The Orioles defeat the Yankees, 5 – 4, to tie the Bronx Bombers for first place in the AL East once again, but the win is costly. RF Nick Markakis breaks his left thumb when hit by a CC Sabathia pitch in the 5th inning, putting him out for the remainder of the year. Mark Reynolds, Lew Ford and J.J. Hardy homer for the Orioles. Closer Jim Johnson almost blows a 5 – 3 lead when he loads the bases on three singles with none out in the 9th; Nick Swisher brings the Yankees within one on a force out, before Mark Teixeira is declared out when sliding head-first into first base while vainly trying to avoid a game-ending double play. Teixeira and manager Joe Girardi blast umpire Jerry Meals for his call after the game.

The Nationals announce that they are shutting down ace pitcher Stephen Strasburg 

The Nationals announce that they are shutting down ace pitcher Stephen Strasburg in order to limit his innings on the mound in his first full season since undergoing Tommy John surgery. While other teams have taken similar decisions in the past, it is the first time a team involved in a pennant race has deliberately taken one of its top pitchers out of action of its own volition. Strasburg is 15-6, 3.16, with 197 strikeouts in 159 1/3 innings. His absence will be sorely felt when the Nats drop a five-game NLDS series to the Cardinals next month, in large part because of a lack of pitching depth.
