With the Toronto Blue Jays’ playoff odds sitting at single digits as of the present day, it’s becoming more and more likely that the playoff dreams are slowly becoming a fantasy.
The special feeling of the 2025 season is gone, and the pain of 2024 doesn’t come close to the pain of this season. With less than two months remaining, the Jays are getting closer to throwing in the towel and seeing what they have in some of their MLB-ready prospects who have yet to make their debut.
There have been a handful of prospects to make debut this season, such as Sean Keys, Brandon Valenzuela, Chad Dallas, CJ Van Eyk, and Yohendrick Piñango, just to name a few. That said, who are a few more prospects who could get a look with the Blue Jays toward the end of the 2026 season?

Josh Kasevich

After 100 games played this season for the Triple-A Buffalo Bisons, Josh Kasevich’s play may be enough to force the Blue Jays to call him up.
This season, Kasevich is slashing .298/.383/.395, with four home runs and 41 RBIs on the season. Since the end of June alone, He has been batting.400 and hitting three of his four home runs. Paired with a strong Spring Training, he could be the first to get a call-up whenever the Blue Jays waive the white flag.
Kasevich has spent the season playing around the infield, playing shortstop, second base, and third base. He currently ranks as MLB Pipeline’s 14th-best prospect in the Blue Jays’ farm system, and could potentially see a call-up depending on Vladimir Guerrero Jr.’s health.
In that scenario, Kazuma Okamoto would move to first base and Kasevich could get a long look at third. Additionally, he could get a look in September if the Jays wish to rest Andrés Giménez or Ernie Clement. Kasevich’s call-up is a bit more murky with the acquisition of Josh Smith at the trade deadline and Luis Urías’ health. On top of that, the Jays would have to add Kasevich to the 40-man roster, meaning a roster move.
That said, it’s best to see what they got in the 2022 draftee.

Ricky Tiedemann

Ricky Tiedemann was once upon a time penciled in to be a front-line starter in the Blue Jays’ rotation. A rapid ascent in 2022 led to him being the team’s best prospect in 2023 and 2024, but then injuries took over.
While his 2023 season was hindered due to injury, he still managed to played a significant number of games that season, but only appeared in a handful of games in 2024 before undergoing Tommy John surgery in the summer of 2024. That led to him missing the rest of the season and all of 2025. Then he was shut down in Spring Training and had a stop-and-start season which also included a neck as well as a should injury.
Finally, Tiedemann has returned to the Bisons after a few rehab outings and has looked good. Injuries are why he’s fallen in the Blue Jays’ top prospect lists, as the stuff is still pretty darn good. His high-90s fastball plays particularly well out of the bullpen, and he still has excellent secondary stuff. Command is also less of a concern out of the bullpen.
For Tiedemann, staying healthy is important, either moving to a full-time bullpen role or another look at starting, which would happen in 2027. But for now, the Blue Jays could use another southpaw in the bullpen as Mason Fluharty is overworked and Brendon Little’s command is still shaky at best.
Already on the 40-man roster, Tiedemann may get a look in September when the rosters expand if he can stay healthy, not just alleviating Fluharty’s work load, but also serving as a try out for 2027.

Jay Harry

Jay Harry has quietly broken out in a big way. Acquired in the Trevor Richards trade before the 2024 deadline, Harry has mediocre numbers to end that season, and was a below-average hitter in 2025. Something has clearly changed in 2026.
The utility player is ranked as the 21st-best Blue Jays’ prospect by MLB Pipeline and has been red-hot throughout the season.  He began the season in Double-A, but has remained hot since joining the Bisons in mid-June. Since the promotion, Harry is slashing .303/.368/529 with an OPS of .898 in 29 games this season in Buffalo.
It’s worth noting that Harry is currently on the 7-day injured list with an undisclosed injury. But if he is back to full health this season, Harry offers more than just a red-hot bat. The 24-year-old left-handed batter also has the position flexibility to move around the infield, as well as being capable of playing in all three outfield spots.
Throughout the years, the Blue Jays have loved positionally versatile players, as well as contact hitters. Harry fits both categories. Rule 5 eligible, it may be worth it to get a look at Harry on the big league roster before the end of the season just to see what they have, that is assuming he returns from injury in 2026. It should be easy to find him a spot in the lineup every day thanks to the versatility.
