OAKLAND, Calif. — The Oakland Athletics have acquired shortstop Stephen Drew from the Arizona Diamondbacks in exchange for minor league infielder Sean Jamieson.

The A's announced the trade in the seventh inning of Monday night's game against the Minnesota Twins, and Drew is expected to join Oakland in time to play the middle game of the series on Tuesday. He recently returned after being sidelined for nearly a year with a fractured right ankle.

The 29-year-old Drew is batting .193 with two home runs and 12 RBIs in 40 games since coming back June 26.

Oakland, a surprise contender this season, had been looking for a consistent regular in the middle of the infield given the struggles and injuries of Cliff Pennington and Adam Rosales.
