Oakland scored three times in the ninth inning, then Coco Crisp hit a go-ahead single in a three-run 10th as the Athletics feasted on a shaky bullpen for a startling 7-4 win over the White Sox.Crisp entered the game in the ninth as a pinch-runner and was in a 3-for-22 slump before singling off Matt Thornton (0-2). The struggling closer had walked Conor Jackson and Josh Willingham to set up Crisp.Daric Barton followed with a two-run single and Thornton was booed as he was walked off mound and was replaced by Tony Pena.Cliff Pennington’s two-out, two-run, bases-loaded single in the ninth off Thornton made it 4-all. It was the third late-inning meltdown by the Sox bullpen in less than a week, all resulting in tough losses.With the White Sox leading 4-1 in the ninth, reliever Chris Sale gave up a leadoff double to Jackson, an RBI single to Willingham and a single to Hideki Matsui.

The Sox tied it in the fifth when Pierre reached as Anderson fumbled his comebacker for an error and Gordon Beckham doubled.

NOTES—Pierre reached base five times Wednesday – on three hits, an error and a walk. … White Sox manager Ozzie Guillen said the fans’ reaction to Pierre on Tuesday night, giving him a mock cheer every time he catches a fly ball, was unfair to the left fielder. Pierre twice dropped fly balls during the current homestand that led to late meltdowns and losses by the White Sox. “He doesn’t deserve that,” Guillen said. There were a few boos in the third inning Wednesday when Pierre fumbled Pennington’s single for an error, allowing him to advance to second base. Pierre now has three errors in 12 games. He made only one error in each of the previous two seasons combined, a span of 305 games. …Guillen also said that as of now he “has no closer.” … Oakland’s Andy LaRoche made his sixth start of the season at a fourth different position, this time getting the nod at first base.
