One he plays defense something that is a need in the late innings because we all know Fresse gives away games with the glove, and two he is the only other player other than Aybar who can play short.
because he a rule 5 draftee and we have to keep him on the roster the whole year because if we send him down we have to give him back to the Colorado Rockies, and also he is the one player who can backup short and is good defensively.
