Francisco Alvarez exited Sunday’s game against the Mariners before the eighth inning after he appeared to injure his hand while sliding.

Matt Kawahara of the Houston Chronicle reports that Alvarez will begin a minor-league rehab assignment on Tuesday with Double-A Corpus Christi. He’ll serve as a designated hitter in his first rehab game back, and the club plans to have him down for “a few games” before he can be activated off the injured list.
