He's the worst. fielder. ever. and they still run him out there. Just because he has some offensive game. Now, imagine if he had power, they'd play him at catcher if they had to. Look at Bocock- excellent glove, can't hit and you'll never see him again.
Fielding is mostly about just making the routine plays and most big league athletes can handle that. The flashy plays are nice, but in the long run they really don't add up to much.
Remember, Jose Cuz, Jr won the gold glove in '03.
