The Angels win a wild game over the Orioles, 9 – 8, in 12 innings. The Angels score three runs in the bottom of the 12th inning after the Orioles score two in the top of the frame. The Halos rally against O’s closer Kevin Gregg, as Erick Aybar singles and Mike Trout is hit by a pitch; a first run scores on 3B Josh Bell’s throwing error fielding Hank Conger’s bunt, then Peter Bourjos is safe on an infield hit that loads the bases. Alberto Callaspowalks to tie the game, and with Troy Patton now on the mound, Bobby Abreu hits a sacrifice fly to center for the walk-off win.

Dan Uggla homers twice and drives in 3 runs as the Braves top the Diamondbacks, 8 – 1. Freddie Freeman also homers in support of Brandon Beachy.

After a stint with the AAA Toledo Mud Hens and exactly one month after having been designated for assignment, Brandon Inge is back in the Tigers’ line-up. He homers in his first at-bat and doubles in a run his next time up as Detroit defeats Cleveland, 10 – 1, increasing its lead in the AL Central to 3 games.

Cubs chairman Tom Ricketts fires general manager Jim Hendry, the man who brought the perennial losers within five outs of the World Series in 2003 and built back-to-back division winners in 2008 and 2009, after 9 years on the job. Hendry’s success was achieved at the cost of a massive payroll, however, and the team is now on the hook for a number of expensive contracts to underachieving former stars, while headed for a second consecutive 5th-place finish. His players send Hendry out a winner as pinch-hitter Tyler Colvin hits a walk-off single in the 10th inning to give the Cubs a 5 – 4 win over the Cardinals on his last day. Assistant GM Randy Bushis named to take over in the interim but is not in line to succeed Hendry.

DH Mitch Moreland slugs two home runs and drives in five runs as the Rangers defeat the White Sox, 7 – 4.

1B Mike Jacobs, currently playing for the Colorado Springs Sky Sox in the Pacific Coast League, is the first North American professional athlete to test positive for human growth hormone. He receives a 50-game suspension from Major League Baseball, and is released by the parent Colorado Rockies.

Leading 1 – 0 entering the bottom of the 9th, the Rangers cough up the game when reliever Mike Adams gives up a two-run walk-off home run to Angels rookie Mark Trumbo. A loss by the Angels would have virtually eliminated them from contention in the AL West; with the win, they are 6 games behind Texas and still have a glimmer of hope.

Mike Jacobs becomes the first professional baseball player to be suspended for testing positive for human growth hormone. The 30 year-old Rockies minor league first baseman, who has played for the Mets, Marlins, and Royals, is handed a 50-game suspension for his involvement with HGH.

The injury-ravaged Giants, missing their top two relievers, closer Brian Wilson and set-up man Sergio Romo, build an early 7 – 1 lead over the Braves behind the pitching of Matt Cain. Things get more difficult when the bullpen takes over in the 9th and gives up four runs until Jeremy Affeldt manages to strike out Brian McCann, representing the tying run, for the last out in a 7 – 5 win. The slumping Giants manage to pick up a game on the Diamondbacks in the NL West race.
