## Amateur career
Holman played in the 2013 [Little League World Series](https://www.edgepedia.org/little-league-world-series) with his Eastlake team from Chula Vista and threw a no-hitter with 13 strikeouts in a 3-0 win against a team from Michigan; MLB's biographical notes identify him as the first pitcher since 1979 to throw an extra-inning no-hitter in the Little League World Series.[1](https://www.mlb.com/athletics/player/grant-holman-680880) At Eastlake High School his teammates included Keoni Cavaco, a 2019 first-round pick, and Marcelo Mayer, a projected top-five pick in 2021.[3](https://www.baseballamerica.com/players/15160-grant-holman/)
At the [University of California](https://www.edgepedia.org/university-of-california), Berkeley, he was a two-way player. As a freshman in 2019 he hit .272/.362/.456 as the designated hitter while making 11 pitching appearances, and on May 4, 2019, at Utah he hit a game-tying grand slam and then pitched the ninth inning for a save.[6](https://img.mlbstatic.com/milb-images/image/upload/milb/zwzfhoavh7ehndal7rg9.pdf) In the COVID-shortened 2020 season he was Cal's starting first baseman and number two pitcher.[6](https://img.mlbstatic.com/milb-images/image/upload/milb/zwzfhoavh7ehndal7rg9.pdf) A hit by pitch in the face against San Jose State on March 10, 2020, ended his college hitting career; he was used exclusively as a pitcher afterward.[1](https://www.mlb.com/athletics/player/grant-holman-680880) • [6](https://img.mlbstatic.com/milb-images/image/upload/milb/zwzfhoavh7ehndal7rg9.pdf) Entering his junior year he was named to the Golden Spikes Award preseason watch list and earned preseason First-Team All-American honors from [Baseball America](https://www.edgepedia.org/baseball-america).[1](https://www.mlb.com/athletics/player/grant-holman-680880) In an injury-hampered 2021 junior season he made 10 weekend starts, throwing 47 innings with a 3.83 ERA, 20 walks, and 46 strikeouts.[6](https://img.mlbstatic.com/milb-images/image/upload/milb/zwzfhoavh7ehndal7rg9.pdf) His three-year Cal line was 5-9 with a 4.05 ERA in 25 games, including 23 starts, with 89 strikeouts in 109.0 innings.[1](https://www.mlb.com/athletics/player/grant-holman-680880) • [7](https://calbears.com/news/2021/7/12/baseball-four-bears-selected-on-day-two-of-mlb-draft)
## Professional career
**Draft and minor leagues.** The Oakland Athletics selected Holman in the sixth round (188th overall) of the 2021 MLB June Amateur Draft and he signed for $375,000.[3](https://www.baseballamerica.com/players/15160-grant-holman/) He pitched at Single-A Stockton in 2021, then spent 2022 and 2023 with High-A Lansing and Double-A Midland while spending time on the injured list several times.[4](https://www.si.com/mlb/athletics/onsi/news/the-oakland-a-s-next-bullpen-weapon-01j1tng0h451) • [1](https://www.mlb.com/athletics/player/grant-holman-680880) Injury concerns pushed him into the bullpen in professional ball.[3](https://www.baseballamerica.com/players/15160-grant-holman/)
**2024 breakout.** Working entirely in relief across Double-A Midland and Triple-A Las Vegas, Holman went 4-0 with nine saves, a 0.55 ERA, and a .480 opponents' OPS in 40 games, allowing just three earned runs in 48.2 innings and one home run.[5](https://pressbox.athletics.com/home%20directory/Publications/Athletics%20Media%20Guides/2025%20Athletics%20Media%20Guide%20Preview.pdf) • [3](https://www.baseballamerica.com/players/15160-grant-holman/) He did not allow a run in 17 relief appearances with Midland and converted all six of his save opportunities there before his June 3 promotion to Las Vegas.[5](https://pressbox.athletics.com/home%20directory/Publications/Athletics%20Media%20Guides/2025%20Athletics%20Media%20Guide%20Preview.pdf) He was named to the Pacific Coast League Postseason All-Star Team and earned A's Organizational Reliever of the Year honors.[5](https://pressbox.athletics.com/home%20directory/Publications/Athletics%20Media%20Guides/2025%20Athletics%20Media%20Guide%20Preview.pdf)
**Major leagues.** Holman debuted with Oakland on August 17, 2024, and finished the season 1-1 with a 4.02 ERA in 18 relief appearances, walking nine in 15.2 innings.[1](https://www.mlb.com/athletics/player/grant-holman-680880) • [5](https://pressbox.athletics.com/home%20directory/Publications/Athletics%20Media%20Guides/2025%20Athletics%20Media%20Guide%20Preview.pdf) In 2025 he appeared in 22 games for the A's, going 4-2 with a 5.09 ERA in 23.0 innings, before a right shoulder rotator cuff tendinitis injury placed him on the injured list on June 19, 2025; he was moved to the 60-day injured list in July and activated on November 5, 2025.[1](https://www.mlb.com/athletics/player/grant-holman-680880) • [8](https://locable-assets-production.s3.amazonaws.com/uploads/resource/file/1278134/PN_2002-27-2026.pdf?timestamp=1772058367)
**2026 waiver moves.** To clear a 40-man roster spot, the Athletics designated Holman for assignment on February 10, 2026.[8](https://locable-assets-production.s3.amazonaws.com/uploads/resource/file/1278134/PN_2002-27-2026.pdf?timestamp=1772058367) He then moved through a series of waiver claims: the [Arizona Diamondbacks](https://www.edgepedia.org/arizona-diamondbacks) claimed him on February 15, 2026, and designated him for assignment on March 25; the [Los Angeles Dodgers](https://www.edgepedia.org/los-angeles-dodgers) claimed him on April 1; the [Detroit Tigers](https://www.edgepedia.org/detroit-tigers) claimed him on April 11 and designated him on May 3; and the Philadelphia Phillies claimed him off waivers on May 7, 2026, optioning him to Triple-A Lehigh Valley.[2](https://www.mlb.com/player/grant-holman-680880)
## Pitching style
Holman throws a three-pitch mix: a four-seam fastball around 95 mph, a slider in the low 80s, and a splitter used as a complement.[4](https://www.si.com/mlb/athletics/onsi/news/the-oakland-a-s-next-bullpen-weapon-01j1tng0h451) Baseball America credits his elite extension from his 6-foot-6 frame with helping his mid-90s fastball play up, with hitters missing it nearly 30 percent of the time in the minors in 2024 despite the pitch's fairly ordinary shape; the A's also had him alter his secondary pitches to add horizontal movement in each direction.[3](https://www.baseballamerica.com/players/15160-grant-holman/) The outlet ranked him the Athletics' number 19 prospect entering 2025 with a 40 grade and medium risk.[3](https://www.baseballamerica.com/players/15160-grant-holman/) A relief role has suited his aggressive approach on the mound.[9](https://www.baseballamerica.com/stories/oakland-athletics-prospects-2024-midseason-top-30-update/)
