"With Nady going down, this move allows us to get both Belt and [Buster] Posey in there," manager Bruce Bochy said before Friday's game. "Buster is going to catch a day game tomorrow, and I knew he'd play first today and I didn't want to sit Belt. I look forward to him going out there."
Bochy talked with Belt about the possibility after Wednesday's game against the D-backs, and though he hasn't practiced any fly balls in the outfield since Spring Training, Belt headed there with confidence in his defensive play.
"I feel comfortable out there," Belt said. "Obviously I'm not going to be climbing any walls and robbing home runs, but I feel like I can do a good enough job to help us win."
Belt leads all Major League players with a .371 average since Aug. 1, with 11 runs and 13 RBIs in that span. He got some tips from outfielder Justin Christian and first-base coach Roberto Kelly about how to man left field at AT&T Park.
"I can definitely gain some confidence from this move," Belt said. "The coaches have enough confidence in me to be in the lineup every day and know that I can contribute. I think it'll help me play better, too."
The Giants also activated Christian from the disabled list before Friday's game to give the team further depth in the outfield.
