It was a tale of two halves for the Yankees’ bullpen last season. Up to the All-Star break, Yankees’ relievers ranked second in the majors in WAR (4.5) and ERA (2.89) while leading the league in FIP (3.05). But after the midway point, the unit took a step back. Their ERA rose 19 points to 3.08 and their FIP went up nearly 70 points to 3.74 — falling to 15th in the league— due to a dropoff in strikeout minus walk rate (moving from 15.9 to 12.4 percent).
On the other hand, Ron Marinaccio represented something of an exception: he was good to begin with and just kept getting better.
