It is extremely dangerous to go with such a small sample of a few games in trying to compare Estrada & Narveson. Having a pitcher who has done well in MLB, down in AAA staying stretched out and pitching every 5 games is a great problem to have. If Narveson struggles for another 4 or 5 starts and Estrada continues to pitch lights out that is one thing, but I like the idea of having some strong pitching depth in AAA if needed. Narveson was phenomenal in his first few starts and now is averaging out towards his career norms, which is fine for a #5 pitcher. And let's see how Estrada does tommorow anyways. In terms of Estrada in the MLB bullpen or the AAA starting lineup, again I see real value in keeping him stretched out and ready to start as needed. Unless our bullpen implodes, which is not out of the realm of possibilities Right, but Narveson is basically pitching to his career norms. Yes, he's been a victim of the big inning, but that was the case last year as well. As far as Estrada goes, yes it is a small sample, but his stuff looks great to me. Why risk messing with a good thing by sending him to Nashville? If this is just a hot streak, I say ride it out, he may continue to blossom into a solid starter, or you may get a nice first half out of him (a la Victor Santos/Manny Parra 2008). Narveson can be the long guy in the bullpen until the inevitable starter injury occurs.
