Pinpointing the greatest pitcher in the history of the Colorado Rockies is a unique challenge given the notoriously difficult altitude and pitching environment at Coors Field, but franchise icons like Ubaldo Jiménez stand out for their historic accomplishments. Jiménez etched his name into team lore by throwing the first and only no-hitter in Rockies franchise history during his stellar 2010 All-Star season. Other notable hurlers like Jorge De La Rosa and Kyle Freeland also hold revered status in club record books for managing success and durability in a stadium heavily favored toward high-powered offense.
