Over the course of 161 games, the Colorado Rockies’ bullpen made 543 appearances and threw 565 innings during the 2021 season. That number of appearances was the 12th lowest in baseball and the group threw the fourth fewest amount of innings during the season. So, the starting rotation picked up the slack and mostly kept the bullpen from getting over-taxed. Unfortunately, that couldn’t stop the bullpen from putting together a rough campaign.
