Brandon Moss stroked a pair of home runs and finished with three RBI to back a solid start from Dan Straily, as the Oakland Athletics downed the New York Yankees, 5-2, Wednesday in the middle test of a three-game series.
John Jaso knocked in a pair of runs to provide more than enough support for Straily (4-2), who held the Yankees to two runs on three hits and a walk over 6 2/3 innings.
Grant Balfour stranded runners on first and second in the ninth to secure his 17th save and the A's 10th straight home victory.
The win also vaulted Oakland into the top spot in the AL West after the Texas Rangers fell to the Cleveland Indians earlier on Wednesday.
Jayson Nix and Mark Teixeira each registered an RBI for the Yankees, who managed just three hits in falling for the third time in five games.
New York starter Phil Hughes (3-5) was tagged for all three runs on four hits and five walks over 4 1/3 frames.
