You responded to a comment about McCutchen vs righties and then posted all stats. .683, .652, .558 (this year) ops vs righties the last 3 years. Players normally gradually get worse as they progress into their mid 30's. And at this point its just about 1/3 into the season. You can argue hes going to get better if you want, but including stats vs lefties in response to a post about him hotting righties is misleading.
I should say that I liked the signing because hed still been hitting lefties, am fine with him in the lineup vs lefties (for now), and I havent called for him to be DFA'ed.
