A free agent pickup prior to the season, the right-hander proved to be a valuable part of the Rockies bullpen late in the season.
The mess that was the Colorado Rockies bullpen in 2015 had few bright spots, but one of them was right-hander Justin Miller.
The 28-year-old was signed as a minor league free agent from the Tigers, with whom he had a 5.11 ERA in 12u2153 innings in 2014, in the offseason and did not make his Rockies debut until June 17. Miller made 34 appearances for the Rockies, pitching 33u2153 innings despite being shuffled between Colorado and Triple-A Albuquerque several times throughout the season.
