I don't think he's going to be very effective if he can't hit 93-94 MPH. I don't know what he was hitting at Chattanooga, but if he's topping out at 90, he's not going to strike out many guys in the majors... I think it'd be better to give him some more time rehabbing and get Romero back in the rotation.
Think I have to agree with you and spycake here.
I think he needs to make his Rochester start and we'll see how he looks. Might even need another to ramp it up. Then we can see how he looks for the Twins. A waiver wire trade after a few successful starts may be the optimum.
I like the guy and have loved watching him pitch. I'm rooting for him, trade value or not.
Some part of me keeps wondering though, back next year on a lower end deal with incentives? A 1 year for $7M? Possibly even in a milb deal if it takes longer than expected to really get it going? Just a thought.
