A sore left groin kept Omar Infante out of the starting lineup against the Astros at Marlins Park. Donnie Murphy started at second base for Infante, who is hopeful to be back in the lineup on Sunday.
Infante said he felt some discomfort on his final two swings in Friday's 5-4 win in 11 innings.
Off to a .367 batting average, Infante said he was available to pinch-hit on Saturday.
"We don't want to take any chances," said Marlins bench coach Joey Cora, filling in as Ozzie Guillen serves his five-game suspension. "If we need him today, he will be there. And hopefully tomorrow he will start."
The day of rest is more of a precaution.
"It's not worth it. It's too early in the season," Cora said. "He came up at the end of the game, and he was sore. He came out today saying he's OK. We decided it ain't worth it. Probably, if it was September and we were in the middle of the pennant race, he'd be out there. Now it doesn't make any sense."
Infante is 11-for-30 with three doubles, a triple, three home runs and five RBIs in eight games. He's riding a six-game hitting streak.
On Wednesday in Philadelphia, Infante was shaken up when he was run into by Hunter Pence on an interference play.
Infante said he was fine after the collision.
