The worst part of calling him a "back-up," "sub" or "utilityman" is that he keeps following that up with some statement about him not "downing" Kike, when it is so obvious.
He has a 13.5 bWAR over his last 2400 PAs (690 games), which comes to about a 3.3 bWAR over 162 games and 3.4 over 600 PAs
While Kike is no stud, superstar or even a "star" player, he's damn good. He'd be a FT starter on just about every team in MLB.
