Kemp's HR in 10th Spoils Harper's Strong Debut Perhaps one day, Bryce Harper will be hitting home runs at Matt Kemp's current pace - although very few can. For now, the Washington Nationals' top prospect can take satisfaction out the fact he hit a rope over Kemp's head in center field for a double in the third at-bat of his major league debut. Harper also drove in the go-ahead run in the ninth inning with a sacrifice fly and Wilson Ramos added an insurance run for the Washington Nationals with an RBI single. But closer Henry Rodriguez gave both runs back in the bottom half with the help of three wild pitches, and Kemp homered leading off the 10th to give the Los Angeles Dodgers a 4-3 victory on Saturday night. "Kemp hit a bomb, and that's terrible," Harper said. But he's a great player and a great hitter. He's hitting like .440 right now with 11 jacks and 24 RBIs. I know that if I had a number one pick, he'd be it. He's unbelievable. Harper, the Nationals' much-ballyhooed 19-year-old outfielder and the first overall pick in the 2010 draft, was 1 for 3 in his four plate appearances. He started out by hitting a comebacker in the first inning and flied out in the fifth. Los Angeles Dodgers' Matt Kemp celebrates after hitting a walk-off home run in the tenth inning of their baseball game against the Washington Nationals, Saturday, April 28, 2012, in Los Angeles. The Dodgers won 4-3. Because of the Nationals' rainout last Sunday at Miami, Stephen Strasburg didn't get the marquee matchup with NL Cy Young winner Clayton Kershaw that many had hoped for. But the Nationals' ace right-hander still had his hands full keeping up with Chad Billingsley, who matched zeros with him until both teams scored a run in the eighth against the two starters. Billingsley threw a great game and we fought 'til the end. But I wish we would have gotten the W, of course. Kemp drove a 1-2 pitch off Tom Gorzelanny (1-1) to center field for his majors-leading 11th home run, breaking the Dodgers record for long balls in April set by Gary Sheffield in 2000. Kemp tossed his helmet as he galloped from third to home plate, where he was mobbed by teammates. Jamey Wright (1-0) pitched a perfect inning for the win. Strasburg allowed one run and five hits over seven innings, struck out nine and walked none in his Dodger Stadium debut before a rollicking crowd of 54,242. "I knew it was going to be a loud stadium tonight, so I just wanted to go out there and keep my composure, pound the strike zone and do my best and keep the team in the ballgame," Strasburg said. This was a tough one for us. Rodriguez, trying for his sixth save and first since tag-team partner Brad Lidge went on the disabled list on Friday, gave up a ground-rule double by Juan Uribe - one pitch after a fan ran onto the field and was tackled in left-center by security guards.
