People are questioning why would AA now give up anything for a front of the rotation starter when he could have just signed one in the offseason. The answer is simple, it wasn't a great need in the offseason when they had Stroman, now that he's gone they need to replace his production because Sanchez can't fill the void. Whether or not he was durable for the entire season no one can answer, but that's what the trade deadline can be used for. A rental.
