Yesavage was visited by manager John Schneider and Blue Jays training staff at the mound after his knee buckled while warming up for the third inning. He then exited the game after throwing one test pitch and shaking his head, saying he couldn’t continue.
Right-hander Chad Dallas entered to take his place.
The 23-year-old Yesavage was through two scoreless and hitless innings against the Astros, allowing just one hitter to reach base via a leadoff walk.
Yesavage entered the night with a 3.73 ERA and 91 strikeouts through 91.2 innings on the season.
He began the year on the injured list with a shoulder injury and didn’t make his season debut until April 28.
Yesavage has battled inconsistencies at times in 2026 as he tries to recapture the form that saw him blaze a path to the Blue Jays’ major-league roster just in time for the post-season in 2025.
Toronto’s first-round pick in 2024, the East Carolina product threw 14 regular-season innings for the Blue Jays upon his debut last September before covering 27.2 frames in the playoffs.
