Watching prospects grow through the minor-league system is something Blue Jays fans have had under the microscope for some time now.

Last season, fans saw the emergence of players like Addison Barger, Trey Yesavage, Bryadon Fisher, and Mason Fluharty. This year, names like Yohendrick Pinango and Brandon Valenzuela have captured attention. You can now add Adam Macko and Charles McAdoo to that list, as both have made their presence felt on the big-league club in the short time since being recalled from the minors.

Even depth arms like Lazaro Estrada and Tanner Andrews have received some additional time in the big leagues this season. While Toronto has acquired external depth like Connor Seabold and Matt Bowman (on a minor-league contract) over the past few games, the front office is increasingly looking to the farm system to see who is ready for a shot.

So, who is most likely to seize the next opportunity from the internal farm system?

Many Blue Jays fans were impressed by Josh Kasevich during spring training.

The organization’s #13-ranked prospect heading into 2026 has firmly established himself as a reliable option in the middle infield. The 25-year-old shortstop slashed .306/.375/.500 in 20 spring training games, logging a home run and five RBIs. Out of his 11 spring hits, four were doubles, resulting in an impressive .875 OPS. Kasevich also played in the second-most spring training games of any position player, signalling just how much the organization values his development.

In 53 games for the Triple-A Buffalo Bisons this season, Kasevich is hitting .277 with 22 RBIs. He ranks second on the team in doubles (eight) and leads the Bisons in triples (three). The only Buffalo player with more total bases than Kasevich this season is Charles McAdoo, whom the Blue Jays recently recalled.

Defensively, Kasevich has split his time between shortstop and third base, while also serving as the designated hitter for a few games. With Davis Schneider sent down to the minors and Lenyn Sosa struggling (and now injured), the door could open for Kasevich to make his big-league debut sooner rather than later. While Ernie Clement and Andrés Giménez are proving to be more than capable of shouldering the middle infield at second and shortstop, having Kasevich on deck is becoming an increasingly attractive luxury.

While some thought Chad Dallas was going to be joining the big leagues this weekend in Baltimore, given the nameplate debacle, manager John Schneider also mentioned Triple-A right-hander CJ Van Eyk as a name to watch this season.

A 2020 draft pick, Van Eyk was ranked 18th in the Blue Jays’ system in 2024, but many fans had written him off due to persistent injuries. He underwent Tommy John surgery in 2022 and missed a year and a half of development during his recovery.

His first healthy season back came with the Double-A New Hampshire Fisher Cats, where he posted a 5.68 ERA across 30 appearances, striking out 78 batters over 95 innings. In 2025, Van Eyk earned a promotion to Triple-A Buffalo, posting a 4.94 ERA in 20 games. This season, however, Van Eyk has finally found his rhythm, pitching to a much-improved 3.65 ERA across 49.1 innings in 10 games.

Some of his recent success stems from a stint with the Águilas de Mexicali in the Mexican Pacific League this past winter, where he posted a 2.90 ERA and a 25.4% strikeout rate. Van Eyk’s fastball can top out at 95 MPH, and he effectively pairs it with a sharp, sinking curveball to generate chases. Despite a long road of injuries, we could finally see the former high draft pick make his big-league debut six years after being drafted.

With Joe Mantiply on the injured list for the foreseeable future, the Jays have leaned heavily on Mason Fluharty and now Adam Macko as left-handed options out of the bullpen. Because of that injury tax, 29-year-old Michael Plassmeyer is quietly moving up the southpaw depth chart.

Plassmeyer has been spectacular for the Bisons, cruising to a 1.21 ERA across 22.1 innings. He has allowed just three earned runs all year—tying him with Tanner Andrews (who just pitched for the Blue Jays against the Miami Marlins) for the fewest runs allowed on the team among pitchers with at least 20 innings.

Plassmeyer does have major-league experience, though it comes via a very small sample size. In three games across two seasons with the Philadelphia Phillies, he struggled to a 9.82 ERA, surrendering 12 earned runs in 11 innings. While it has been three seasons since he last pitched in the majors, his current minor-league performance warrants another look.

As a bonus, Plassmeyer has a minor-league option remaining, making him a flexible piece for “paper transactions” if the Blue Jays need to shuffle roster spots without risk of losing him on waivers. Stylistically, Plassmeyer relies heavily on generating whiffs and chases to get outs.

While Fluharty and Macko remain the primary left-handed options in Toronto’s bullpen, the chaotic nature of the 2026 season means fans should be ready for just about anything—including a Plassmeyer call-up.
