He's either hitting everything he sees or hitting absolutely nothing. I don't think I have ever seen someone with so many 5-5 and 0-5 games in the same season.
I think you mean someone else. Rafael throws saves, at least on good days. Alfonso is really streaky, though. That's why when he got hot in July I didn't pick him up. All the hitting he did recently should make up for a couple of 0-fers.
