As I've said before, I agree the baserunning instincts seem very green. He seems to also take a bit to get going to full speed.
Sliders from RHP give him fits. I don't really have high hopes for the guy on the Cubs, he needs to get Caissie'd to some team that can play him everyday and keep developing, hopefully he can turn into an everyday guy.
His main value for us IMO is he can play CF and backup PCA in case of injury. He can do that in AAA, unfortunately for him.
Maybe he'll get more playing time next year for us, but they don't even like him as a RHB platoon bat or pinch runner this year. If he can't even hit LHP for us next year he needs to go.
