The Marlins are going to ask David Phelps to start after a successful year in relief. The problem is, outside of velocity, he is not doing anything different that should lead to the success he has gotten.
The Miami Marlins smartly converted David Phelps, long-time swingman, into a full-time relief role, and he shined with a strong first half. He made 50 relief appearances and threw 54 1/3 innings with a 2.65 ERA and 2.82 FIP. FanGraphs has this performance as the 18th-best in the majors among relievers, mostly on the back of Phelp’s workload.
