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.
Sean Doolittle (1-0), the third A's reliever, pitched a scoreless eighth and ninth. Rookie starter Sean Nolin allowed two runs and five hits in five innings in his third start since being recalled from Triple-A Nashville on Sept. 4.
White Sox starter Jose Quintana pitched crisp four-hit ball through seven innings and Mike Olt homered for the second straight day.
Quintana allowed one run, struck out six and walked only one. In his last 20 innings, the left-hander has allowed only two earned runs on 15 hits, while fanning 16.
Chicago's Matt Albers pitched a perfect eighth before Robertson came on.
Marcus Semien also drove in a run for the Athletics. Lawrie went 3 for 4.
Olt homered for the second time with the White Sox, who acquired him off waivers from the Cubs on Sep. 5.
