Carson Palmquist Bio
Carson James Palmquist (born October 17, 2000) is an American professional baseball pitcher for the Colorado Rockies of Major League Baseball (MLB). A left-handed starter who rose through the minors after being drafted in 2022, he made his major league debut in 2025. Palmquist is regarded as one of the more promising young arms in the Rockies organization, having built a reputation for high strikeout totals and durable innings throughout his development.
Early Life and Background
Carson James Palmquist was born on October 17, 2000, and grew up in the Fort Myers area of Florida. He attended Riverdale High School, where he quickly emerged as one of the most dominant high school pitchers in the region. His senior season became the foundation of his professional reputation, as he carved up opposing lineups with remarkable consistency and control.
As a senior in 2019, Palmquist did not allow an earned run across more than 60 innings while striking out 106 batters. That performance drew attention from major league scouts despite his going unselected in the 2019 MLB draft. Rather than turn professional out of high school, he opted to continue his development at the collegiate level, a decision that would shape his path to the Rockies.
Path to Baseball
Following high school, Palmquist enrolled at the University of Miami to play college baseball. The move gave him the chance to refine his mechanics, build arm strength, and face higher-level competition in the Atlantic Coast Conference. His freshman year, however, was cut short by the cancellation of the 2020 season due to the COVID-19 pandemic.
As a redshirt freshman in 2021, Palmquist was named Miami’s closer and recorded 14 saves, the third-best total in college baseball that year. He went 1-1 with a 2.22 ERA and 75 strikeouts over 44-plus innings across 25 appearances. After the season, he earned a spot on the USA Baseball National Collegiate Team, an honor reserved for the top amateur players in the country.
In 2022, Palmquist transitioned into Miami’s starting rotation. Over 16 starts, he went 9-4 with a 3.54 ERA and 118 strikeouts in 84 innings. He later participated in the Draft Combine in San Diego, where he showcased his skills in front of big-league decision-makers.

2025 Season Performance
Palmquist entered 2025 as one of the most anticipated arms in the Colorado system. His early results with Triple-A Albuquerque, including a 3.82 ERA and 45 strikeouts across seven starts, justified the organization’s patience. Those outings set the stage for his promotion to the Rockies on May 16, 2025, marking his first appearance on a big-league mound.
Within Colorado’s rotation, Palmquist was viewed as a long-term option with swing-and-miss upside and the endurance to handle a starter’s workload. His promotion to the 40-man roster signaled that the Rockies view him as part of their next wave of young pitchers. The team’s focus on player development gave him an opportunity to log innings and adjust to major league hitters.
Heading through the balance of the 2025 season, Palmquist’s outlook depends on his ability to refine his secondary offerings and manage the offensive environments of Coors Field. His minor league track record suggests the raw tools are there, and the remainder of 2025 will determine how quickly he settles into a permanent big-league role.
