RHP Connor Van Scoyoc: The 6-foot-6 righty is starting the season in the Double-A rotation and could be a fast mover this year. He came to Colorado from the Angels via a trade for Mike Moustakas last year.

LHP Ryan Rolison: Colorado’s first-round pick in 2018 missed all of 2022 and then most of ’23 due to injury. He’s starting the season on the 60-day IL in Triple-A, but could be a stop-gap when he gets healthy.

LHP Carson Palmquist: A third-round pick in 2022 will start in the Double-A rotation, and could be waiting in the wings by late summer if he continues his ascension after a 3.90 ERA in 19 starts in ’23.

RHP Jeff Criswell: The A’s second-round pick in 2020 was acquired in a trade for Chad Smith in December 2022. He was a non-roster invite to spring training and made 26 starts in Triple-A last season.

RHP McCade Brown: He’ll be rehabbing until about midseason from Tommy John, but the Rockies are still high on Brown, who turned in a 5.22 ERA for Class-A Fresno last summer before getting hurt.

LHP Sam Weatherly: The southpaw is working his way back from a shoulder injury that cost him all of last season, and he has a 4.69 ERA in 20 minor-league games (18 starts) but none above High-A.

RHP Chase Dollander: Colorado’s first-round pick last year didn’t pitch in the minors in 2023 coming off a high workload at Tennessee, but with a fastball touching 98 and a plus-slider, he could rise fast.

RHP Gabriel Hughes: Colorado’s first-round pick in 2022, had a 6.21 ERA in 14 starts across High-A and Double-A before undergoing Tommy John surgery. He could be back late in the second half.

LHP Michael Prosecky: The southpaw turned in a strong 2023, with a 2.72 ERA across 13 starts for Fresno. He’ll be tested in the upper minors this season to see if he can continue that momentum.
