Fri Apr 04 17:20:00 UTC 2025: ## Rockies Call Up Top Pitching Prospect Chase Dollander for Sunday Debut

**Denver, CO – April 4, 2025** – The Colorado Rockies are promoting their highly touted pitching prospect, Chase Dollander, to the major leagues. The 23-year-old right-hander will make his MLB debut starting Sunday, according to reports from Just Baseball.

Dollander, a ninth overall pick in the 2023 draft, has quickly risen through the Rockies’ minor league system. Last year, he impressed across High-A and Double-A, compiling 118 innings over 23 starts with a 2.59 ERA, a 33.9% strikeout rate, and a 9.4% walk rate. He is currently ranked among baseball’s top prospects, appearing on several publications’ top 100 lists.

While the Rockies considered adding Dollander to their Opening Day rotation, he began the season with Triple-A Albuquerque, where he pitched four innings, allowing one run in a single start. This call-up likely stems from the injury to starter Austin Gomber, who is sidelined with shoulder inflammation.

Dollander’s debut presents a significant challenge: pitching at Coors Field, notorious for its hitter-friendly environment. However, analysts point to Dollander’s low release point and high-spin fastball (96-98 mph) as potential advantages in the thin air. He also features a changeup, curveball, and a slider/cutter.

The Rockies will need to make a corresponding roster move to accommodate Dollander’s promotion. His call-up also makes him eligible for prospect promotion incentives, requiring him to win Rookie of the Year or finish top 3 in MVP or Cy Young voting before reaching arbitration.
