San Francisco has boosted its rotation for the stretch run by acquiring right-hander Jake Peavy (PEE'-vee) from Boston for a pair of minor league pitchers and cash.
The 2007 NL Cy Young Award winner will start Sunday night's series finale against the Los Angeles Dodgers.
The 33-year-old Peavy pitched one of his best games last Aug. 25 at Dodger Stadium. He tossed a three-hitter with five strikeouts and one walk in an 8-1 Red Sox victory.
Peavy is 1-9 with a 4.72 ERA but has been hurt by poor run support. He's only received two runs or fewer of support in each of his past eight starts.
Peavy is earning $14.5 million this season, with the Red Sox paying more than $3 million of his remaining salary for the year.
