Chase Dollander Bio
Tyler Chase Dollander, known professionally as Chase Dollander, is an American professional baseball pitcher for the Colorado Rockies of Major League Baseball (MLB). Born on October 26, 2001, in Evans, Georgia, he played college baseball for the Georgia Southern Eagles and the Tennessee Volunteers before being selected ninth overall in the first round of the 2023 MLB draft. A former top prospect, Dollander has pitched in both starting and relief roles for the Rockies and is widely regarded as one of the more promising young arms in the organization.
Early Life and Background
Tyler Chase Dollander was born on October 26, 2001, in Evans, Georgia, where he grew up in a tight-knit family with deep roots in the sport. He attended Greenbrier High School in Evans and quickly emerged as one of the most competitive young pitchers in the region. During his sophomore season in 2018, he posted a 5–3 record with a 2.36 ERA, signaling the arrival of a polished arm.
As a junior in 2019, Dollander went 6–1 with a 0.79 ERA and 71 strikeouts over 61 and two-thirds innings, drawing attention from college recruiters across the Southeast. When the 2020 MLB draft took place under the unique circumstances of that year, he went unselected, and he chose to continue his development in the college ranks. That decision ultimately set the stage for his rise into one of the top pitching prospects in the country.
Path to Baseball
Dollander enrolled at Georgia Southern University to play college baseball, joining the Eagles for the 2021 season. As a freshman, he made 11 starts and went 4–3 with a 4.04 ERA and 64 strikeouts over 49 innings, demonstrating a sturdy workload for a first-year college pitcher. After that debut season, he decided to transfer to a program with a more established national profile.
He landed at the University of Tennessee, where he joined the Volunteers and immediately became a key piece of their starting rotation in 2022. Over 16 appearances and 14 starts, he went 10–0 with a 2.39 ERA and 108 strikeouts over 79 innings, missing only about three weeks of action after being hit by a line drive. His dominant sophomore campaign earned him the Southeastern Conference Pitcher of the Year award and pushed him onto every national draft board. Entering 2023 as a top MLB prospect, he made 17 starts and went 7–6 with a 4.75 ERA and 120 strikeouts over 89 innings, cementing his status as a first-round talent.
Chase Dollander Career
Early Career (2024)
The Colorado Rockies selected Tyler Chase Dollander with the ninth overall pick in the 2023 MLB draft, and he signed on July 17, 2023, for a bonus of $5,716,900. He opened his professional career in 2024 with the Spokane Indians, the Rockies’ High-A affiliate, marking his first appearances in the minor leagues. Mid-July brought a promotion to the Hartford Yard Goats, the organization’s Double-A club.
Across 23 combined starts at Spokane and Hartford in 2024, Dollander went 6–2 with a 2.59 ERA and an eye-catching 169 strikeouts over 118 innings. His ability to miss bats at both levels reinforced the Rockies’ decision to fast-track him toward the major leagues.
MLB Debut and Rookie Season (2025)
After being invited to his first major league spring training in 2025, Dollander was assigned to the Albuquerque Isotopes to begin the regular season. On April 6, 2025, the Rockies promoted him to the majors, and he made his MLB debut that same afternoon against the Athletics. He earned the win after allowing four runs on seven hits with six strikeouts across five innings, an encouraging first outing on the game’s biggest stage.
His rookie season included an early stumble: the Rockies placed him on the injured list on May 22 with right forearm tightness, and he was activated on June 3. He was optioned to Albuquerque on July 7, with manager Warren Schaeffer noting publicly that he needed to improve his efficiency and throw more strikes early in counts. Recalled on August 11, Dollander pitched for the Rockies until mid-September, when a patella tendon strain in his left knee ended his year. Across 21 starts in his rookie season, he finished 2–12 with a 6.52 ERA and 82 strikeouts over 98 innings.
Colorado Rockies Era (2026–Present)
Heading into 2026, the Rockies named Dollander to his first Opening Day roster and announced a transition for him to the bullpen. In his first 10 appearances, including three starts, he compiled a 3–3 record with a 3.89 ERA and 47 strikeouts across 44 innings, a marked improvement over his rookie numbers. The team appeared to value his swing-and-miss stuff in shorter stints.
On May 15, 2026, however, the Rockies placed him on the injured list with a right elbow sprain, and he was transferred to the 60-day injured list on June 12. The same day, the club announced that Dollander would likely require surgery to repair damage to the ulnar collateral ligament in his right elbow, a significant setback for the young pitcher.
Driving Style and Strengths
Dollander is recognized for his swing-and-miss arsenal, particularly a sharp breaking ball and a fastball that has historically produced high strikeout rates, including 169 strikeouts in 118 innings across the minors in 2024. The Rockies have emphasized improving his efficiency and his ability to throw more early-count strikes, areas his manager publicly identified as developmental priorities during his rookie year. Working out of the bullpen in 2026 gave him a chance to focus on shorter, high-leverage outings while refining his command.
Notable Events and Milestones
Among his most significant moments are his MLB debut win over the Athletics on April 6, 2025, and his selection as the ninth overall pick in the 2023 MLB draft, the highest a Tennessee pitcher had been taken in years. He was also named the Southeastern Conference Pitcher of the Year in 2022, the signature individual honor of his college career.

Chase Dollander’s verified professional win total includes his MLB debut victory on April 6, 2025, against the Athletics, two additional wins during his 2026 campaign, and six minor league wins in 2024 between Spokane and Hartford, for a confirmed total of at least nine victories across the minors and majors.
Major League Highlights
In his first major league start, Dollander earned the win after allowing four runs on seven hits with six strikeouts over five innings against the Athletics. He added two more wins during the early portion of the 2026 season across 10 appearances. Across his MLB career through mid-2026, he has compiled a 5–15 record with a 5.70 ERA and 129 strikeouts, reflecting both the steep learning curve of a young pitcher and the difficulty of pitching in a tough environment.

Chase and Hunter have two other siblings, making baseball a shared thread through the household.
Personal Life
Tyler Chase Dollander grew up in Evans, Georgia, and has continued to keep his personal life largely out of the public eye as he focuses on his professional career. Public information about romantic partners, marital status, or children has not been confirmed.
2025 Season Performance
The 2025 season marked Chase Dollander’s first full year in the major leagues, and it was a learning experience in every sense. He opened the year in Triple-A Albuquerque before earning a promotion on April 6, debuting that afternoon with a win over the Athletics. The early sample showed flashes of the swing-and-miss stuff that made him a top prospect, including six strikeouts in his first five innings of major league work.
Setbacks shaped the rest of his year. A right forearm tightness issue sent him to the injured list in May, and after a July option to Albuquerque, he returned in August before a left patella tendon strain ended his season in mid-September. His final 2025 line of 2–12 with a 6.52 ERA across 21 starts reflected the difficulty of adjusting to major league hitters, even as the Rockies publicly expressed confidence in his long-term outlook.
With a winter to refine his mechanics and pitch efficiency, the Rockies opened 2026 by transitioning Dollander to a bullpen role, and he responded with a 3.89 ERA across his first 10 appearances before a right elbow injury interrupted his progress. The announced need for UCL surgery cast uncertainty over the rest of his 2026 season, though the organization has continued to list him as part of its long-term pitching plans.
