On Friday, Baseball America published a spotlight of 25 prospects who’ve added significantly to their exit velocities in 2026. At the bottom of the post is a list of all 162 prospects in baseball who added at least 2mph to their 90th percentile exit velocity between last season and this one. The 90th percentile is an important metric, because almost all softly hit balls go for outs, and it’s how hard a batter’s hard hit are that mostly separate sluggers from slap hitters.
Nine Jays prospects made
the list (in addition to Arjun Nimmala, who’s an Angel now but probably owes his gains to work done while he was with the Jays organization). Only the Cardinals (11) and Dodgers (10) has more of their batters add major strength this year. The team has invested a lot in their strength and conditioning program as part of the redevelopment of the Florida complex, and that seems to be paying off. They’ve been singled out as a top organization in that area by multiple prospect experts, most recently Fangraphs’ Brendan Gawlowski. Below, I’ve briefly profiled each of the nine players who made a jump.
The AA Sluggers: Aaron Parker and Jace Bohrofen
Each added a bit more than 3.5mph, with Parker jumping from 106.7mph to 110.4 and Bohrofen from 105.4 to 109.3. Those are big numbers. BA’s Eli Ben-Porat looked into MLB players’ 90th percentile exit velocities in the 2023 seas on to develop rules of thumb for translating the numbers into power scouting grades. He found that most big leaguers cluster around 104mph, making that a 50 on the 20-10 scale. Each mile per hour is a half grade (5 points). 110mph is an 80, the top of the scale. It’s the land of Yordans Alvarez and Aarons Judge. Parker crushes the ball, and Bohrofen is just behind him in the realm of Bryce Harper, Mike Trout, and, well, Vlad.
Neither player is a top prospect in spite of all that juice, however, because of issues with their approaches and contact ability. Parker got the bat on the ball just under 67% of the time this season, while Bohrofen managed an abysmal 62%. Both represent 20 grade contact, and would surely go down farther against MLB calibre pitching. They each take some walks, but that’s more a factor of wild AA pitching than particularly strong plate discipline.
Both players, then, have an exciting carrying tool but will need major strides in the other aspects of hitting to be able to use it at the top level.
Getting to Average: Dub Gleed, J.R. Freethy, Nick Goodwin, Alexis Hernandez and Jean Joseph
All of these players jumped from between 101 and 102mph to between 104 and 105, or 30-35 to 50 on the scouting scale. Gleed and Freethy were both later picks in the 2024 draft, with the former going to the Marlins in the 9th and the latter the Blue Jays in the 14th. Gleed was eventually the trade return for Leo Jimenez when he was squeezed off the 40 man roster this spring. Goodwin was drafted one year earlier. All three are infielders in the upper minors with above average contact skills, solid approaches, and no slam dunk position. With 35 level raw power that profile is just above an org player, the kind of guy who gets hidden on the back half of a AAA roster. With average power, they have a shot to fit as bat first bench infielders that can add a little actual value in MLB. It’s not a thrilling profile, but you need players of this type. 25 different players took a PA for the Jays this past season. When the time comes, it’s nice to have a player who can offer a little pop at the back of the lineup.
Hernandez is a deep, deep sleeper. He was acquired from the Red Sox in the AAA portion of the 2023 Rule 5 draft, which is typically mostly a way to fill out organizational role players. He’s spent the last three seasons slowly climbing the ladder, culminating in a month at AA this past year. He raised his 90th percentile EV from 102.5mph to 104.9 this season, to solid average. Combined with a swing that generates a lot of line drives up the middle, solid contact numbers and a semblance of an approach, that allowed him to put up a career best 132 wRC+. He’s not a major prospect by any stretch, and you have to take a 23 year old’s results against mostly 21 year olds in A+ with a grain of salt, but a guy who plays all three outfield positions and has some offensive tools is worth noting. This season moves him from firmly an org guy to someone who might see an outfield call up if he can consolidate his improvement with a full season in the upper minors in 2027.
Joseph is younger than the other three, at just 21. He jumped straight to A ball as a teenager in 2024 and has held his own at that level over the past three seasons. After losing some time to injury, he got his first taste of A+ late this year. A .153 BABIP masks a strong performance, as he struck out just 13.6% of the time and launched four home runs and seven total extra base hits in 81 PA. His contact rate took a step forward this season and is now plus. He’s always had a strong approach, and has been noted for some speed in the past (although he moved from centre to primarily right field this year). Pair all that with now average thump, and there are the ingredients for a real player. Keep an eye on him as a breakout candidate next year.
A Young Player Flexing his Potential: Aldo Gaxiola
Gaxiola is a 20 year old who signed as an international free agent out of Mexico without much fanfare in May of 2023. He spent two years in the Domincan Summer League and then last season at the American complex before debuting in real games with Dunedin this summer. It was technically his age 20 season, although with a mid-June birthday he was still among the younger players at the level. That didn’t stop him from posting a 106.9mph 90th percentile exit velocity, which would be comfortably plus at the MLB level. He looks solid and physically mature for his age, but given how young he is there’s potential for 70 or better raw power once he’s fully grown up. Right now, there’s a lot of work for Gaxiola to do if that thump is going to carry him to the major leagues. He chased too much and made too little contact this season, and he’ll need to learn to elevate the ball a bit more to turn his strength into production. As he’s already in the process of moving to first base the offensive bar he has to clear is going to be high. Near-elite raw power is a great cornerstone of a prospect profile, though, and he’ll bear close watching this coming season.
The Top Prospect: Sean Keys
I’ve been beating the drum on Keys all season. He was our #17 prospect entering the season after a decent year at A+, and got a pretty cautious write-up from Matt, noting some issues with swing and miss and defensive limitations that would require him to prove it at every level. Well, prove it he did, launching 14 home runs in just 49 games in a brief stop at AA before producing even better after a promotion to Buffalo. His 165 wRC+ was the best in the entire minor leagues among players who got at least 400 PA. His cameo in MLB went poorly, as he got over-aggressive and posted just a 57 wRC+ with too many strikeouts and few walks. The underlying proof of his talent was still there, though, with great bat speed numbers, a 54% hard hit rate and 10% barrel rate, and a contact rate that stood up surprisingly well to top level pitching. His 107.1mph 90th percentile EV is just confirmation of all that then: he upped his power from solid average to easy plus while retaining the ability to make enough good quality contact for it to play. He’ll need to continue to refine his approach, but I’m a true believer and think he’ll hit enough to be a solid regular even at first base or DH.
