SAN FRANCISCO -- The San Francisco Giants acquired right-hander Jake Peavy from the Boston Red Sox on Saturday for a pair of minor league pitchers.
He will start Sunday night's series finale against the Los Angeles Dodgers. The Giants held a half-game division lead in the NL West against their rival going into Saturday night's middle game at AT&T Park.
San Francisco is sending right-hander Heath Hembree and lefty Edwin Escobar to the World Series champion Red Sox in the swap.
Peavy (1-9, 4.72 ERA) has been hurt by poor run support this season, receiving two runs or fewer of support in each of his past eight starts.
Yusmeiro Petit had been scheduled to pitch Sunday for the Giants with right-hander Matt Cain on the disabled list (see full story).
Cardinals: Veteran catcher Pierzynski signs
CHICAGO -- The St. Louis Cardinals have signed veteran catcher A.J. Pierzynski.
Pierzynski, 37, was in the starting lineup and batting sixth for the Cardinals' afternoon matchup against the Chicago Cubs. Catcher George Kottaras was designated for assignment to make room on the roster.
The Cardinals have been looking for a steady presence behind the plate since All-Star Yadier Molina went down with a torn ligament in his right thumb on July 9. Molina underwent surgery on July 11 and is expected to miss 8-12 weeks.
The left-handed hitting Pierzynski played 72 games this year with the Boston Red Sox, hitting .254 with four home runs before being released on July 16. He has a career average of .282 over 17 seasons with six teams (see full story).
Hall of Fame: Election eligibility cut to 10 years
COOPERSTOWN, N.Y. -- The Baseball Hall of Fame has reduced the number of years a player can remain eligible to be voted in by the writers to 10 years from 15, giving Barry Bonds and Roger Clemens less time to be considered.
The Hall of Fame announced the changes Saturday. They are effective immediately and will be reflected in 2015 Hall of Fame voting by the Baseball Writers' Association of America.
Bonds and Clemens, record-breaking stars whose careers have been tainted by allegations of performance-enhancing drug use, have been on the ballot the last two years.
The BBWAA will allow three players -- Don Mattingly, Lee Smith and Alan Trammell -- who have been on the ballot between 10-15 years to complete a 15-year stay (see full story).
