Orioles Beat Boston, Gain Tie for AL East Lead The Baltimore Orioles tied atop the AL East with the New York Yankees with four games left, a scenario that might cause a team unaccustomed to being in a pennant race to stumble under pressure. Not these guys. After Baltimore beat the Boston Red Sox 4-3 Saturday night to earn a share of first place, Orioles first baseman Mark Reynolds described the mood of the team as "a quiet confidence." "Calmness," Reynolds said. We're playing with house money. We're not supposed to be here. We're just a bunch of kids having fun. We go out every night believing we're going to win the game, no matter what the situation and no matter who we're facing. It's just fun to be a part of. Chris Davis hit his 30th home run and rookie Manny Machado lined a go-ahead shot in the seventh inning for the Orioles. After finishing in the division cellar in each of the previous four seasons, Baltimore (91-67) is tied with a team very much accustomed to finishing in first place. The Yankees lost to Toronto before this game started, so the Orioles knew they would earn a share of the lead with a win. Baltimore went ahead 3-0 in the fourth, then let Boston pull even before Machado homered, a liner into the second row of the left-field seats off Felix Doubront (11-10). Baltimore Orioles' Chris Davis, left, jogs past Boston Red Sox catcher Jarrod Saltalamacchia for a run on a single by Manny Machado in the second inning of a baseball game in Baltimore, Saturday, Sept. Machado has been a major leaguer for all of 47 games after being summoned from Double-A Bowie on Aug. 9. "I'm just trying to play the game," he said. Obviously, it's bigger than any other games I've played before. I'm just going to try and go out there and give everything I can to help this team win. It was another tight victory for the Orioles, their trademark in this unimaginable season. Baltimore is 28-9 in one-run games and 72-0 when leading after seven innings. "It's an honor to sit there and watch it and marvel at what these guys can do, especially when certain things start snowballing," manager Buck Showalter said. And you create your karma. These guys have done a good job of doing that, and they're expecting good things to happen. Tommy Hunter (7-8) pitched two innings, Brian Matusz and Darren O'Day shared the eighth and Jim Johnson got three outs for his 49th save. A sellout crowd of 46,311, a majority of them clad in Oriole orange, brought Camden Yards back to a time when the home team was a force in the AL East and the ballpark was packed on a nightly basis. The fans got to cheer a Baltimore great before the first pitch, too. A statue of Hall of Fame third baseman Brooks Robinson was unveiled during a ceremony in the flag court beyond the center-field wall. The Orioles' goal is to capture the division, but if they win two more games they are at least assured of their first trip to the playoffs since 1997 - their last winning season before this year. Baltimore now is 41-27 in the division and New York is 37-31, so if Baltimore wins one more game, it will have home-field advantage if there's a playoff to decide the AL East title. "The pressure's on both of us," Reynolds said. Four games left, dead heat. I guess there's a possibility of two playoff games. It's what we play for, and it's fun.
