Renteria was hit by a pitch in the third inning of Friday's game and exited in the fourth because of soreness in the forearm. He was replaced in the lineup by Zack Cozart, who was called up on Thursday, and Cozart made his second career start Saturday night.
"I'm going to go out and try and hit right now and see what I can do. It's sore so we'll see," Renteria said.
Manager Dusty Baker previously said he plans to use both players at shortstop so Cozart can continue learning the ins and outs of the Major Leagues.
"He's a little sore, he's a little swollen where he got hit," Baker said. "I wasn't sure where it hit him yesterday, but it hit him in the forearm, which is always easily a place of soreness afterward. So I'm not sure."
