There has never been any doubt about Santiagos arm. He has a high level D1 pop time. Perhaps you might want to focus on the young pitching staff keeping runners honest, slide step, etc.
I dont have any idea how many times Santiago has struck out, but I think he was leading the team in BA just 2 weeks ago. Could be wrong about that. Regardless, there are many holes on this team, but Im not so sure you are focused on the right one. He steal your girl or something?
