BIOGRAPHY
Zack Kelly was born March 3, 1995, in Roanoke, Virginia. He was a pitcher in the MLB.
Kelly signed with the Los Angeles Angels organization and played for three teams in the Angels' system, reaching the Class A-Advanced level with the Inland Empire 66ers of the California League; in 18 total relief appearances during the season, he posted a 2.93 ERA and struck out 41 batters in 43 innings pitched. Kelly began the 2019 season with the Mobile BayBears of the Double-A Southern League, and also played one game with Inland Empire, accruing an overall 3–7 record in 21 games (13 starts) with a 4.88 ERA. The Angels released Kelly during the COVID-19 shutdown in 2020. Shortly thereafter, Kelly underwent surgery on his elbow to have a ligament reattached.
In 2021, Kelly joined the Red Sox organization, playing for the Double-A Portland Sea Dogs and the Triple-A Worcester Red Sox. He had a 1.69 ERA in 21 relief appearances for Portland before he was promoted to Worcester, where he had a 2.89 ERA in 15 relief appearances. In 2022, the Red Sox invited Kelly to spring training as a non-roster player and he returned to Worcester for the beginning of the season. He accrued a 2.72 ERA for Worcester through August 29, when he was added to Boston's major-league roster. Kelly made his MLB debut that evening, against the Minnesota Twins. He was on the paternity list for three days in early September. In 13 relief appearances with Boston, Kelly pitched to a 1–0 record with 3.95 ERA while striking out 11 batters in 13+2⁄3 innings. Kelly was the 2022 recipient of the Lou Gorman Award issued by the Red Sox organization.
