The Red Sox on Tuesday night made a bold move to improve their rotation by acquiring righthander Jake Peavy from the White Sox in a three-team, seven-player trade.
The price was steep: defensive wizard Jose Iglesias was traded to the Tigers along with three lower-level prospects. The Sox also obtained Triple A righthander Brayan Villarreal from Detroit.
The Sox sent righthanders J.B. Wendelken and Francelis Montas and infielder Cleuluis Rondon to the White Sox. Chicago also obtained outfielder Avisail Garcia from Detroit.
The 32-year-old Peavy is 8-4 with a 4.28 earned run average in 13 starts and was one of the best starters available on the trade market. Full story for BostonGlobe.com subscribers.
