"I feel it a little bit, but we'll see what happens tomorrow," Infante said.
After driving a ball down the right-field line, Infante pulled up after rounding first base and hobbled into second with a double. He said it was the first time he had ever strained the muscle.
Infante, who was playing shortstop in place of the injured Yunel Escobar (strained left shoulder), had to be removed for pinch-runner Brent Lillibridge, who stayed in the game to play shortstop.
"I don't think it's going to be that bad," Braves manager Bobby Cox said. "He wanted to stay in and when I asked him to bend down and stretch it a little bit, [his hamstring] grabbed him pretty good."
Cox said it was too early to consider putting Infante on the 15-day disabled list. That could change Thursday if Infante has blood on the back of his hamstring, which would indicate a tear.
Lillibridge had not played shortstop for the Braves since April 26-27, when he made two starts against the Mets. He was recalled from Triple-A Richmond on Saturday to bolster the Braves' dwindling bench. They had just one backup infielder -- Greg Norton -- available on Wednesday.
Lillibridge's eighth-inning double was his first career Major League hit. He went 1-for-3 and had two assists.
