The Astros claimed Hummel off waivers from the Giants on Thursday, Ari Alexander of KPRC 2 Houston reports.
The versatile Hummel is capable of catching and also playing the corner outfield spots. He has collected a .551 OPS over 76 games in parts of two seasons in the majors. Hummel has a minor-league option remaining, so Houston should report to Triple-A Sugar Land rather than stick around at the big-league level.
