Overview
- Toronto finalized a minor-league contract with Jesse Hahn, 36, and invited him to major league spring training as a non-roster player, per the official transactions log.
- Hahn returned to the majors in 2025 with the Mariners after a 2021 shoulder injury and three full seasons away, logging five MLB innings with three earned runs.
- The eight-year MLB veteran owns a 19–22 record with a 4.24 ERA across 316 1/3 innings after stops with the Padres, Athletics, Royals and Mariners, and he was a 2010 sixth-round pick by the Rays.
- At Triple-A Tacoma last season, he posted a 5.85 ERA with 34 strikeouts in 32 1/3 innings, generated a 61.8% ground-ball rate, and worked primarily with a 95 mph sinker and a slider.
- Hahn joins a group of veteran relief options as the Blue Jays build bullpen depth behind projected late-inning arms Jeff Hoffman, Tyler Rogers and Louis Varland, with additional non-roster adds such as Josh Fleming, Connor Seabold, Josh Winckowski and Michael Plasmeyer.
