Athletics 10, Padres 2: Brandon Moss launched his fifth homer in four games to highlight a five-run first inning as host Oakland breezed to victory on the same day that it granted the request of veteran slugger Manny Ramirez for his outright release.
Signed to a minor-league contract in February, Ramirez served a 50-game suspension for violating Major League Baseball's policy on performance-enhancing drugs. Ramirez was originally slated to return to the majors at the end of May, but he did not progress to the Athletics' liking and remained with Triple-A Sacramento.
Cliff Pennington celebrated his 28th birthday by collecting three hits and driving in a pair of runs. Josh Reddick ripped a two-run triple and Brandon Inge and Coco Crisp had RBI singles for the Athletics, who have scored 36 runs and belted 10 homers en route to winning four in a row.
Staked to an early offensive explosion, Travis Blackley (1-2) posted just his second career victory after allowing two runs on five hits in six innings.
Anthony Bass (2-7) continued to struggle after permitting seven runs on six hits in five innings. He has given up 25 earned runs in 26 innings over his last five starts.
Carlos Quentin and Chris Denorfia had run-scoring singles for the Padres, who saw their three-game winning streak emphatically come to an end.
