One piece the Rays didn't have last year was a multi-inning reliever: Manager Joe Maddon ran a matchup bullpen filled with short relievers, so everyone who made at least 15 relief appearances averaged fewer than one inning per outing. While it worked—Tampa Bay won the AL wild-card spot—a team breaking in a rookie starter (Matt Moore) may need an option that can go longer. Rather than choose their long man based on who loses the rotation battle, though, how about deciding which from the pair of Wade Davis and Jeff Niemann actually fits best in a multi-inning role? Niemann has had more of his success the first two times through a team's lineup: in his career he has held opponents to a .704 OPS the first time through and .667 the second time, but has gotten pounded when he sees hitters a third time (.825). Davis is at his worst the first time through (.787 OPS allowed) and gets progressively better. Niemann gets rocked after 75 pitches; Davis shows no such pattern. Based on that data, Niemann is better suited to throwing multiple innings out of the bullpen. The Rays should make him their long man and leave Davis in the rotation.
