Grant Holmes Bio
Harrison Grant Holmes, known professionally as Grant Holmes, is an American professional baseball pitcher for the Atlanta Braves of Major League Baseball (MLB). He was selected by the Los Angeles Dodgers in the first round of the 2014 MLB draft and spent several years developing through the minor leagues before reaching the majors. Holmes made his MLB debut with the Braves in 2024 and has since emerged as a contributing member of the team’s pitching staff. His professional journey spans three organizations and more than a decade of competitive baseball.
Through the 2026 season, Holmes has compiled a 10-14 win-loss record with a 3.93 earned run average and 258 strikeouts in his major league career with Atlanta. He wears jersey number 66 for the Braves and continues to build on a path that began as one of the most anticipated pitching prospects in his draft class.
Early Life and Background
Harrison Grant Holmes was born on March 22, 1996. He grew up in the United States and developed his baseball skills in the Southeast, attending Conway High School in Conway, South Carolina. While at Conway, Holmes established himself as a premier high school pitching prospect, drawing national attention for his combination of size, arm strength, and poise on the mound. His performances in amateur circuits placed him among the most closely followed arms in his draft year.
By the time he finished high school, Holmes was widely regarded as one of the top pitching prospects eligible for the 2014 Major League Baseball draft. He had committed to the University of Florida, intending to continue his baseball career at the collegiate level before his professional plans changed. His rapid rise through the amateur ranks reflected years of dedicated training and a strong foundation in the fundamentals of pitching.
Path to Baseball
Holmes’ path to professional baseball accelerated dramatically during his senior year of high school. Evaluators consistently ranked him among the elite arms available in the 2014 draft, with several outlets projecting him as a potential first-round selection. The combination of his raw talent and competitive resume made him a target for organizations seeking high-upside pitching.
On draft night, the Los Angeles Dodgers selected Holmes in the first round with the 22nd overall pick, validating his status as a top-tier prospect. Rather than attend the University of Florida, Holmes signed with the Dodgers on June 17, 2014, for a $2.5 million signing bonus. The agreement launched his professional career and set the stage for a long developmental journey through the minor leagues.
Grant Holmes Career
Early Career (2014-2015)
The Dodgers assigned Holmes to the Arizona League Dodgers to open his professional career. In seven appearances with the rookie-level affiliate, he posted a 1-2 record with a 3.00 ERA before earning a midseason promotion to the Ogden Raptors on August 14, 2014. Across four starts with Ogden, Holmes went 1-1 with a 4.91 ERA, gaining valuable experience against older competition.
Holmes returned to full-season ball in 2015 with the Great Lakes Loons, where his performance drew strong reviews. He earned a selection to the midseason All-Star team and finished the year with a 6-4 record and a 3.14 ERA in 24 starts. The season positioned him as one of the more promising arms in the Dodgers’ farm system heading into the next year.
Oakland Athletics Era (2016-2022)
On August 1, 2016, the Dodgers traded Holmes, Jharel Cotton, and Frankie Montas to the Oakland Athletics in exchange for Rich Hill and Josh Reddick. Oakland assigned him to the Stockton Ports to finish the year. In 26 combined games and 23 starts between Rancho Cucamonga and Stockton, Holmes posted an 11-7 record and a 4.63 ERA. The trade marked the beginning of a long developmental chapter with the Athletics.
Holmes spent the 2017 season with the Midland RockHounds, where he logged an 11-12 record with a 4.49 ERA and 150 strikeouts in 148 and one-third innings. On November 20, 2018, Oakland added him to the 40-man roster to protect him from the Rule 5 draft. In 2019, he split time between Midland and the Las Vegas Aviators, going a combined 6-5 with a 3.23 ERA and 81 strikeouts across 86 and one-third innings. Holmes did not appear in a game in 2020 after the minor league season was canceled because of the COVID-19 pandemic. In 2021, he pitched for Triple-A Las Vegas and posted an 8.01 ERA in 36 appearances. On April 1, 2022, Oakland sent him outright to Las Vegas and removed him from the 40-man roster, and the organization released him on July 28, 2022.
Atlanta Braves Era (2022-Present)
On August 13, 2022, Holmes signed a minor league contract with the Atlanta Braves organization and made three appearances between the Florida Complex League Braves and High-A Rome Braves to close out the year. In 2023, he spent the season with the Triple-A Gwinnett Stripers, appearing in 50 games and registering a 7-3 record and a 3.54 ERA with 74 strikeouts and 13 saves across 61 innings. He elected free agency on November 6, 2023, before re-signing with Atlanta on a new minor league deal on November 22, 2023.
In 18 games for Gwinnett in 2024, Holmes posted a 2.63 ERA with 51 strikeouts and 4 saves. On June 16, 2024, Atlanta selected his contract and promoted him to the major leagues for the first time. He made his MLB debut later that day against the Tampa Bay Rays, pitching three scoreless innings in relief with two strikeouts. On July 29, Holmes made his first career start against the Milwaukee Brewers, allowing one run in five innings while striking out eight in a no-decision. He closed the 2024 season with a 2-1 record, a 3.56 ERA, and 70 strikeouts across seven starts.
Holmes continued his growth with Atlanta in 2025. On June 15, 2025, he set a personal best with fifteen strikeouts in a single game. Across 22 appearances and 21 starts, he compiled a 4-9 record and a 3.99 ERA with 123 strikeouts over 115 innings. On July 27, he was placed on the injured list with right elbow inflammation and later transferred to the 60-day injured list, ending his season. Holmes was subsequently diagnosed with a partially torn ulnar collateral ligament and announced plans to attempt rehabilitation without surgery.
Driving Style and Strengths
Holmes has built his major league profile around a power-pitching approach that produces swings and misses in bunches. His ability to miss bats was highlighted by his fifteen-strikeout performance in June 2025, and he has consistently ranked among the team’s leaders in strikeouts per nine innings. Working in both relief and starting roles, Holmes has shown the versatility to handle high-leverage situations and longer outings, providing Atlanta with a flexible option on the mound.
Notable Events and Milestones
Holmes’ MLB debut against the Rays on June 16, 2024, marked the culmination of a ten-year journey through the minor leagues. His fifteen-strikeout game in 2025 stands as his most dominant single outing at the major league level, while his first career start against the Brewers showcased his ability to translate his swing-and-miss stuff into a starting role. The decision to attempt rehab rather than surgery for his UCL injury represents another defining moment in his career arc.

2025 Season Performance
Grant Holmes opened the 2025 season with the Atlanta Braves, building on the momentum of his late-2024 debut. Across 22 appearances and 21 starts, he went 4-9 with a 3.99 ERA and 123 strikeouts over 115 innings of work. His fifteen-strikeout performance on June 15, 2025, against an opponent set a new personal benchmark and stood as one of the most dominant single outings by any pitcher in the National League that season.
Holmes’ season was interrupted on July 27, when right elbow inflammation led to a placement on the injured list. He was transferred to the 60-day injured list the same day, officially ending his 2025 campaign. The subsequent diagnosis of a partially torn ulnar collateral ligament raised questions about his immediate future, but Holmes indicated his preference to attempt a rehabilitation program rather than undergo surgery. The approach reflected his commitment to returning to the Braves’ rotation once healthy.
Looking ahead, Holmes remains under the Braves organization as he works through his recovery. His strikeout totals, his personal-best fifteen-K performance, and his growing role in Atlanta’s pitching staff underscore a player whose career arc continues to trend upward despite the injury setback. His ability to contribute both as a starter and in relief gives the Braves a versatile arm to build around in future seasons.
