RANKED: Every MLB Team’s Ace From Worst to Best

27. Jon Gray — Colorado Rockies

During the tail end of the 2017 season, Gray emphatically began to assert himself as the team’s ace. His impressive season came just a year after Gray finished sixth in Rookie of the Year voting for the National League. He undoubtedly has his best baseball ahead of him, and Colorado appears to be content with featuring him at the top of their rotation.

He’s been shaky to start 2018, including a brutal 15.0 inning stretch in which Gray allowed 18 runs. Colorado will afford him the opportunity to fail though, and hope that he picks it up when they need it most.
