SAN FRANCISCO -- Manager Bruce Bochy stopped short of calling the Giants' shortstop job a platoon, but he said Saturday that rookies Brian Bocock and Emmanuel Burriss will have nearly an equal share of playing time.

Burriss was in the lineup Saturday, his third start since being called up from Triple-A a week ago. Bocock, who broke camp as the replacement for injured Omar Vizquel, has started 22 of the first 25 games.

"I'll be using both of them," Bochy said. "I don't know if it will be 50/50, but it will be fairly close."

Bocock has more than held his own defensively and figures to maintain a slight edge in playing time, but he is batting .172 and has struck out 22 times in 64 at-bats. Burriss isn't as advanced defensively, but had three hits in his first eight at-bats, including a 13th-inning double Wednesday that sparked the winning rally at San Diego. He recorded his third stolen base in the second inning Saturday.

"Whatever they ask me to do, I'm doing it," Burriss said. "I just want to help."

Both Burriss and Bocock were in Class A at this time last year, so neither has a track record against big league pitchers. But Bochy said pitching matchups will help decide how he deploys the right-handed hitting Bocock and the switch-hitting Burriss.

"Tonight, I just wanted to get a left-handed bat in there," Bochy said.

Molina sidelined

Catcher Bengie Molina was not in the lineup and also could miss today's game because of what Bochy called "general soreness in his legs."

Molina, who leads the Giants in home runs (4), RBIs (16) and hits (25), told Bochy he felt some discomfort while he was legging out a double Friday night. Molina was slowed by a quadriceps injury in spring training.

"I don't want to risk setting him back," Bochy said. "He said he just felt it a little bit. We're just being cautious."

Winn returns

Right fielder Randy Winn was back in the lineup after missing the previous two games because of a sore neck.

Eight is enough

Closer Brian Wilson's eight saves are the most by a Giant through April since Matt Herges had eight in 2004. Only Robb Nen (nine in 1999) and Rod Beck (11 in 1997) have recorded more saves quicker.

Roberts on mend

Dave Roberts, who underwent arthroscopic surgery April 12 to clean up arthritis in the patella femoral joint in his left knee, hopes to begin walking without crutches today. Roberts said he will begin rebuilding the strength in the knee with flexing exercises. Doctors expect him to be sidelined until at least mid-June.
