Unless the Astros make a move for outside catching help, Pena is likely to open 2016 as the No. 2 catcher behind Jason Castro, Evan Drellich of the Houston Chronicle reports.
Pena lacks experience above Double-A and is hitting just .192 over 28 Grapefruit League plate appearances. If he does open 2016 with the Astros, his stay in Houston may be short-lived, as it's widely assumed the team will make a move for outside catching help with Max Stassi (wrist) on the shelf until May at the earliest.
