One of the stable parts on this Houston Astros team is their starting catcher Jason Castro. Although there has been quite a bit of a drop off in his offensive production and lineup appearances, only hitting .211 with a .648 OPS and 11 home runs in 108 games, he has been a stable option behind the plate in his five years in an Astros uniform. Last season, Castro helped lead Astros pitching to a team 3.57 ERA and a .241 batting average against. With a stable defensive option to start behind the plate, there are many directions the Astros can go in to back up Castro.
