Boston, MA (Sports Network) - Matt Wieters knocked in the winning run in the ninth inning, as Baltimore clipped Boston, 3-2, in the opener of a three-game series from Fenway Park.
Chris Davis clubbed his team-record 51st home run and Brian Roberts added an RBI for the Orioles, who have won three of their last four.
Tommy Hunter (6-4) recorded the final two outs of the eighth, while Jim Johnson tossed a scoreless ninth for his 46th save. Scott Feldman walked a career-high six batters over his five-inning start, but allowed just two hits and one run.
Dustin Pedroia homered and Xander Bogaerts drove in the other run for the Red Sox, whose three-game win streak was snapped but whose magic number to clinch the AL East was reduced to three after Tampa Bay lost to Texas.
Koji Uehara (4-1) served up the lead run in the ninth. Ryan Dempster worked six full frames, giving up two runs on three hits with five strikeouts and four walks.
