Entering the 2021 season, the Colorado Rockies bullpen was viewed as one of the team’s biggest weaknesses, if not the biggest.
And that view was based in fact. In 2020, the Rockies had a bullpen ERA of 6.77, which was 29th in baseball and in 2019, they had a bullpen ERA of 5.18, which was 28th in baseball.
But since April 17 (the start of their last homestand, which started against the Mets), the Rockies bullpen has an ERA of 3.
