Marmol has a fine ERA for about 8 weeks. That's not the same as pitching fine. 19 IP, 19 K, 12 BB, 12 H, 1 HR That's about a 3.75 FIP from my back of the envelope math. Not awesome, not worth "WHY IS HE ON THE ROSTER" hand wringing. I don't want guys on the roster who have 3.75 FIPs when you cobble the endpoints together to make them look better.
