Grant Holman Bio
Grant James Holman (born May 31, 2000) is an American professional baseball pitcher currently in the Philadelphia Phillies organization of Major League Baseball (MLB). A right-handed pitcher, Holman came up through the Oakland Athletics system after a decorated amateur career that included a Little League World Series appearance. He made his major league debut in 2024 and has since bounced between Triple-A and the big leagues, establishing himself as a depth option with swing-and-miss stuff in the bullpen.
Standing 6 feet tall and known for his mid-90s fastball and sharp slider, Holman has worked as both a starter and a reliever. His combination of a strong work ethic and team-first mentality has made him a respected figure in clubhouses wherever he has played. The Athletics selected him in the sixth round of the 2021 MLB Draft after he starred at Eastlake High School and the University of California, Berkeley.
Early Life and Background
Holman grew up in the Chula Vista area of Southern California, a region that has produced a steady stream of baseball talent. As a young athlete, he showed advanced pitching ability for his age, which earned him a chance to represent his community on a national stage. His early training emphasized mechanics, mound presence, and developing a feel for multiple pitches, all of which helped him stand out among his peers.
When he was just 13 years old, Holman played in the 2013 Little League World Series, where he threw a no-hitter on one of baseball’s biggest youth stages. The performance announced him as a player to watch and gave him valuable experience in high-pressure environments. That summer helped set the foundation for his transition into high school baseball at Eastlake High School in Chula Vista, California, where he continued to develop his craft against strong competition.
Path to Baseball
Holman’s amateur path continued at Eastlake High School, where he was a standout pitcher and a key part of the program’s success. His poise and pitch repertoire drew attention from college recruiters, and he committed to the University of California, Berkeley, to play college baseball in the Pac-12 Conference. The Golden Bears offered him a chance to face top-tier collegiate hitters while refining his arsenal.
During the summer of 2019, Holman played collegiate summer baseball with the Cotuit Kettleers of the Cape Cod Baseball League, one of the most prestigious wooden-bat leagues in the country. Competing against many of the nation’s best college players sharpened his approach and prepared him for the next level. After his junior year at Cal, he entered the 2021 MLB Draft, where the Oakland Athletics selected him in the sixth round with the 188th overall pick.
Grant Holman Career
Early Career (2021–2022)
After signing with Oakland, Holman made his professional debut with the Single-A Stockton Ports, beginning his climb through the minor leagues. The Athletics handled him carefully, focusing on refining his mechanics and expanding his pitch mix against older hitters. He adjusted to the longer professional schedule and the demands of a full minor league season.
In 2022, Holman split time between the rookie-level Arizona Complex League Athletics and the High-A Lansing Lugnuts. Across 41 and two-thirds innings pitched, he posted a 1–5 record with a 4.75 ERA and 40 strikeouts. The season provided important lessons about consistency and durability, setting the stage for his promotion the following year.
Athletics Development (2023)
Holman returned for the 2023 season and was used across multiple affiliates, including the ACL Athletics, Lansing, and the Double-A Midland RockHounds. He logged 35 total appearances, posting a 4.26 ERA with 60 strikeouts, three saves, and 44 and one-third innings of work. Moving between the bullpen and the rotation, he showed he could handle varied roles.
His performance earned him an invitation to major league spring training, and the Athletics added him to the 40-man roster ahead of the 2024 season. The promotion reflected the organization’s growing belief in his ceiling as a power arm out of the bullpen.
Major League Debut with Oakland (2024)
Holman opened 2024 with Double-A Midland, dominating hitters with 17 scoreless appearances that included 24 strikeouts and six saves. That success led to a promotion to the Triple-A Las Vegas Aviators, where he posted a 0.92 ERA with 30 strikeouts across 23 appearances. The combination of dominance and durability made him a clear candidate for a big league call-up.
On August 16, 2024, the Athletics selected Holman to the 40-man roster and promoted him to the major leagues for the first time. In 18 appearances for Oakland that season, he went 1–1 with a 4.02 ERA and 16 strikeouts over 15 and two-thirds innings. The stint confirmed he could compete against major league hitters.
Athletics Bullpen Role (2025)
Holman was optioned to Triple-A Las Vegas to begin the 2025 season, where he continued to work on his secondary pitches. The Athletics recalled him on April 23, 2025, and he became a regular in the major league bullpen. In 22 appearances, including two starts, he went 4–2 with a 5.09 ERA and 17 strikeouts over 23 innings.
On June 16, 2025, Holman was optioned back to Las Vegas after J.T. Ginn was activated from the injured list. Three days later, his option was rescinded, and he was placed on the injured list with rotator cuff tendinitis. On July 15, the club transferred him to the 60-day injured list, pausing his development for the rest of the year.
Driving Style and Strengths
Holman features a mid-90s fastball with riding life and a sharp slider that serves as his primary swing-and-miss pitch. He works aggressively in the strike zone and thrives in high-leverage relief situations, where his strikeout ability plays up. His willingness to attack hitters and his calm mound presence make him a reliable late-inning option when healthy.
Notable Events and Milestones
Holman’s 2013 Little League World Series no-hitter remains one of the signature achievements of his amateur career. Reaching the major leagues in 2024 marked another milestone, as did his dominant 2024 minor league campaign that featured 17 consecutive scoreless appearances at Double-A. He also became a valuable piece of the Athletics bullpen during the 2025 season before his injury setback.
Grant Holman Career Wins
Holman has built a steady record of success across the minors and majors, highlighted by his dominant 2024 stretch at Double-A and Triple-A. His major league work with Oakland included a 5–3 record overall across the 2024 and 2025 seasons, paired with 33 strikeouts in his early big league innings. While he has not yet established himself as a full-time closer, his late-inning experience points to that potential in the future.
Oakland Athletics Highlights
Holman’s first major league victory came during his 2024 debut season with Oakland, a memorable moment that validated his long climb through the system. In 2025, he added four more wins across 22 appearances, including two starts, before his rotator cuff injury. His most recent big league outing came in June 2025 before he was placed on the injured list.
Other Wins and Performances
Beyond the majors, Holman has posted strong numbers at every minor league stop, including his standout 0.92 ERA at Triple-A Las Vegas in 2024. His 17 scoreless appearances at Double-A Midland that same year underscored his ability to dominate experienced hitters. These performances cemented his reputation as a rising bullpen arm within the Oakland organization.

Family Background and Racing Lineage
Holman comes from a supportive family in the Chula Vista area of Southern California, where youth baseball is a central part of community life. His family backed his development from Little League through high school and college, helping him chase his dream of playing professionally. While specific family details are not widely documented, Holman has often credited his parents for keeping him grounded throughout his journey.
Personal Life

He maintains an active social media presence and engages with fans through updates about his career. As of the most recent reports, he remains unmarried and continues to dedicate himself to his craft as a professional pitcher.
2025 Season Performance
Holman’s 2025 season began in Triple-A Las Vegas before his April 23 recall to Oakland, where he quickly became a key bullpen piece. Through 22 appearances, including two starts, he recorded a 4–2 record with a 5.09 ERA and 17 strikeouts across 23 innings. His ability to eat innings in long relief gave the Athletics flexibility during a transitional stretch of their schedule.
His campaign was cut short in mid-June, when he was placed on the injured list with rotator cuff tendinitis and later transferred to the 60-day IL on July 15. The injury limited his opportunities to build on his promising 2024 debut and forced Oakland to rely on other bullpen arms down the stretch. Recovery and rehabilitation will be a key focus for Holman during the offseason.
