Stassi had surgery on his left wrist to fix a hook of the hamate fracture and will be out six weeks, Jose de Jesus Ortiz of the Houston Chronicle reports.

EDGE Analysis

Stassi was the favorite to open 2016 as the No. 2 catcher behind starter Jason Castro, but the Astros will be forced to look on the waiver wire or trade market for a replacement. Alfredo Gonzalez is the only other catcher on Houston's 40-man roster, but he has yet to play above Double-A. Evan Gattis (sports hernia) has experience behind the plate, but he's rehabbing from injury and isn't a strong defender.
