CHICAGO (AP) Billy Butler hit a three-run homer in the ninth off David Robertson, and the Oakland Athletics rallied for a 4-2 win over the Chicago White Sox on Thursday.

Chicago was leading 2-1 heading into the ninth, but Robertson (6-4) blew his seventh save in 36 chances when he allowed a double to Brett Lawrie, a single to Danny Valencia and Butler's 13th homer.

White Sox right fielder Avisail Garcia jumped at the wall and appeared to catch Butler's drive, but the ball fell out of his glove and into the Oakland bullpen as he hit the fence.
