As we begin to wind down the 2025 minor league season, players across all levels have well-stabilized data and metrics. This provides us an opportunity to dig in on performance to identify strengths, weaknesses and outliers. What we find is that high-performing players with great underlying data tend to consistently perform at each new level.
Below, we’ve compiled a list of 10 high-profile prospects who have logged some impressive numbers this season in key categories like 90th percentile exit velocity, hard-hit percentage, air-pull percentage and more.
Konnor Griffin, OF, Pirates
| Swing% | Z-Whiff% | Miss% | Chase% | 90%EV | HardHit% | Heart% | PullAir% |
| 46.80% | 16.80% | 25.30% | 24.00% | 109.2 | 49.70% | 76.2 | 16 |
At the time of the 2024 draft, Griffin was viewed as a tooled-up prep talent with some mechanical flaws in his swing and corresponding hit tool questions. In his first full professional season, however, Griffin has silenced those questions with outstanding performance and claimed the No. 1 spot in Baseball America’s Top 100 Prospects ranking.
Despite only being 19 years old, Griffin’s bat-to-ball skills are well above-average with easy plus swing decisions. He rarely expands the zone while remaining aggressive on pitches over the heart of the plate.
While Griffin is still learning to consistently elevate the ball to his pull side, it’s less of a concern due to his elite exit velocity data. Griffin’s 109.2 mph 90th percentile EV is in the top 1% of players in MiLB.
Kevin McGonigle, SS, Tigers
| Swing% | Z-Whiff% | Miss% | Chase% | 90%EV | HardHit% | Heart% | PullAir% |
| 47.00% | 13.40% | 17.50% | 20.40% | 105.8 | 46.80% | 80.1% | 25.8% |
As far as data is concerned, there might not be a better prospect on paper than McGonigle.
Ranked just one spot behind Griffin in the Top 100, McGonigle does everything as a hitter at an above-average or better level. He has elite bat-to-ball skills, discerns balls and strikes as well as any prospect in the minors and shows at least above-average game power. He consistently hits the ball hard at good launch angles and shows the ability to consistently get into his pullside power.
McGonigle boasts a 70-grade hit tool with potentially 80-grade swing decisions and 60-grade power. Based on historical data benchmarks, McGonigle looks like a future superstar in the making.
JJ Wetherholt, SS, Cardinals
| Swing% | Z-Whiff% | Miss% | Chase% | 90%EV | HardHit% | Heart% | PullAir% |
| 41.40% | 15.90% | 20.10% | 17.30% | 103.8 | 48.00% | 77.4% | 14.4% |
For a season in which young, tooled-up shortstops and 2024 draftees have been the talk of the prospect world, Wetherholt is at the intersection of the two storylines. One of the best hitters in the loaded 2024 college class, the 22-year-old is on the cusp of the major leagues and ranked among the game’s best prospects.
Wetherholt has shown his typical bat-to-ball skills and advanced approach this season, though his contact rates have slid at Triple-A. What’s new is his ability to hit the ball hard in the air for home run power in games. While Wetherholt’s 90th percentile exit velocity is on the lower end of the 55-grade bucket, his 48% hard-hit rate is squarely in plus territory. His pullside power is still coming along and will be a limiting factor for Wetherholt’s game power.
Despite any nits you can pick, Wetherholt’s overall hitting data is phenomenal showing a well rounded hitter and a tough out.
Walker Jenkins, OF, Twins
| Swing% | Z-Whiff% | Miss% | Chase% | 90%EV | HardHit% | Heart% | PullAir% |
| 45.70% | 14.10% | 21.00% | 20.80% | 102.4 | 32.70% | 80% | 22.8% |
Staying on the field has been the bugaboo for Jenkins throughout his career, and in 2025, he’s been limited to just 55 games across all levels. Even so, Jenkins has shown improved game power, and under the hood, he remains a very similar player to previous years.
While Jenkins’ 102.4 mph exit velocity is average for his age group and uninspiring for a player with Jenkins power grades, his hit tool is impeccable. He boasts plus-plus contact skills with excellent approach, and he swings at pitches over the heart of the plate at a high rate while not expanding the zone. He shows the ability to hit the ball at optimal angles and lift the ball to his pull side.
Health issues have likely impacted Jenkins’ ability to put on muscle, but his impact data is certainly something to monitor. That said, his hit tool and angles are both excellent and should continue to help him see strong results.
Max Clark, OF, Tigers
| Swing% | Z-Whiff% | Miss% | Chase% | 90%EV | HardHit% | Heart% | PullAir% |
| 38.10% | 12.70% | 18.70% | 19.20% | 105 | 43.80% | 67.50% | 15% |
The Tigers have one of the best tandems of prospects in the minor leagues in McGonigle and Clark—and the data backs that up.
While not McGonigle’s equal at the plate, Clark also boasts traits of a plus-plus hit tool. He rarely swings and misses while expanding the zone, either. Clark’s one knock is he can get overly passive at times, but that’s not the worst trait for a leadoff profile.
