The Cubs' bullpen was dominant over 25 innings pitched last week, helping Chicago win four of seven games vs. the Braves and Reds by posting a 1.80 ERA. All but three Cubs relievers finished the week unscored upon, helping the relief corps earn the Bullpen of the Week presented by The Hartford for the week of May 14-20.
As part of The Hartford Prevailing Moments program, each Monday throughout the 2018 season, MLB.com is honoring the previous week's top relief corps. An industry-wide panel of MLB experts, including legendary stats guru Bill James, constructed a metric based on James' widely renowned game-score formula, to provide a weekly measurement of team-bullpen performance.
