Rockies backup catcher Jordan Pacheco suffered an injury to his left shoulder during batting practice on Monday, according to Patrick Saunders of the Denver Post, and was scratched from the lineup prior to the team's game against the Mariners.
Pacheco was replaced in the Rockies' lineup by Kent Matthes and could be out of action for a while as the club waits for the results of a "precautionary" MRI, notes Saunders.
UPDATE: Pacheco already underwent the MRI today and the team should know the results on Tuesday, according to MLB.com's Thomas Harding. Pacheco will be shut down for at least two days.
This shoulder injury couldn't possibly have as much of an effect on the team as the one currently being dealt with by Jhoulys Chacin, but it could have an impact in the roster nonetheless. If Pacheco doesn't get the reps he needs in order to be a viable backup catcher at the big-league level, it's a very plausible scenario that Michael McKenry will break camp with that job, possibly leaving the out-of-options Pacheco in DFA limbo.
For now, that's simply speculation, as the injury appears to be a minor one. It's still a situation worth keeping an eye on, though. Pacheco faltered badly last season after hitting .309 as a rookie in 2012. The 28-year-old New Mexico native hit just .239/.276/.312 in 262 plate appearances for Colorado in 2013.
