The Blue Jays optioned Lee to Triple-A Buffalo on Friday.
The move makes room on the Blue Jays' 26-man roster for newcomer Matt Waldron. Lee appeared in two games out of Toronto's bullpen after being recalled Wednesday, allowing one unearned run on one hit and one walk while striking out one batter across two frames. He has spent most of the 2026 season in Triple-A, where he has a 2.20 ERA, 1.13 WHIP, five saves and a 40:18 K:BB over 45 innings.
