Bryan Woo reached 500 career innings pitched on July 7, 2026, marking a significant early-career threshold for the Seattle Mariners right-hander in his fourth major league season.
Across his MLB career as a whole, Woo has appeared in 88 games, posting a 35-21 record with 494 strikeouts, no saves, and a 3.42 ERA over 500 innings pitched.
Woo has spent his entire career with Seattle, appearing in 18 games in 2023, 22 in 2024, and 30 in 2025 before continuing into the 2026 season.
Through 17 starts in the 2026 season, Woo carries a 7-6 record with 97 strikeouts and a 4.17 ERA across 99.1 innings, with a WHIP of 1.03. With just six strikeouts separating him from 500 career Strikeouts, that milestone could reach fruition this season.
The 500-innings-pitched mark represents four seasons of major league service for Woo, who debuted in 2023 and has built his career entirely within one organization.
