SAN FRANCISCO — The Giants boosted their rotation for the stretch run by acquiring RHP Jake Peavy from the fading Red Sox on Saturday for two minor-league pitchers.
The 2007 NL Cy Young Award winner is scheduled to start tonight against the Dodgers. San Francisco held a half-game NL West lead against its rivals going into Saturday night's game.
The Giants have plenty of familiarity with Peavy, who pitched for manager Bruce Bochy with the Padres in the playoffs in 2005-06.
"It's great to be reunited with Jake," Bochy said by text message. "Look forward to working with him again."
Peavy, 33, went 1-9 with a 4.72 ERA for last-place Boston. He had received two runs or fewer of support in his past eight starts.
San Francisco received cash from Boston and is sending RHP Heath Hembree, 24, and LHP Edwin Escobar, 22, to the Red Sox. Both players were optioned to Triple-A Pawtucket.
CARDS ADD PIERZYNSKI: C A.J. Pierzynski signed with the Cardinals, choosing them from among several suitors 10 days after being released by the Red Sox. Pierzynski, 37, will fill in the gap left by an injury to All-Star C Yadier Molina, who likely will be out well into September.
BLUE JAYS: 1B Edwin Encarnacion, out since July 5 with a right quadriceps strain, suffered a setback while swinging a bat Friday and is unlikely to return before August.
METS: RHP Daisuke Matsuzaka went on the 15-day disabled list with right elbow inflammation.
