Cal Quantrill

Quantrill's run of success came to a screeching halt last season, as he made a pair of trips to the injured list with shoulder trouble and struggled to an ERA north of 6.00 in his final 12 starts. While it was obvious that the right-hander had been pitching over his skis since coming over from San Diego, it was still somewhat surprising to see his performance crater like it did. The injury almost certainly played a part, but regardless the Guardians designated Quantrill for assignment after the season, later sending him to the Rockies via trade. Quantrill has always been subject to the whims of variance given his low strikeout rate (career 17.7 K%), and adding Coors Field to the mix makes him a highly combustible element. Colorado is hoping he can provide stability in the middle of the rotation, but it will be tough in that division. Read Past Outlooks
