Can't be certain because until this year I obviously have never watched him hit on a nearly daily basis, but I've speculated he might be nursing some sort of minor hand/wrist injury that's affecting him for some time now. He is taking awkward swings and his bottom hand seems to come off the bat a lot, which is weird. But he's a long/big dude so it could just be a prolonged struggle and he might just look extra awkward when he's off. He's walking a lot less, too. I was really hoping the Cubs were getting a guy who kept on getting on base at a good clip.
