Bryan Woo Autographs
Bryan Joseph Woo (born January 30, 2000) is an American professional baseball pitcher for the Seattle Mariners of Major League Baseball (MLB). He made his MLB debut in 2023 and was named to the All-Star Game in 2025.
Growing up, Woo primarily played shortstop and third base. He had a strong arm but was not viewed as a prospect until growing eight inches during high school. He attended Alameda High School in Alameda, California and did not pitch regularly until his junior year. As a senior in 2018, he went 8–2 with a 1.25 earned run average (ERA) while batting .422 as a switch hitter. He was named the player of the year in the West Alameda County Conference Foothill Division by the Mercury News. That summer, he played for the Peninsula Oilers in the Alaska Baseball League. The San Francisco Giants attempted to sign Woo at a scouting event in Alaska, but he chose to attend college.
Woo enrolled at Cal Poly to play college baseball for the Mustangs. Cal Poly was the only program that recruited him as a pitcher rather than a two-way player. As a freshman in 2019, he had a 9.13 ERA over 23+2⁄3 innings. He returned to play for the Oilers that summer and was named the league's top pro prospect. He pitched only 17+2⁄3 innings as a reliever for Caly Poly in 2020 before the season was cancelled due to the COVID-19 pandemic. In 2021, he had a 6.11 ERA over 28 innings before undergoing Tommy John surgery and missing the rest of the season. Woo started six of the 31 games he pitched in college, finishing with a 4–7 win–loss record, one save, a 6.49 ERA, and 89 strikeouts in 69+1⁄3 innings.
