What does that mean? Not that much. It's better than the alternative, but we've seen Arrieta dominate Triple-A before. The organization is keeping him in the rotation for now, but they're eventually going to have to think long and hard about how Arrieta fits and what's best for his development. It's just a guess on my part, but I'm thinking Arrieta might eventually be moved to the 'pen, where he can concentrate on pitching in smaller spurts. Once he's successful there, you hope he can expand that approach.
