Arm strength produces + plays at 3B also. I usually play glove at 2B, arm at 3B. Of course, because 2B gets more action, that might be why you're getting an essential wash with your guys. I'd expect the 60 arm to produce some negs at 3B but it hasn't.
2B or CF. My guess is he's LH so CF. He could play 3B also(if not LH).
