The Rockies are going to promote their top pitching prospect, reports Patrick Lyons of Just Baseball. Right-hander Chase Dollander will make his major league debut when he starts for the club on Sunday. There’s already an opening on the 40-man roster, so the club will only need to make a corresponding active roster move.
Dollander, now 23, has been a hyped-up name for a while now. He put up big numbers for Tennessee and was ranked as one of the top players available in the 2023 draft. The Rockies selected him with the ninth overall pick and then signed him to a slot-value bonus of $5,716,900.
He made his professional debut last year in impressive fashion. He tossed 118 innings over 23 starts, going from High-A to Double-A in the process. He allowed just 2.59 earned runs per nine, striking out 33.9% of batters faced while giving out walks at a 9.4% clip.
Going into 2025, the industry consensus is that he’s one of the top prospects in the league. Baseball America currently lists him #7 overall and MLB Pipeline #24. FanGraphs had him at #12 to start the season, but with the now-graduated Dylan Crews as one of the guys ahead of him. ESPN had Dollander at #14, though also behind Crews. Keith Law of The Athletic was more bearish, putting Dollander down at #75, with concerns about some of his results in Tennessee.
The Rockies reportedly gave some consideration to having Dollander in the season-opening rotation. They sent him to Triple-A Albuquerque instead, where he made one start, allowing one earned run over four innings. The big league club started the season with just four games before their first off-day, having Kyle Freeland, Antonio Senzatela, Ryan Feltner and Germán Márquez start those.
Austin Gomber likely would have had a fifth spot but he started the season on the 15-day injured list with shoulder soreness. He made a rehab start for Albuquerque but was scratched from making a second due to inflammation in that shoulder, per Thomas Harding of MLB.com. Perhaps due to Gomber’s setback, Dollander will get an early-season call-up.
The big unknown will be how Dollander handles the challenges of pitching at Coors Field, the most hitter-friendly venue in the big leagues. Geoff Pontes of Baseball America believes Dollander is well-positioned to succeed, even though plenty of other talented arms have struggled there. Pontes points out that pitchers with low release heights, such as Dollander, have previously fared well at Coors. The piece also cites the spin efficiency of Dollander’s fastball, which sits between 96 and 98 miles per hour, as a factor that could work in his favor. In addition that fastball, he throws a changeup, a curveball and another breaking ball that is characterized as either a slider or a cutter by various sources.
If Dollander can thrive at Coors, he could become the most important arm in the rotation for their next competitive window. The club has been losing for a long time now but have seen some young players come up and establish themselves as building blocks, such as Ezequiel Tovar at shortstop and Brenton Doyle in center field.
In the rotation, there’s little long-term certainty. Márquez and Gomber are impending free agents while the contracts for Senzatela and Freeland are only guaranteed through 2026, with options for 2027. It’s possible the Rockies sign new deals with those pitchers but they’re all in their 30s now regardless. At 23 years old, Dollander could potentially be the rock of the group for many years to come, if everything breaks right.
Though he wasn’t on the Opening Day roster, he is getting called up early enough to potentially earn a full service year in 2025. A baseball season is 187 days long but a player needs only 172 days on the active roster or injured list to get a full year. If he’s not optioned down to the minors at any point, he would be on track to qualify for free agency after the 2030 campaign, though a notable optional assignment would push that trajectory by one year.
If he does stay up, the Rockies would be eligible to potentially receive an extra draft pick. The current collective bargaining agreement introduced measures to combat service time manipulation. One such measure is that a team can earn an extra draft if they promote a top prospect early enough to earn a full service year. To qualify, a player must be on two of the three Top 100 lists of BA, ESPN and MLB Pipeline. The player must then win Rookie of the Year or place in the top three of MVP or Cy Young voting in their pre-arbitration seasons.
Those will perhaps be factors later in the year. For now, one of the best young pitchers in the game is coming up to the majors. Facing big league hitters for the first time is always a fascinating challenge for any pitching prospect but the interest level is arguably even higher in this case, given the unique circumstances of Coors Field and Dollander’s potential importance to the franchise.
