Bullpen roles are more or less steady now, but there are always players bubbling with potential. That's why it's important to stay on top of the latest closer developments.
Arizona Diamondbacks
Over his last six appearances, Mark Melancon posted three disaster games, leading to 10 runs and 13 baserunners over 1.1 innings. He delivered his sixth and seventh saves in eight tries in his three appearances. Melancon already has five losses with 25 baserunners allowed over 11.2 innings. Ian Kennedy has three saves in four opportunities, but he has already issued nine walks over 15.2 innings. Joe Mantiply (0.66 ERA and 0.73 WHIP) and Kyle Nelson (1.23 ERA and 0.75 WHIP) have pitched well enough in this bullpen to be in consideration for saves.
