"We thought he would be fine. He has not had any hiccups since rehab," Giants manager Bruce Bochy said. "Buster is coming through all the stuff we put him through and we think he is really back to where he was. He's not showing any ill effects of the injury."
Posey caught eight innings Friday and also shined on the basepaths. He ran hard to first base in the fifth inning for an infield hit and later scored from second base and slid home feet-first in a close play at the plate. He said he experienced "normal" soreness Saturday morning.
"I'm really optimistic because I think I have made a lot of progress this spring," he said. "I think it's only going to get better and better."
Posey was penciled in the lineup at first base Saturday against the Reds and said he hopes to catch as many games as possible when the regular season begins.
"He's going to do a lion's share of the catching. I don't know how many games," Bochy said. "I think we can answer that a little bit better as we get into the season. He'll be our starting catcher and occasionally he'll play first base to keep his bat in there. We'll keep an eye on him."
