Cecil and Loup should be very good, and they seem determined to have Sanchez there, so if he's anything like that season he should be decent over a full season. Then if Estrada makes the rotation like I expect him to, then Redmond is the long man again. Which leaves three spots for high leverage innings between some combination of Delabar, Lopez, Drabek, Rasmussen, Jenkins, Guilmet, West, Perez, Infante, da Silva, etc.
It's not going to be a great pen, but I don't think it will be a weakness. The rotation if someone gets hurt is going to be in much bigger trouble.
