Normally, his throws are very tight with a lot of velocity. He threw some with awkward trajectory and not much zip today. I wondered if his thumb bothered him.
Anyway, I think the other issues were rust related. He needs to be quicker and I think he will be.
He's still got great potential and I expect much improvement next week.
A lot of fans would feel better if Shumway hadn't stopped on the deep ball thrown to him that could have been a 60 yard td pass.
