All season long, the Milwaukee Brewers’ bullpen has been an unexpected strength. After Devin Williams was injured in spring training, the relief group entered the season with question marks, and season-long struggles for two of last year’s best relievers, Hoby Milner and Joel Payamps, could have spelled doom. But the emergence of Trevor Megill and Bryan Hudson as elite relief options and of Jared Koenig and Enoli Paredes as unexpected sources of quality innings has given the Brewers one of the more reliable bullpens in the majors. Through Sunday, the Brewers had the third-best ERA by non-starters in the league.
