Zachery Reed Kelly Bio
Zachery Reed Kelly is an American professional baseball pitcher who currently plays for the Boston Red Sox of Major League Baseball. Born on March 3, 1995, Kelly built his career through persistence and resilience, signing with the Oakland Athletics as an undrafted free agent in 2017 before eventually reaching the majors with the Red Sox in 2022. Throughout his professional journey, Kelly has established himself as a reliable relief pitcher, overcoming significant setbacks including multiple elbow surgeries to maintain his role in Major League Baseball.
Early Life and Background
Kelly grew up in Daleville, Virginia, where he attended Lord Botetourt High School. After graduating, he enrolled at Concord University, playing college baseball for the Concord Mountain Lions in NCAA Division II during the 2014 season. As a starting pitcher, Kelly demonstrated promising abilities before making the decision to transfer to Newberry College to continue his baseball career.
At Newberry College, Kelly joined the Newberry Wolves, another Division II program. During his senior season in 2017, he emerged as a standout performer, recording a 3.72 earned run average and accumulating 94 strikeouts across 82 and one-third innings pitched. His strong collegiate career, however, did not result in being selected during the 2017 MLB draft, leading him to pursue an opportunity as an undrafted free agent.
Path to Major League Baseball
Despite going undrafted, Kelly remained determined to pursue professional baseball. He signed with the Oakland Athletics as an undrafted free agent in 2017, receiving a $500 signing bonus. He made his professional debut that same year in the rookie-level Arizona League. The Athletics released Kelly in April 2018, but he quickly found another opportunity.
Kelly signed with the Los Angeles Angels organization shortly after his release from Oakland. He progressed through the Angels’ system, reaching the Class A-Advanced level with the Inland Empire 66ers of the California League during the 2018 season. In 18 relief appearances, Kelly posted an impressive 2.93 earned run average with 41 strikeouts in 43 innings pitched. The following year, he split time between the Double-A Mobile BayBears and Inland Empire, compiling a 3-7 record with a 4.88 earned run average in 21 games.
Zachery Reed Kelly Career
Early Career (2017-2021)
Kelly began his professional career in 2017 with the Arizona League Athletics, playing in the rookie-level league following his collegiate career. He experienced the financial challenges that many minor league players face, later acknowledging that his first professional season resulted in a financial loss. After his release from Oakland in 2018, Kelly found stability with the Angels organization, where he refined his skills as a relief pitcher and steadily climbed the minor league ladder.
The 2020 season brought significant challenges for Kelly. The COVID-19 pandemic forced the cancellation of the minor league season, and during the shutdown, the Angels released him. More critically, Kelly underwent surgery on his elbow to have a ligament reattached, a procedure that threatened his baseball career. His resilience through this setback would become a defining characteristic of his professional journey.
Boston Red Sox Breakthrough (2021-2023)
On January 4, 2021, Kelly signed a minor league contract with the Boston Red Sox organization. That season, he played for both the Double-A Portland Sea Dogs and the Triple-A Worcester Red Sox. Kelly excelled in his role as a relief pitcher, posting a remarkable 1.69 earned run average in 21 relief appearances for Portland before earning a promotion to Worcester, where he recorded a 2.89 earned run average in 15 relief appearances. His dominant performance throughout 2021 earned him an invitation to spring training with the major league club in 2022 as a non-roster player.
Kelly began the 2022 season with Triple-A Worcester and continued his strong pitching. On August 29, 2022, the Red Sox added him to their major league roster. He made his MLB debut that evening against the Minnesota Twins, fulfilling a lifelong dream. In 13 relief appearances during his rookie season, Kelly posted a 1-0 record with a 3.95 earned run average and 11 strikeouts in 13 and two-thirds innings. For his outstanding contributions to the organization, Kelly received the 2022 Lou Gorman Award, presented annually by the Red Sox to a player who demonstrates perseverance, dedication, and love for baseball.
The 2023 season saw Kelly begin the year in Boston’s bullpen, but injuries soon interrupted his progress. On April 13, he was placed on the injured list due to right elbow inflammation, and three days later he was transferred to the 60-day injured list. In May, it was announced that Kelly would miss approximately four months after undergoing a successful ulnar nerve transposition revision in his right elbow. He was activated from the injured list on September 24, 2023, marking an inspiring return after 166 days away from major league competition.
Boston Red Sox Era (2024-Present)
Kelly started the 2024 season with Triple-A Worcester but received a promotion to the major league roster on April 24 when pitcher Brayan Bello was placed on the injured list. He was optioned back to Worcester on May 26 to make room for pitcher Brad Keller but was recalled to Boston’s roster on June 5. A notable moment in his career came on June 9, 2024, when Kelly made his first MLB start as an opener against the Chicago White Sox, pitching two scoreless innings. Throughout the regular season, Kelly appeared in 49 games for Boston, compiling a 6-3 record with a 3.97 earned run average and 61 strikeouts in 56 and two-thirds innings pitched.
