Great diving catch from #BlueJays No. 13 prospect Josh Kasevich, who then doubled up the runner at first. Great reaction, full extension on the dive. Kasevich has a real shot to force his way onto the roster by mid-season. Having a fantastic spring.

Every new Blue Jays season brings with it several debuts, from top prospects to under-the-radar names — and sometimes they can have a massive impact on the team.
Trey Yesavage had the most notable debut of any Blue Jay in 2025. He immediately became a front-of-the-rotation arm upon his arrival in September, then went on to author several historic starts in the playoffs. Would they have even made the World Series without him?
Here are several players who could make their debut for the Blue Jays in 2026.
Josh Kasevich
Kasevich is having a great Spring Training and could crack the Blue Jays Opening Day roster. He’s the organization’s best infield prospect in the upper minor leagues, and that’s relevant considering the lack of depth up the middle on the MLB roster behind the starters.
He’s an injury away from getting called up, even if he starts the year in Triple-A Buffalo. It would be shocking if he doesn’t make his Blue Jays debut at some point in 2026.
Adam Macko
Macko will start the season in Triple-A, yet flashed MLB-calibre upside this spring. The biggest development for the 25-year-old lefty was his fastball velocity; he was consistently sitting above 95 mph.
The Blue Jays could use more left-handed heat in their bullpen. Whether it’s an injury or someone struggling, Macko will probably be one of the first calls if someone is needed — except to see him in 2026.
RJ Schreck
Schreck has been quietly raking in the minor leagues for years now. He recorded a .828 OPS in Triple-A in 2025, suggesting he may be ready for his first cup of coffee at the big-league level with the Blue Jays.
If whoever the team picks as their final bench player come Opening Day—whether it be Eloy Jiménez, Davis Schneider, or someone else—struggles, Schreck could get his shot to prove himself. The organization will want to see what he can do sooner rather than later.
Ricky Tiedemann
Injuries are the main reason Tiedemann has yet to make his Blue Jays debut. He’s thrown just 17 1/3 innings over the last two years combined, and just recently resumed throwing after being sidelined for several weeks with elbow soreness early in spring training.
A healthy Tiedemann could transform the Blue Jays’ bullpen. They need more velocity—especially from the left side—and he’s got that in spades. While he probably won’t be first to make his debut, considering he’s already been optioned to Triple-A, he is probably the most likely on this list to have a Yesavage-esque impact down the stretch.
