When the story of the 2018 season is eventually written, the bullpen will likely play a role larger than the innings pitched. But will they be the heroes or villains? How they can be seen as having performed, depends enormously on what you look at. By ERA, they are among the best in the league, with their 3.42 figure worse only than the Cubs, and well below the NL average (4.06). On the other hand, their record of 21-31 gives them the lowest win percentage in the National League. Maybe they’re both good AND bad, for they rank above average both in the number of shutdowns and meltdowns - outings which changed WP by more than 6%.
