Heading into the New Year, here’s a breakdown of 10 Rockies prospects — five of whom raised their stock with strong performances in 2025, and five of whom have the most to prove heading into 2026. This list only includes prospects who have yet to debut or those who have still retained their rook ie eligibility going into this coming season.

A crafty southpaw reliever with a low-three quarters arm slot who has a mid 90s fastball paired with a slider and changeup, he dominated High-A in ’25 (0.49 ERA in 15 games) and did well in Double-A (3.50 in 37). He also got the save for the NL in the Futures Game. OF/SS Cole Carrigg — The versatile Carrigg, Colorado’s second-round pick in 2023, is a switch-hitter with speed. In 2025, Carrigg turned in a decent season at Double-A Hartford even though his strikeout rate jumped up to 27%. If he can cut down on his Ks in ’26, and continue to improve upon his power (15 homers last season), he might fast-track himself to Coors Field. RHP Jackson Cox — The 2022 second-round pick got off to a slow start when his first full pro season was cut short by Tommy John, forcing him to miss all of 2024. But he returned to Low-A Fresno in ’25 and pitched well, with a 3.71 ERA in 23 starts. If he can keep that momentum up in ’26 across High-A and Double-A, he could be on track to be a mid-rotational starter in the bigs. OF Jared Thomas — The 2024 second-round pick has played mostly left field and center field, and looked good in the Arizona Fall League with a .302 average in 17 games. That followed a solid ’25 that saw him hit .300 across High-A and Double-A, showcasing gap-to-gap power plus speed on the bases to compliment above-average bat-to-ball skills that can play in LoDo. OF Sterlin Thompson — Another outfield prospect with an intriguing bat, the No. 31 overall pick in 2022 is knocking on the door of his debut after slashing .296/.392/.519 in a full season in Triple-A in 2025. Colorado added him to the 40-man in November, and he projects as a left-handed-hitting left fielder. He’ll surely get a chance to make a big-league mark in 2026.

After that stint in April, the 2020 No. 9 overall pick spent the rest of the season in Triple-A Albuquerque, which was telling of how the Rockies believed he needed more seasoning. Can Veen turn his cup of coffee into a regular MLB roster spot in 2026?

He had Tommy John surgery in 2023 and returned to pitch in the Arizona Fall League in 2024. In ’25, he had a 5.11 ERA in Triple-A. This year is his chance to prove he’s ready for a debut. OF Benny Montgomery — Check out the most recent Rockies’ Top 30 prospects rankings by MLB Pipeline, and Montgomery is conspicuously absent. The No. 8 overall pick in 2021 has been plagued by health issues, including a groin injury in 2022, a knee injury in ’23, and season-ending shoulder surgery in ’24. He needs to stay on the field, and put up solid numbers, in 2026. 1B/3B/OF Charlie Condon — After the No. 3 overall pick in the 2024 draft had a rocky debut as a pro that summer while he battled a bone spur in his finger, his ’25 was slowed by an early-season wrist injury. When he came back, he made it to Double-A and then the Arizona Fall League. But he’s only had 15 homers in 124 games; in 2026, the pop in his bat needs to come back. SS Ethan Holliday — If there’s any reason for hope that the Rockies can be competitive again down the road, Holliday must live up to the hype. Colorado’s first-round pick at No. 4 overall last summer has the skillset and pedigree to be a major-league star — now it’s time to start to prove it in his first full professional season. The goal should be to tear up the Class-A levels. Want more Rockies news? Sign up for the Rockies Insider to get all our MLB analysis. ...read more read less
