Toronto Blue Jays place Trey Yesavage on injured list with knee inflammation

Aug 5, 2026 | 11:31 AM

TORONTO — The Toronto Blue Jays have placed pitcher Trey Yesavage on the 15-day injured list with left knee inflammation.

The 23-year-old right-hander left Toronto’s 7-2 road loss to the Houston Astros on Tuesday after throwing 16 strikes over two innings. His left knee appeared to buckle as he warmed up for the third inning, and he was checked by a trainer before exiting the game.

Manager John Schneider said after the loss that Yesavage was feeling a pinching sensation in his knee that kept him from balancing.

He came into the game 5-5 this season with a 3.65 earned-run average over 18 starts.

Toronto bolstered its bullpen on Wednesday, claiming Matt Waldron off waivers from the San Diego Padres.

The 29-year-old right-hander has struggled in San Diego this season, putting up a 7.16 ERA over 10 games and going 1-2 across his three starts.

The six-foot-two, 185-pound Waldron made his MLB debut with the Padres in 2023 and has played 46 games for San Diego with a 5.19 ERA, a 20.1 per cent strikeout rate and a 6.8 per cent walk rate.

The Blue Jays also optioned pitcher Chad Dallas to Triple-A Buffalo on Wednesday, and called up right-handers Lazaro Estrada and Chase Lee ahead of a rematch with the Astros in Houston.

Meanwhile, struggling Jays slugger Vladimir Guerrero Jr. was left out of Wednesday’s starting lineup because of fatigue, not injury, Schneider said. Kazuma Okamoto started at first.
