SAN FRANCISCO -- Buster Posey hasn't yet played an inning at first base, but he'll spend some time there by the end of the season, manager Bruce Bochy said Wednesday.
Posey has started 32 regular-season games at first base, mostly in the middle of the 2010 season before Bengie Molina was traded to Texas.
Playing Posey at first would conceivably give the Giants another right-handed bat in the lineup when they face tough left-handers. Under this circumstance, Brett Pill likely would play left field, adding to San Francisco's right-handed-batting complement.
Philadelphia's Cliff Lee, Wednesday's starter, is as tough a left-hander as they come. But Bochy sought a balance between offense and defense, so he started Pill at first base, kept Posey behind the plate and left the outfield of Melky Cabrera, Angel Pagan and Nate Schierholtz intact.
"Putting Buster on first base adds an option," Bochy said. "But I did not want to do that tonight."
