Carter took a ball off his right hand as he slid to second base against the Rangers on Friday, causing some soreness and pain when he put pressure on it or swung a bat.
"Everything is good," Carter said before the game. "It's been four days now. I got a couple pinch-hits, but it's good to be back out there again."
Carter sat out Saturday, and pinch-hit Sunday and Tuesday. Manager Bo Porter said Carter could have started Tuesday in St. Louis, but he wanted to see the left fielder go through a full batting practice before returning to the lineup. The Astros didn't take batting practice Sunday and then had an off-day Monday, so Tuesday was Carter's first opportunity to do so.
"I wanted him to go through a complete batting practice where he feels the impact and report no ill effects or setbacks before we put him into the lineup," Porter said. "Today he's back in there and he should be good to go."
