Ryan Perry Rolison (born July 11, 1997) is an American professional baseball pitcher for the Chicago White Sox of Major League Baseball. Rolison was a first-round selection by the Colorado Rockies in the 2018 MLB draft after a standout college career at the University of Mississippi and made his major league debut during the 2025 season.
Early Life and Background
Ryan Perry Rolison was born in Jackson, Tennessee, and attended the University School of Jackson in his hometown. He developed as a high-school pitcher with exceptional strikeout numbers and statewide recognition, finishing his senior year with a 9–0 record and earning Tennessee’s DII-A Mr. Baseball honors.
Rolison’s high-school performance included a junior-season 0.74 earned run average and more than 100 strikeouts, achievements that put him on collegiate programs’ radar. He chose to enroll at the University of Mississippi rather than sign out of high school after being selected in the 2016 draft, electing to continue his development in college competition.
Path to Baseball
At the University of Mississippi, Rolison moved from bullpen work as a freshman into the starting rotation and quickly established himself as a prospect. He posted a 6–3 record with a 3.06 ERA as a freshman and earned SEC All-Freshman honors and Freshman All-American recognition while also spending a summer with the Orleans Firebirds of the Cape Cod Baseball League, where he performed as an all-star.
Rolison’s sophomore season further raised his draft stock: he went 10–4 with a 3.70 ERA and recorded 120 strikeouts over 17 appearances, drawing pre-draft attention that culminated in his selection in the first round of the 2018 MLB draft.
Ryan Perry Rolison Career
Early Career (2018–2021)
The Colorado Rockies selected Ryan Perry Rolison with a first-round pick (22nd overall) in the 2018 Major League Baseball draft, and he signed for a reported $2.9 million signing bonus. He began his professional career with the Grand Junction Rockies of the Rookie-level Pioneer League, making nine starts and posting a 1.86 ERA in his first pro appearances.
Rolison advanced through the Rockies’ minor-league system in 2019, starting the season with the Asheville Tourists before a promotion to the Lancaster JetHawks of the High-A California League. Over 22 starts with Lancaster he struck out 118 batters and participated in a minor-league All-Star Game. The 2020 minor-league season was canceled, interrupting development for many prospects including Rolison.
Colorado Rockies Breakthrough (2022–2025)
Rolison joined the Rockies’ 40-man roster in November 2021. Injuries disrupted the next phases of his career: shoulder trouble required surgery and caused him to miss the entire 2022 season. He returned to action in the organization in 2023 but faced additional stints on the injured list during that year, which limited his workload and delayed his progression to the major leagues.
Across 2024 Rolison transitioned to work primarily out of the bullpen while pitching for multiple affiliates, posting a 4.47 ERA with 35 strikeouts across innings with three levels of the Rockies’ system. In 2025 he began at Triple-A Albuquerque and was promoted to the major leagues, making his MLB debut after being selected to the 40-man roster and called up on May 11, 2025.
During his rookie campaign with the Colorado Rockies in 2025, Rolison made 31 appearances and recorded his first major league win on August 16, 2025, tossing a scoreless inning of relief against the Arizona Diamondbacks. He finished the season with mixed results as he adjusted to big-league competition, and the Rockies designated him for assignment in November 2025 following the season.
