Toronto Blue Jays Top Prospects to Know

You are reading the free version of the Toronto Blue Jays Top Prospects. In this version, you will get the full writeups on the top prospect in the system, the biggest sleeper, and a player I could see breaking out in 2025.

In this edition, you will see what I offer in the full team reports. For every farm system, you will get my top 50 ranked players and detailed reports on the top 30. Each report includes advanced player data, traditional scouting thoughts from live and video looks, plus thoughts from scouts around the league.

Let’s dive in on what you get in the full report!

Glossary:

FFG = Future Fantasy Grade - essentially, what is the likely long-term outcome for the prospect? This is always going to be more conservative. Handing out ace tags is not something I like to do. So, this is a realistic outcome.

90th Peak = If the player hits their best-case outcome, what does it look like?

Variance = How risky is this player’s profile, and how likely are they to hit their likely outcome? Low variance is good; high means more risky.

Toronto Blue Jays Top Prospect

1. Ricky Tiedemann, LHP, 22, 6’4”/220, AAA

From a pure upside standpoint, few pitching prospects can compete with the upside Tiedemann brings. Armed with a strong arsenal of three plus or better pitches from the left side, hitters struggle to put the bat on the ball, but for Tiedemann, it’s all about staying healthy. He pitched just 17 innings in 2024 before needing Tommy John surgery.

Tiedemann has a quick arm and throws from a low release height(5’10” on the fastball), creating a very low VAA, which makes tough spots for hitters. It sits in the mid-90s, but Tiedemann has been up to 99 mph in shorter stints with a ton armside run. The IVB is average or slightly below average, but the pitch plays as a plus due to velocity, and 12-15 inches of arm side runs consistently.

The changeup is sold by Tiedemann, maintaining consistent arm speed on both the fastball and changeup. It often sits in the mid-80s with over 20 inches of fade, generating a ton of swing and miss. He does throw it from a release point about five inches lower than his fastball.

The sweeper is probably Tiedemann’s best pitch, though the arsenal is impressive. Sitting in the low-80s, it shows late depth and gets a ton of horizontal movement. Tiedemann spins it well and has consistently generated high whiff rates on the offering.

There is no denying the upside of Tiedmann, as he has one of the best arsenals in all of baseball. The biggest thing will be proving health. With the Tommy John surgery, Tiedemann had another issue in his elbow cleaned up. He is reportedly throwing again, but considering that he had Tommy John on July 30, he may not pitch in 2025.

Toronto Blue Jays Sleeper Prospect

7. Josh Kasevich, SS, 24, 6’2”/200, AAA

In a world where some teams emphasize hit tool and glove value, it is surprising to see Kasevich fly so under the radar. Kasevich has one of the more advanced hit tools in the Minors, posting a contact rate of 90 percent, with an insane 95 percent in-zone mark. There is not a pitch type he struggles to put the bat on either.

Kasevich is no slouch when it comes to hitting the ball hard, either. His 90th percentile exit velocity of 103.5 mph is right at MLB average, and his 89.5 mph average exit velocity is also solid. The biggest issue is a nearly 50 percent ground ball and all-fields approach. While that is not necessarily bad, it limits his home run output, which is why Kasevich hit just six home runs in 2024.

He brings a selective approach, not chasing often and rarely swinging and missing. But to this point in his professional career, 82 percent of Kasevich’s hits have been singles. I believe there is more to unlock here, and the profile is fascinating, especially when you factor in good food speed and solid ability at shortstop. Kasevic could blossom in 2025, and I would not be surprised.

Toronto Blue Jays 2025 Breakout Prospect

8. Kendry Rojas, LHP, 22, 6’2”/190, A+

After signing for $215k in 2020, injuries have limited Rojas significantly. Before 2023, Rojas had thrown just 63 innings. Rojas rebounded in 2023, but a shoulder injury caused him to miss two months of 2024. He returned and posted a 2.43 ERA across 55.2 innings with a 27 percent strikeout rate and a minuscule 5.3 percent walk rate.

Rojas saw a considerable velocity tick up this year, especially before the injury. He went from sitting 92-93 mph to consistently sitting 93-95 and topping out at 97. Rojas has filled out his frame and added weight since last season, so it is no surprise to see him with added velocity. It has cut-ride characteristics at times and was his go-to pitch in 2024.

In addition to the fastball, Rojas has a devastating changeup with late drop and fade, generating plenty of whiffs. The slider is more of a gyro shape in the mid-80s, and Rojas even added an upper-80s cutter this year.

Rojas has thrown strikes at an extremely high clip, with a mark at 69 percent, and pairs it with a swinging strike rate near 17 percent. The frame is that of a starter, and considering the strike-throwing plus arsenal, Rojas looked primed for a breakout. After the All-Star break, Rojas averaged six innings per start and went seven twice. He could be in the Blue Jays rotation by 2026.
