The default with Colorado pitchers is to look at the home/road splits and try to ascertain how much Coors Field impacted his numbers. Occam's Razor suggests the most straightforward answer, so we look at the splits and see an 8.27 ERA at home (21 innings) and a 2.70 ERA on the road (20 innings) in near-equal samples. His fastball and changeup were obliterated at home to the tune of a combined 1.158 OPS in 86 plate appearances, versus a .678 OPS in 59 plate appearances on the road. The necessary caveats apply to a 41-inning sample, but it's not surprising that his stuff is less effective in Denver. It's just always going to be a problem for Colorado pitchers. We'll get seasons here and there, but long-term fantasy relevance at Coors Field seems impossible. It's not just the thin air, either, honestly it's usually more about the enormous outfield. Throw in the fact that he is slated to miss a month or more with a strained abdominal muscle to start the season, and Gray is best left untouched in standard leagues, until he is able to return and demonstrate his health. At that point he could be a useful streaming option in road starts.

Though their battered rotation presented several openings by midseason, the Rockies resisted the temptation to call up Gray and begin his service clock in the midst of a non-contending year. Gray likely would have forced the Rockies’ hand if he dominated in his first full season in the minors, but he was merely only very good at Double-A Tulsa, submitting a 3.91 ERA and 14.2 K%-BB% over 124.1 innings. It won’t preclude him from competing for an Opening Day starting gig with the Rockies this spring, but the organization probably prefers to give him a little more time in the minors to raise his performance before joining the big club later in the season and assuming his destiny as an anchor in their rotation. Having Coors Field as his eventual home park dampens Gray’s appeal more than most prospects of his caliber because of the expected ERA and WHIP hits, but the right-hander probably has a rosier fantasy outlook than the Rockies’ other highly-touted hurler, Eddie Butler, on the basis of his stronger strikeout rates.

After he was drafted third overall in the first-year player draft in June, Gray immediately made a splash on the professional stage. He was quickly advanced through rookie ball and proceeded to breeze through his five California League starts, going 4-0 with a 0.75 ERA and 36:6 K:BB ratio over 24 innings. With starting pitching being a sore spot for the organization practically since its inception, the Rockies have made it known they intend to fast-track Gray’s development, making a deployment to Double-A Tulsa or Triple-A Colorado Springs out of spring training a distinct possibility for the ascendant right-hander. At 6-foot-4 and 255 pounds, Gray possesses the ideal frame for a power pitcher and the repertoire to match. With a fastball that routinely touches the upper-90s to go along with his plus-slider, Gray projects as a high-volume strikeout artist at the next level and he should already attract attention in dynasty formats.
