For the first time in a long time, the bullpen was the Nationals’ biggest strength this season.
After so many years (in which they did win, I might add) of trusting unproven closers and acquiring top relief pitchers through trade deadline deals, general manager Mike Rizzo constructed a bullpen mostly through waiver claims and minor league deals that proved to be more than adequate for manager Davey Martinez.
Nine of the 11 relievers with at least 23 appearances out of the ‘pen produced a FanGraphs WAR of 0.1 or better. Only Andres Machado (51 appearances, -0.1 fWAR) and Steve Cishek (69 appearances, -0.3 fWAR) were left out of the bullpen’s top 10 in fWAR, which includes Sean Doolittle’s 0.3 in just six appearances.
Looking even further, they produced some impressive numbers.
Kyle Finnegan posted a 3.51 ERA and 1.140 WHIP with 11 saves in 66 ⅔ innings over 66 games. Carl Edwards Jr. had a 2.76 ERA and 1.226 WHIP in 62 innings over 57 games. Erasmo Ramirez recorded a 2.92 ERA and 1.077 WHIP in 80 ⅓ innings over 58 relief appearances en route to being named Nationals Pitcher of the Year. And Tanner Rainey had a 3.30 ERA, 1.300 WHIP and 12 saves before his season was cut short due to injury.
