I don't want the Sox paying 9 million dollars for Clement. Perez will cost less thanks to his poor performance in the postseason. I think he's better than Clement anyway.
Perez has thrown more innings than Clement in the last three years, yet has given up just over half the number of walks Clement has. Clement's night ERA is a run higher than his day ERA in that span as well. Perez had the fourth best WHIP in the NL, Clement fourteenth. Perez also a ground ball pitcher like Clement, so you lose nothing there.