Clark shows well above-average raw power with a 105 mph 90th percentile exit velocity and a plus hard-hit rate. His angles and ability to get to his pullside power are still improving, which is encouraging, as Clark is one player in particular for whom unlocking pullside home run power could pay dividends. He has the prerequisite hard contact, so it’s simply a matter of hitting the ball out to the shorter parts of the park.
Overall, Clark boasts a host of traits that will serve him well whenever he debuts with the Tigers in 2026.
Edward Florentino, OF, Pirates
| Swing% | Z-Whiff% | Miss% | Chase% | 90%EV | HardHit% | Heart% | PullAir% |
| 39.00% | 11.40% | 17.50% | 19.50% | 103.8 | 38.00% | 67.3% | 33.9% |
In 2025, Florentino has been a revelation for the Pirates. With a strong performance across the Florida Complex League and Low-A Bradenton, the 18-year-old has catapulted himself onto the Top 100 list and into the top five of the Pirates’ system.
Florentino’s data across the board is phenomenal, and in some ways might be even better than his outstanding performance. He shows excellent bat-to-ball skills, a patient approach and legitimate plus power for his age and level.
The most optimized part of Florentino’s game is his bat path, as he shows a knack for finding the barrel and elevating the ball to his pull side. While he can be somewhat passive in the zone, that’s likely to improve in the coming years, potentially leading to even louder power results.
Caleb Bonemer, SS, White Sox
| Swing% | Z-Whiff% | Miss% | Chase% | 90%EV | HardHit% | Heart% | PullAir% |
| 38.50% | 14.60% | 22.70% | 19.20% | 104.2 | 38.50% | 69.8% | 29.3% |
While some may have jumped ship on Bonemer after a bad month of June, things turned around for him in July, and the 2024 second-round draft pick has ended up as one of the best hitters in Low-A this season.
Bonemer has been outstanding throughout 2025, showing plus bat-to-ball skills and strong on-base ability. His one nit to pick is he can get overly passive at times, taking too many pitches over the heart of the plate. Swinging a little more wouldn’t be the worst idea for Bonemer, who not only shows the aforementioned contact skills but also a high level of contact quality.
Bonemer also shows potential for plus power, as evidenced by exit velocities two deviations above the standard for his age/level and an elite PullAir%. Overall, he has handled one of the worst hitting environments in the Carolina League this year and passed with flying colors.
Carter Jensen, C, Royals
| Swing% | Z-Whiff% | Miss% | Chase% | 90%EV | HardHit% | Heart% | PullAir% |
| 42.30% | 17.90% | 27.50% | 20.20% | 106.9 | 55.10% | 70.6% | 18.5% |
Now on the Top 100 list, Jensen has been a hitter with strong analytical markers going back a few seasons. In 2025, everything is up a little across the board, and Jensen’s stock has risen accordingly.
While there is some swing-and-miss in Jensen’s profile, he’s also facing the highest level of competition in the minors and producing. He shows average bat-to-ball skills, but they come with above-average approach and plus power.
Jensen thrives by consistently producing hard contact. He’s not fully optimized for pullside power, but he has the type of power that allows him to hit the ball out to any part of the park. His underlying power is plus with at least average plate skills supporting it.
Jensen could be in the Royals’ plans for a September callup, as he’s more than earned it.
Theo Gillen, OF, Rays
| Swing% | Z-Whiff% | Miss% | Chase% | 90%EV | HardHit% | Heart% | PullAir% |
| 35.20% | 17.60% | 26.10% | 14.80% | 103.2 | 42.70% | 66.7% | 19.8% |
A 2024 first-round pick from the Texas prep circuit, Gillen has traditionally been known for his tools and projection. In 2025, however, it’s been his elite on-base skills that have drawn headlines.
Gillen boasts a 19.8% walk rate, and it’s backed by a 14.8% chase rate—an elite number. He is definitely still passive—as shown by his lower heart-swing rate and swing rate—but there’s a fairly sizable difference between his swing and chase rates. That gap reflects some aggression in the zone, keeping his heart-swing rate within effective levels.
On contact, Gillen shows potential for plus power as well as some ability to get to his pullside power now. His hard-hit rate is plus for his age group, and his angles are strong enough to produce a 57.4% air-hit rate.
Gillen has true five-tool potential and could be a player who breaks out in a big way in 2026.
Rainiel Rodriguez, C, Cardinals
| Swing% | Z-Whiff% | Miss% | Chase% | 90%EV | HardHit% | Heart% | PullAir% |
| 43.20% | 20.60% | 24.10% | 24.20% | 105.6 | 42.30% | 76.7% | 28.1% |
One of the stars of the 2024 Dominican Summer League, Rodriguez has made a splash in his stateside debut by performing admirably between the Florida Complex League and the Florida State League.
Rodriguez does have some swing-and-miss, but it’s primarily in-zone. He shows the ability to hit a wide variety of pitches and locations—often out of the zone—and he makes strong swing decisions while rarely missing pitches over the plate.
Rodriguez’s selling point is his elite quality of contact. He shows plus-plus power for his age with a combination of both elite exit velocities and excellent launch angles. While he can hit it out to any part of the park, he especially shows real pullside power ability, suggesting higher future home run totals than other players his age.
While Rodriguez’s defense is still in question, his bat looks to be elite.
