Jake Peavy will make his first start with the Red Sox on Saturday against the Diamondbacks, reports Joe McDonald of ESPNBoston.com.
Peavy was acquired from the White Sox on Tuesday night in a three-team deal that sent infielder Jose Iglesias to the Tigers. The veteran right-hander will take the rotation spot of Brandon Workman, who was optioned to Triple-A Pawtucket today and will work as a middle reliever in the minors.
Peavy, who recently returned from a rib fracture, owns a 4.28 ERA and 76/17 K/BB ratio over 80 innings in 13 starts this season. The Red Sox are hoping he’ll add some stability to a rotation which has been without Clay Buchholz for nearly two months.
