The Marlins second baseman was out Saturday and was expected to miss Sunday's game against the D-backs at Marlins Park. And manager Ozzie Guillen hasn't ruled out also sitting Infante on Monday in the series finale.
"I'd rather have him two days out than 15," Guillen said. "That's why we've got to monitor that very carefully."
Emilio Bonifacio played second on Saturday, while Chris Coghlan was in center field.
The sore left groin has now resulted in Infante not starting in five of Miami's first 20 games. Infante has been the team's most consistent hitter, batting .315 with five home runs and seven RBIs.
Guillen noticed Infante was a bit hobbled in Friday's 5-0 loss.
"He's been dealing with that for the last couple of weeks," Guillen said. "I didn't see him moving well yesterday. I doubt he is playing tomorrow. He isn't moving well at all.
"Hopefully we give him two days off. But it depends. I'll go by how he feels."
Infante did very little baseball activities on Saturday.
"Infante is going to say he is fine," Guillen said. "But I don't see him moving around the way he wants. Yesterday, he tried to beat out an infield hit. When you start pushing, then you get hurt, and we're done for a little while. We'll take care of it, little by little."
