"It's really sore today," Schafer said. "Like they told me, with a sprain, the next day is probably going to be the worst. I'm just happy it's not broken.
"I'm OK with missing a couple of days, but I just didn't want the break and to miss a couple of months. I'm happy it's only a sprain."
Schafer has had plenty of problems with his left hand in the past. He had left wrist surgery at the end of the 2009 season, and last year, he broke a joint on his left middle finger. Schafer was on the disabled list with that injury when the Astros acquired him from the Braves last July as part of the Michael Bourn deal.
Schafer is having a terrific spring, hitting .391 (9-for-23), and will be Houston's starting center fielder. He drew a pair of walks Sunday, and scored two runs in his only two plate appearances as the leadoff hitter against the Mets.
