Which Blue Jays Prospects Made Just Baseball’s New Top 100?

As spring training gets underway and continues on, there are quite a few names to keep an eye on for Toronto Blue Jays fans. More specifically, there are a few key players to look out for as we dive deeper into Just Baseball’s Top 100 Prospect list.

The Blue Jays’ farm system has taken quite a hit over the years and was just ranked as one of the game’s weakest in the not-so-distant past. However, their latest contention window has magically gone hand-in-hand with a serious strengthening of their minor league ranks.

As the club looks to return to the World Series for the second straight season, its decision makers can at least rest easy knowing that there’s a ton of legitimate talent climbing the organizational depth chart. While some are still years away from being contributors, there are also a handful of them that are ready to make an immediate MLB impact.

95. Arjun Nimmala – SS

Height/Weight: 6’0″, 185 | Bat/Throw: R/R | 1st Round (20), 2023 (TOR) | ETA: 2027

HIT	PLATE DISC.	GAME POWER	RUN	FIELD	FV
40/45	45/55	45/55	55/55	45/55	50

Drafted out of high school back in 2023, Arjun Nimmala has had an inconsistent start to his minor league career, but he has shown he’s still got a ton of potential. After a brief nine-game stint in 2023, Nimmala’s 2024 started off in Single-A Dunedin, but as an 18-year-old, he struggled immensely, slashing .167/.280/.306 while striking out 43 times in his first 29 games.

On May 14, he was sent to the Development List and, two weeks later, assigned to the FCL, before returning to Dunedin on June 27. Nimmala would enjoy a much better second half of his season, slashing .265/.331/.564 over his final 53 games (and 236 plate appearances), while also hitting 15 home runs. Plate discipline remained an issue, however, as he struck out 113 times in Single-A, but his K% dropped post-demotion from 34.4% to 29.7%.

In 2025, Toronto remained aggressive with Nimmala, starting him in High-A Vancouver, and he spent the whole season with the Canadians. Things seemed to continue strongly from 2024, as Nimmala slashed .289/.372/.528 from April-May (with a much more respectable 17.9 K%), whilst mashing nine homers.

Things then took a significant turn.

Nimmala hit .184/.277/.290 the remainder of the season, finishing with a rather pedestrian .224/.313/.331 line, but there were some positives to take away. His power was still there (17 home runs, albeit nine of them were before June 1), his strikeouts dropped, and he grew more comfortable stealing bases, going 17-for-20 on the season, including 8-for-8 in the month of July.

At only 20 years of age, there isn’t much of a rush to bring Nimmala to the majors any time soon, but a bump to Double-A could be an important test on whether he has a chance at sticking around as a top prospect. The skills are there; he just has to prove that he can do it consistently.

61. Joseph “JoJo” Parker – SS

Height/Weight: 6’2″, 190 | Bat/Throw: L/R | 1st round (8), 2025 (TOR) | ETA: 2028

HIT	Plate Disc	GAME POWER	RUN	FIELD	FV
40/55	45/55	35/50	50/50	40/50	50+

JoJo Parker was the fourth high school shortstop taken in the 2025 draft, and as you can see from his above scouting grades, there’s a lot to like.

A .465 hitter in his sophomore year of secondary, there aren’t a ton of stats available to use as he’s yet to make his professional debut; however, he is only 19. Toronto’s approach to Parker will likely mimic that of Nimmala, but the upside with Parker might be a bit higher.

Offensively is where Parker is going to do his damage. He’s got a strong left-handed swing and has the potential to make a ton of hard contact. There’s a chance he ends up a 20+ home run hitter, and he’ll definitely be a fun watch at the plate this season.

At 6-foot-2, Parker is a big body at shortstop, and grades out pretty average in terms of speed. Defensively, he ranks a little bit lower than Nimmala, so the long-term plan could be a move elsewhere in the infield (his strong arm might indicate an eventual transition to third).

We’ll see where Parker starts out in 2026, but it wouldn’t be surprising to see him with Dunedin once spring training ends. If the bat translates at that level, it wouldn’t be a surprise if he jumped a couple of levels this summer.

14. Trey Yesavage – RHP

Height/Weight: 6’4″, 230 | Bat/Throw: R/R | 1st Round (20), 2024 (TOR) | ETA: 2025

FASTBALL	SLIDER	Splitter	COMMAND	FV
55/55	60/60	70/70	45/50	55+

What more is there to say about Trey Yesavage? After starting the year with Dunedin, Yesavage not only found himself pitching in the World Series but also breaking records. Pretty crazy to think that a guy who recorded 39 strikeouts in 27.2 postseason innings is eligible for a Rookie of the Year Award in the following season.

As mentioned, the Blue Jays worked Yesavage up one level at a time, and as the season progressed, it became more and more evident that he wasn’t just the future, he was the present. Releasing the ball at a 64-degree arm angle, Yesavage baffled hitters at all five levels, using his lethal combination of fastballs, sliders, and splitters.

Releasing the ball from such high angles provides an additional layer of deception to his pitches. His four-seam fastball, for example, has almost 20 inches of vertical break, which means that the pitch ends up way lower than most hitters expect. It also helps the play of his splitter, which, coming out of his hand, appears similar, resulting in a ton of swings and misses and weak contact.

Primarily used as his putaway pitch (he recorded 32 of his 55 strikeouts using it), batters put up a measly .115 xBA and had a 58.4% whiff rate against it (regular season and postseason combined). The problem was that when it missed, it was usually loud contact, as evidenced by three of the four homers he gave up coming off his splitter. He also utilised a nasty slider (more so against righties), which will continue to be a valuable pitch in 2026.

While he’s yet to make his spring debut, it should come relatively soon. It’s not shocking that Toronto is taking its time with Yesavage, and with the multitude of options the Blue Jays have in their rotation, it’s not much of a concern if he takes a little extra time to ramp back up to game shape. 2025 was a season that will be hard to replicate for Yesavage, but now he’ll get the opportunity to do so over 30+ starts.
