Cardinals first baseman Albert Pujols left last night's game against the Reds with tightness in his hamstring after trying to run out a grounder in the seventh inning.
The Cardinals have Monday off as they travel to Houston to begin a three-game series with the Astros on Tuesday.
Will he be able to play?
"I think it all depends on how I wake up tomorrow," Pujols said, per Tom Timmermann of the St. Louis Post-Dispatch. "The tests were pretty good. They don't think it's too bad. When I wake up tomorrow, I can sense a little more about how I feel. Hopefully it's not as bad as I feel right now. I'll be glad we have a day off tomorrow.
"I'll show up here early tomorrow, get treatment and we'll go from there. Right now, if I told you I was going to be playing Tuesday, I don't want to say yes and not be there. ... Hopefully, in my prayers, I feel good, have a good day off tomorrow, travel, and on Tuesday I'll be ready to go."
Pujols got off to a slow start and was hitting only .150 through April 11th's win over Arizona. In his past 12 games, however, Pujols has 16 hits in 48 at-bats (.333 average) with six home runs and 13 runs batted in.
