Chase Dollander, the Colorado Rockies' top pitching prospect, is set to make his Major League Baseball debut against the Oakland Athletics at Coors Field. After being left off the opening day roster, Dollander's impressive spring training and a stellar 2024 season, where he posted a 2.59 ERA across High-A and Double-A, solidified his spot in the rotation. Rockies manager Bud Black praised his skill set, stating he possesses a dominant four-pitch mix and a good mentality for a young player.

His debut comes at a time when the Rockies' starting rotation has the best ERA in the league but has struggled to translate those performances into wins. Injuries, particularly to Austin Gomber, have created the opportunity for Dollander, who is expected to be a cornerstone for the franchise moving forward.
