Nickeas hit .174 with one home run and 13 RBI in 122 plate appearances over 47 games for the Mets in 2012. He is a career .180 hitter in 191 plate appearances over three seasons with the Mets.
I don't think this is any indication Nickeas will be on the big league roster, especially if they acquire a bigger upgrade behind the plate. He provides value as a mentor and is well liked among his peers. I recall during voluntary workouts last February Bob Geren telling Josh Thole to watch Nickeas' catching mechanics, remarking at Nickeas' throwing position and his “consistency” in his ability to receive pitches and throw the ball to second base.
However, Nickeas doesn't hit much, and so he is a backup catcher on a Major League team, at best. Still, there's no harm in bringing him back to camp this Spring, having him work with the younger pitchers again, and even with Thole on the things he must work on going forward.
