The Boston Red Sox have acquired Jake Peavy from the Chicago White Sox in a three-team deal that also sent shortstop prospect Jose Iglesias to Detroit Tigers.

The slick-fielding Iglesias provides a nice insurance policy for AL Central-leading Detroit in case Jhonny Peralta is suspended as part of baseball's Biogenesis drug investigation.

Peavy is 8-4 with a 4.28 ERA in 13 starts this season. The 2007 NL Cy Young Award winner was considered the best starting pitcher on the market ahead of Wednesday's non-waiver deadline.

With Clay Buchholz on the disabled list with a shoulder problem, the move gives Boston another proven starter for the stretch run in the tough AL East.

The Red Sox also got reliever Brayan Villarreal from the Tigers. They sent three minor leaguers to the White Sox as part of the deal.
