Dollander is the team’s No. 1 prospect, according to MLB Pipeline, who ranked him as the No. 24 prospect in all of baseball and the No. 5 right-handed pitcher.
The Rockies drafted Dollander with the ninth overall pick in the 2023 MLB Draft, and he worked in 23 games in 2024, totaling 118 innings across High-A and Double-A. He went a combined 6-2 with a 2.59 ERA, 2.92 FIP, and 12.9 K/9.
He was with the MLB team for spring training this season and went 2-3 with a 7.13 ERA and 6.39 FIP, but he did keep his strikeout total high with 24 punchouts in 17 2/3 innings. He had two back-to-back scoreless outings against the Guardians and Giants but was knocked around for six runs in 3 1/3 innings against the Brewers in his last appearance of the spring.
Dollander had five strikeouts in four innings while giving up one run in his only Triple-A appearance for the Albuquerque Isotopes. He will make his next start in the big leagues, though, facing the A’s on Sunday afternoon. He is definitely a top prospect to watch the rest of the season.
Fantasy baseball impact
With such good strikeout potential, Chase Dollander is definitely worth considering on waiver wires in season-long leagues. He has a high enough ceiling to be worth a speculative add if your roster can carry him. However, he is a risky pickup, given the uneven outings this spring and the fact that his home games will come at Coors Field.
The 23-year-old will give the Rockies rotation a good boost, though, and be an intriguing streaming option or DFS play with a high ceiling if only based on his punchout potential.
