base hit of the season (an RBI double), and perfect innings of relief from Doolittle and Rainey. The two-game sweep was tempered as veteran infielder Howie Kendrick landed on the injured list with a nagging hamstring injury, with the Nationals selecting the contract of 32-year-old minor league outfielder Yadiel Hernández from the alternate training site to replace him.
Rainey's revival didn't last long, as he took the loss on September 10 when the Braves clawed back from a five-run deficit before Dansby Swanson gave them the lead with an eighth-inning home run. Making matters worse, the Nationals lost Doolittle to another injury in the ninth inning. Done for the season, Doolittle was placed on the injured list with an oblique injury, and the Nationals recalled left-hander Ben Braymer to the bullpen. Following another blown save for Hudson that sent the game into extra innings, Bourque earned his first major league win pitching in relief for the Nationals on September 11, coming on in the twelfth inning after scoreless tenth and eleventh innings authored by Kyle Finnegan. Taylor delivered the walkoff single for Washington to cap the seesaw 8–7 affair. The Braves took the four-game series by winning the next two games, with Corbin allowing just two runs over seven innings on September 12 but getting just one run of support and Scherzer getting clobbered for six runs over 5⅓ innings on September 13 to take the loss.
The Nationals split a pair with the Rays at Tropicana Field. Playing without Rainey, out for the season with a right flexor strain, and utilityman Brock Holt, out for the birth of his second child, and with reliever Aaron Barrett and infielder Jake Noll up from the alternate training site to replace them, the Nationals were pummeled 6–1 on September 15 as Aníbal Sánchez gave up all of the Rays' runs in 4⅓ innings. They recovered to win in extra innings the next day, with Luis García hitting a game-winning home run into right field in the tenth after another blown save by Hudson.
The Miami Marlins and Nationals had some games to make up from earlier in the season due to the Marlins' COVID-19 outbreak, so a five-game series that included two doubleheaders in three days was scheduled. The Nationals won the first and last games of the five-game set, shutting out the Marlins 5–0 behind a strong start from Erick Fedde, who allowed just one hit over six innings, in the matinee on September 18 and then shutting them out again 15–0 in the nightcap on September 20, with Braymer earning his first career win thanks to an effective five-inning spot start and ample run support. Sandwiched in between, the Marlins came back to crush Crowe and the Nationals' bullpen in a 15–3 blowout in the night game on September 18, which ended with a returning Holt coughing up a three-run homer to Brian Anderson in his major league pitching debut; hammering Corbin for a career-high 14 hits allowed and sending him to yet another loss in a 7–3 game on September 19, the only nine-inning game of the series under the 2020 season's doubleheader rules; and winning the first game in the September 20 doubleheader, a tough 2–1 loss for Scherzer, with the go-ahead run scoring on a Kieboom throwing error, despite a strong pitching performance for the Nationals' longtime ace.
The Nationals beat the Phillies on September 21 behind a five-inning start from Sánchez and four scoreless innings from the bullpen, although they lost Kieboom for the season when he was hit on the hand by a pitch, suffering a bone bruise. Playing their third doubleheader in the span of less than a week, the Nationals swept both games against Philadelphia on September 22, with Voth earning his first win of the season in the matinee and the 32-year-old rookie Hernández hitting his first major league home run to walk off in the nightcap, as journeyman Paolo Espino made the spot start for the Nationals. The Phillies exacted a small measure of revenge, savaging the Nationals 12–3 and handing Fedde the loss on September 23, despite Fedde posting his longest outing of the year at seven innings while giving up three runs, two of them on home runs by former Nationals teammate and fellow Las Vegas native Bryce Harper. After McGowin and Ryne Harper struggled in relief, Holt took the ball for his second pitching appearance of the season. The Nationals were formally eliminated that night from playoff contention.
Finishing the season with four games against the division-rival New York Mets, with whom they were now battling for fourth place in the National League East Division, the Nationals dropped the series opener on September 24 as Corbin lost his seventh straight decision. To catch the Mets in the standings and finish out of last place in the division, by dint of a better head-to-head record, the Nationals had to win out—and they did, starting by winning yet another doubleheader on September 26 following a rainout. Harris notched his first save with the Nationals in the first game of two on September 26, securing the 4–3 win for Scherzer. The Nationals were propelled by an unlikely offensive powerhouse. Starting in left field and leading off for the Nationals, with Soto moving over to right field, Andrew Stevenson hit two home runs off Mets ace and reigning Cy Young Award winner Jacob deGrom, including an inside-the-park home run in the fifth inning as Mets left fielder Dominic Smith ran into a wall and couldn't get up quickly. In the second game of the doubleheader, Sánchez received support in the form of a five-run third inning that gave the Nationals all the offense they needed to win, 5–3. The Nationals punctuated the season in emphatic fashion on September 27, winning 15–5 and giving Voth his second win of the season. Turner hit a grand slam off Mets starter Steven Matz in the game, while Soto singled to secure the National League batting title, the youngest qualifying player ever to lead the league in hits over a season.
Despite a rough start to September, the Nationals managed a 14–14 record of wins and losses over the month, bringing them to a 26–34 season record that was good for a fourth-place finish in the National League East, one year after earning a wild card berth into the playoffs and winning the 2019 World Series.
