In Monday's 4-2 loss to Philadelphia, Gonzalez returned to the lineup for the first time since missing nearly a week with the same injury. Gonzalez initially suffered the calf strain in last Tuesday's loss to the Marlins.
"I'm not a betting man, but the chances are not good for him [Wednesday]," manager Fredi Gonzalez said. "Hopefully it's not one of those things that is a lingering thing. Hopefully it's just mild, you give him a couple days and he can bounce back. We'll know more [Wednesday]."
Gonzalez had been Atlanta's hottest hitter of late before the injury. He was hitting .467 (14-for-30) with three homers entering Monday.
Fredi Gonzalez said on Monday that he would pull his starting shortstop if he encountered problems with the calf, but Gonzalez didn't appear to have any problems in the series opener. He went 1-for-3 with a double and an RBI in that game.
