Had a wRC+ of 123 in August, really it was just one terrible month in September. A .107 BABIP is crazy bad luck so I wouldn't look much into it.
He's great vs RHP and he would only be a platoon bat with Upton anyway. Plus like Morales he's always been in s*** home parks like Oakland and St Louis, perhaps there is some potential given he's an extreme flyball hitter.
