Carson Palmquist Bio
Carson James Palmquist is an American professional baseball pitcher for the Colorado Rockies of Major League Baseball. He made his major league debut in 2025 after a standout collegiate career at the University of Miami and several productive seasons in the Rockies’ minor league system.
Early Life and Background
Carson James Palmquist was born on October 17, 2000. He attended Riverdale High School in Fort Myers, Florida, where he emerged as a dominant high school pitcher. During his senior season in 2019 Palmquist recorded an exceptional run, striking out 106 batters and not allowing an earned run over the course of the year, a performance that drew scouting attention from professional teams.
Despite his high school success, Palmquist went unselected in the 2019 Major League Baseball draft and chose to enroll at the University of Miami to continue his development. The move to collegiate baseball positioned him to face stronger competition and refine his repertoire under an established college coaching staff.
Path to Baseball
At the University of Miami Palmquist arrived as a promising arm and quickly earned a role in the pitching staff. He made appearances as a freshman in 2020, posting effective numbers before the season was shortened due to the COVID-19 pandemic. His early college work established him as a reliable option in relief and set the stage for expanded responsibilities the following seasons.
Over the 2021 and 2022 seasons Palmquist transitioned through defined roles that showcased his adaptability and strikeout ability. He was named Miami’s closer in 2021, compiling 14 saves and a high strikeout total that placed him among the national leaders for saves. In 2022 he moved into the starting rotation, delivering a full season of work that increased his draft stock ahead of the 2022 MLB draft.

Early Career (2022–2023)
The Colorado Rockies selected Carson Palmquist in the third round with the 88th overall pick of the 2022 Major League Baseball draft. He signed with the organization for a reported $775,000 and made his professional debut that year with the Arizona Complex League Rockies, appearing in a brief relief outing as he began the transition to pro ball.
In 2023 Palmquist opened the season with the Spokane Indians of the High-A Northwest League and earned a midseason promotion to the Hartford Yard Goats of the Double-A Eastern League. Across 19 starts between the two levels he posted a 7–4 record with a 3.90 earned run average and compiled 134 strikeouts in just over 92 innings, a strikeout rate that reinforced his reputation as a high-contact-missing pitcher.
Minor League Progression (2024)
Palmquist returned to Double-A Hartford to start the 2024 campaign and earned a promotion to Triple-A Albuquerque later in the season. Over 27 starts between the two levels he worked to a 7–8 record with a 3.98 ERA and recorded 144 strikeouts in 117 2/3 innings. Those innings demonstrated Palmquist’s capacity to handle a starter’s workload and his readiness for higher competition.
The 2024 season solidified Palmquist as one of the Rockies’ promising pitching prospects, combining a starter’s endurance with swing-and-miss results. His progress through the system came as the organization evaluated its pitching depth and planned for potential major league needs.
Colorado Rockies Breakthrough (2025)
Palmquist began the 2025 season with the Triple-A Albuquerque Isotopes and delivered strong early results, recording a 2–2 mark with a 3.82 ERA and 45 strikeouts across his first seven starts.

He made his major league debut that same day as Colorado’s starting pitcher against the Arizona Diamondbacks at Chase Field, allowing five runs over four innings in an 8–0 game. Palmquist was optioned and recalled multiple times over the course of the season as the Rockies balanced development and roster needs. He appeared in nine major league games in 2025, including seven starts, while continuing to log significant innings at Triple-A.
Colorado Rockies Era (2025–Present)
The promotion to Colorado’s major league roster marked Palmquist’s arrival at the highest level of professional baseball and initiated a period of adjustment against elite competition. The Rockies used him in both starting assignments and spot starts as they evaluated his role within the rotation and as organizational depth. His early major league outings provided experience against major league lineups and identified areas for continued improvement.
Throughout the 2025 season Palmquist remained a young arm on a club managing innings and development timelines. The Rockies emphasized controlled workloads and repeated Triple-A assignments to maintain service time flexibility and to provide Palmquist with consistent innings between major league opportunities.
