Gabrielson has pitched for three seasons at Princeton, logging 37 innings of work over 20 total appearances. He made his first career start during the shortened 2020 season, but has primarily been used out of the bullpen. The Knoxville, Tennessee native was one of the top 50 players in the state coming out of high school, as well as a top-25 righthanded pitcher. Gabrielson is a veteran of the summer ball circuit, playing in 2018 for Wilmington in the Coastal Plain League and in 2019 for the Mystic Schooners of the New England League.
