Jimmy Rollins said he is day to day.

We'll see.

He sprained his left ankle trying to get back to second base on a pickoff attempt in the eighth inning of today's 5-2 victory over the Mets at Shea Stadium. Rollins isn't certain if will be able to play tomorrow night in Game 2 of the three-game series.

"The ankle is fine," he said. "I'm able to walk pretty much without a limp. It's just when I did it I heard a nice little pop and it felt like somebody dropped a weight on my foot. I probably could have gone out there (to play shortstop in the eighth inning), but me at 50 percent and (Eric) Bruntlett at 100 percent, I'd rather have him out there.

"I don't know what happened. I guess my cleat got stuck. I was more concerned about my knee popping than anything, but the ankle went. Ankle or the knee, I'd rather have the ankle any day. It feels fine right now. We'll see how it feels over night, try to get off of it as much as I can. The way it feels right now I'll be able to go, but we'll see."

Rollins remained in the game after he injured the ankle and scored the game's fifth run. He went 2 for 5 with two runs scored and one RBI.
