The Blue Jays selected the contract of right-hander Chad Dallas on June 4, 2026, and sent Hayden Juenger to Triple-A Buffalo in the corresponding move. To make room on the 40-man roster, Toronto designated Tanner Andrews for assignment.

The call-up gives the Blue Jays another starter to cover innings on a day when they badly needed one. Dallas, 26 later this month, is being added as Toronto leans on a battered rotation that has already lost José Berríos, Cody Ponce and Bowden Francis for the season while Dylan Cease, Max Scherzer, Shane Bieber and Lazaro Estrada remain on the injured list. Jake Bloss is still working back from Tommy John surgery, Ricky Tiedemann is hurt, and the club has been stitching games together with Kevin Gausman, Trey Yesavage and Patrick Corbin, plus frequent bullpen starts and bulk work from Rule 5 pick Spencer Miles. Austin Voth was pulled up for an emergency bulk outing last week before getting bumped off the roster, and Mason Fluharty was technically starting on June 4.

For Dallas, this is the first time he has reached the majors. Toronto drafted him in the fourth round in 2021, and he had built a case as a rotation prospect by making 23 starts between High-A and Double-A in 2023, when he logged 123 1/3 innings with a 3.65 ERA, a 27.9% strikeout rate, a 9.5% walk rate and a 44.3% ground-ball rate. Baseball America ranked him as the system’s No. 14 prospect going into 2024, and FanGraphs had him 16th. Then came Tommy John surgery in September 2024, and he missed the entire 2025 season.

Dallas has spent 2026 rebuilding at Buffalo, where he has thrown 36 innings with a 4.50 ERA, a 24.1% strikeout rate, an 8.2% walk rate and a 41.7% ground-ball rate. The Blue Jays have used him as a starter there, but the shape of his role down the road is still open enough to matter. For now, Toronto needs innings, and Dallas is being asked to provide them. The more likely next step is a return to Buffalo after this appearance, but the club has not said how long he will stay in the majors.

Toronto’s pitching crisis gives the move its urgency, but it also explains why Dallas is here at all: the Blue Jays need a live arm now, even if he may fit better later in a relief role. The team acquired Simeon Woods Richardson on June 3, another sign it is working every angle to keep the staff afloat. Dallas gets his first shot because the rotation has run out of safe options, and that is the clearest sign of where the roster stands on June 4.
