Derek Norris hit a two-run homer in the second, Jarrod Parker pitched seven strong innings and the Oakland Athletics beat the San Francisco Giants 6-2 on Tuesday night for their fifth straight victory.

Adam Rosales homered in the eighth for the A's to snap an 0-for-24 funk since he connected against Kansas City on May 17.

Nate Freiman hit an RBI single and Jed Lowrie and Seth Smith each drew bases-loaded walks as Oakland (30-23) won for the 10th time in 11 games to move seven games above .500 for the first time since April 19.

Hunter Pence homered in the ninth and hit an RBI single in the first to give Mike Kickham a lead before he took the mound for his major league debut.
