Pierson Ohl Bio
Pierson Blaine Ohl is an American professional baseball pitcher currently listed with the Colorado Rockies organization of Major League Baseball (MLB). A right-handed pitcher, Ohl came up through the Minnesota Twins system and reached the major leagues during the 2025 season. He previously attended Grand Canyon University, where he developed into a draft-eligible arm before beginning his professional career.
Born on September 10, 1999, Ohl is a Southern California native who has built his career steadily through the minor leagues. After debuting in the majors with Minnesota, he was traded to the Colorado Rockies organization in January 2026, though a subsequent elbow injury has since interrupted his on-field progress.
Early Life and Background
Pierson Blaine Ohl grew up in the Simi Valley area of Southern California, a region long known for producing competitive baseball talent. He attended Grace Brethren High School, where he played for the school’s baseball program and developed the foundation for his future career on the mound.
Following high school, Ohl chose to continue his baseball career at Grand Canyon University in Phoenix, Arizona. The Grand Canyon program offered him an opportunity to face strong college competition and to refine his pitching arsenal while earning a college education. His work at Grand Canyon helped position him as a draft prospect heading into the 2021 MLB Draft.
Path to Baseball
Ohl’s path to professional baseball moved quickly after his time at Grand Canyon University. The Minnesota Twins selected him in the 14th round, 429th overall, of the 2021 Major League Baseball Draft, marking the official start of his professional career.
He began his professional journey at the lowest rung of the minor-league ladder, suiting up for the rookie-level Florida Complex League Twins. From there, he moved up the organizational chain, gaining valuable innings and experience against progressively older and more experienced competition as he worked toward the major leagues.
Pierson Ohl Career
Early Career (2021–2022)
After being drafted in 2021, Pierson Blaine Ohl began his professional career with the Florida Complex League Twins, working his way into the routine of a full professional schedule. He used that early experience to prepare for a full-season assignment the following year.
In 2022, Ohl moved up to the Single-A Fort Myers Mighty Mussels, where he made 20 appearances, including 18 starts. Across 91 and two-thirds innings, he posted a 6-7 record with a 3.53 earned run average and 101 strikeouts, showing the kind of swing-and-miss stuff that would become a hallmark of his profile.
Minnesota Twins Breakthrough (2023–2025)
The 2023 season saw Pierson Blaine Ohl split his time between the High-A Cedar Rapids Kernels and the Double-A Wichita Wind Surge. In 24 appearances, 21 of which were starts, he logged 127 and one-third innings and produced a 9-7 record, a 3.32 earned run average, and 115 strikeouts, cementing his status as a legitimate upper-minors prospect.
Ohl returned to Wichita for the 2024 season, transitioning into a more flexible role that included work out of the bullpen. In 21 games and 15 starts, he covered 102 innings, posted a 4-7 record and a 4.68 earned run average, and added 70 strikeouts along with one save, demonstrating his ability to handle both starting and relief duties.
The 2025 campaign was the year everything came together. Ohl began the year on the injured list but recovered in time for two rehabilitation outings with Fort Myers before being reassigned to Wichita. In 13 games with the Wind Surge, he went 4-1 with a 2.08 earned run average, struck out 46 batters, and added a save, earning a promotion to the Triple-A St. Paul Saints on June 23, 2025. On July 29, 2025, the Twins selected Ohl to the 40-man roster and promoted him to the major leagues for the first time. He went on to make 14 appearances, including three starts, for Minnesota, finishing his rookie year with an 0-3 record, a 5.10 earned run average, and 27 strikeouts in 30 innings of work.
Colorado Rockies Era (2026–Present)
Pierson Blaine Ohl’s time with the Twins concluded when he was designated for assignment on January 23, 2026. Five days later, on January 28, 2026, he was traded, along with Edouard Julien, to the Colorado Rockies in exchange for Jace Kaminska and cash considerations, giving him a fresh start in a new organization.
His transition to the Rockies was soon complicated by injury. On February 23, 2026, it was announced that Ohl required season-ending Tommy John surgery after being diagnosed with a torn ulnar collateral ligament in his right elbow, sidelining him for the rest of the 2026 campaign as he begins a long rehabilitation process.
Driving Style and Strengths
Ohl is a right-handed pitcher whose profile has been built on a strong strikeout rate throughout the minor leagues. Across his time in the Twins system, he consistently missed bats at every level, and his Double-A and Triple-A results suggest he is at his best when working as a starter with regular rest. His ability to bounce between starting and relief roles, highlighted during the 2024 season, also points to a pitcher with the kind of versatility organizations value.
Notable Events and Milestones
Ohl’s most significant milestone came on July 29, 2025, when the Minnesota Twins selected his contract and promoted him to the major leagues for the first time. The trade to the Colorado Rockies in January 2026 marked another pivotal moment in his young career, and although his subsequent Tommy John surgery diagnosis is a setback, it also represents a defining chapter as he works toward a full return to the mound.

Minor League Highlights
In 2023, Ohl put together his most complete minor-league season, going 9-7 with a 3.32 earned run average and 115 strikeouts across the Cedar Rapids Kernels and Wichita Wind Surge. In 2022, he had posted a 6-7 record with a 3.53 earned run average and 101 strikeouts for the Fort Myers Mighty Mussels, and he returned to Wichita in 2024, where he went 4-7 with a 4.68 earned run average in a hybrid starting and relief role.
Other Wins and Performances

2025 Season Performance
Pierson Blaine Ohl’s 2025 season was a breakthrough year that began with adversity and ended with a major-league debut. He opened the year on the injured list, but he returned to action with two rehabilitation appearances for Fort Myers before being reassigned to Wichita, where he quickly got back on track with a 2.08 earned run average across 13 games.
His strong work in the minor leagues earned him a promotion to the Triple-A St. Paul Saints on June 23, 2025, and less than five weeks later, on July 29, the Twins called him up to the major leagues for the first time. He made 14 appearances, including three starts, for Minnesota down the stretch, providing the organization with a look at a young arm with continued minor-league upside.
Although Ohl finished his rookie major-league campaign with an 0-3 record and a 5.10 earned run average in 30 innings, the season still represented significant progress for a pitcher who had started the year on the injured list. His strikeout numbers and the velocity of his ascent through the system left the Twins optimistic about his long-term potential before his eventual move to the Colorado Rockies organization in January 2026.
