NEW YORK -- Initially, Bill Hall thought -- or hoped -- he had just gotten the wind knocked out of him. But upon ranging into foul territory to retrieve Willie Harris' popup in the second inning, and turning in a fabulous play in the process, the Astros' second baseman wound up spraining his right ankle and will now miss some time.

The injury, however, wasn't deemed serious. Hall, walking around the clubhouse postgame with a slight limp, will be out of the lineup for the series finale against the Mets at Citi Field on Thursday, but isn't expected to sit much longer. Manager Brad Mills called it "day-to-day, but probably a couple of days, anyway."

Hall said he hurt himself when he jammed his foot up against a pole beneath the padding on the wall that extends out from the Mets' dugout on the first-base side.

"It's not that serious," Hall said after the Astros' 4-3 win over the Mets. "All the exercises and tests that were done, it's not hurting that bad to get an MRI. It just got tough for me to run around. I just wanted somebody out there that was going to be able to make all the plays."

Hall's lower half collided with the wall as he went full extension to make the play on Harris' popup.

"It was an outstanding play," Mills said, "going over there and fighting the crowd and the sign and everything else."

But Hall appeared shaken up afterward and was checked on by Houston's medical staff. He opted to stay in the game, then struck out against R.A. Dickey in the third and was replaced by Matt Downs for the start of the bottom of the fourth.

"I'm a guy that don't like to come out of games," Hall said. "I was trying to make it work, but I didn't want to hurt the team at the same time."

Hall, batting .197 through 17 games this season, said he'd try to be available off the bench on Thursday, though Mills would likely try his best to not have to use him.

"We want that thing to be healed," Mills said. "He hit that sign down there and kind of twisted it, and we just want to make sure he's 100 percent."
