A Milestone Debut
Mason Adams is slated to take the mound on Tuesday as the Colorado Rockies open a series against the Washington Nationals, marking the culmination of a long‑awaited return to the big leagues.
Overcoming Adversity
The right‑hander’s path to the majors has been shaped by adversity; he underwent Tommy John surgery on April 2, 2025, and spent 16 months rehabilitating before earning a spot on the Rockies’ Triple‑A affiliate.
College Dominance
Adams’ college career at Jacksonville University was nothing short of dominant. He led the ASUN Conference with 108 strikeouts in 90 innings, earned ASUN All‑Tournament Team honors in 2021, and struck out seven in a championship‑game victory that cemented his reputation as a clutch performer.
Minor League Mastery
After being selected in the 13th round of the 2022 MLB Draft, he climbed steadily through the minors, posting a 2.92 ERA with 110 strikeouts over 120.1 innings for Triple‑A Charlotte in 2024, and later a 2.08 ERA in four scoreless frames for Albuquerque before the trade.
A Familiar Mentor
The move to Colorado was orchestrated at the August 3 trade deadline, when the Rockies acquired him from the Chicago White Sox, a transaction that also linked him to former coach Chris Hayes, under whom he had thrived at Jacksonville.
Adams joins a distinguished lineage of former Dolphin pitchers; he becomes the 15th Jacksonville University alum to reach the majors and the fourth to do so under Hayes, joining the likes of Austin Hays, who also earned a spot on MLB’s 40‑man roster.
His immediate impact was evident in his first outing, where he posted a 2.08 ERA over four innings, signaling that the Rockies have high hopes for the young arm as they look to bolster their rotation.
