It's not just about last night. I'm just not sure he has the stuff to be anything better than a 4/5 SP'er.
We could use a good 4/5 pitcher, but there are some not-so-good ones, too.
I think he will get another start or two, and even a 3-4 game sample size is not much to work with, but I'd prefer to see Bello, when he is ready. I'm not sure Gio deserves anything, but he will likely get his shot when ready- like it or not.
