2024 High School Slammer Score Days Review
Athleticism, Velo, Spin, Exit Velo, etc. - all of the metrics.
Between May and June, we evaluated 300+ of our high school athletes across the 2025, 2026, and 2027 classes - 22 teams in all between the North and South facilities. You can read more about the standardized evaluation: here.
Also, as a reminder, give @SlammersAD and @SlammerScore a follow on Twitter. We tweeted the best of every high school player’s data along with video from @SlammersAD. We retweeted some of the stand-outs from @SlammerScore.
Without further ado, leaderboards. Give this a scroll, check out the best of what Slammers has to offer! It is worth noting that because of early summer travel schedules overlapping with the end of high school playoffs, some players were unable to be evaluated during the May-June window.
Makeup opportunities were provided and there will be more opportunities in the near future.
Athleticism
Slammers utilizes the Loden Sports Performance Lab App to collect a Rebound Jumps test for each athlete and as a place to input and provide context for 10-yard and 30-yard run splits. The combination of the Rebound Jumps test and the 30-yard sprint with a 10-yard split allows each of our athletes to attain a Power, Quickness, Speed, and Loden Score – a true measure of their raw athleticism that correlates to things that matter on a baseball field. The Loden Score is a comparative to the average 22-year-old competitive athlete (6 is average). (All scores are 0-12).
Additionally, and as discussed previously, we have developed the Engine Score - a near-perfect correlation to expected velocity performance that factors in a rotational med ball throw as well. Learn more about the Engine Score.
Engine Score
At Slammers, we measure progress across a number of key indicators in what we’re trying to improve in the physical profile of each athlete - knowing that the physical profile directly impacts what happens on the baseball field. The Engine Score factors in both the jump power metric from the Loden Sports Rebound Jumps test and how an athlete performs on their rotational med ball throw (from their dominant side). The Engine Score metric gives a strong signal for expected velocity performance on-field for baseball (and softball) players. It’s almost a perfect correlation.
Our leaderboard here consists of a bunch of D1-committed 2025’s, some exciting uncommitted younger guys, and some interested 2025’s… If you’re into long-levers and big power potential, check out Sam Harry and Mason Griffin.
Loden Score
The Loden Score is an indicator of raw athleticism in an athlete. What kind of engine does this athlete have under the hood? Consider the Loden Score to be the foundation that each athlete has to work off of – it’s not the end-all-be-all, but the Loden Score is a good indicator for potential in an athlete.
A pair of 2025’s from up North in Trevor Gottsegen and Owen Morgan lead the way as the best pure athletes among the 22 Slammers High School teams.
Loden Speed
Speed is pretty self-explanatory. The first of the Loden Score traits to appear in younger athletes, speed sets the bar for what the engine of the athlete can become. Loden Speed is an index for top-end running speed.
3 Uncommitted 2025’s pace the leaderboard on the Speed Score: Trevor Gottsegen (recently the fastest player at PG National), Owen Elser, and Dustin Bennett.
A 9 Speed Score is exceptional and something that is rare even amongst high-level collegiate and professional baseball players. A few MLB players with an equivalent Speed Score? Ronald Acuna, Jazz Chisholm, Jarren Duran, Julio Rodriguez, Bobby Witt Jr., and Brenton Doyle.
Rebound Jumps Power
The average jump power of 3 jumps from the players Rebound Jumps test using the Loden Sports Performance Lab App (Loden Power Points). Power is correlated to exit velocity and throwing velocity (and many other things across a number of sports).
Mason Griffin and Martin Duff top this list with 74 LPP on their jumps. 70 LPP is average for a highly competitive, rising-junior in college and the ten guys on this leaderboard are already there.
In case you need a refresher: What is Power + Why is it important?
Rebound Jumps Height
The average jump height of the 3 jumps from the players Rebound Jumps test using the Loden Sports Performance Lab App (inches).
If you can jump high and you maintain that as you mature and add weight, your power is going to go up. Wyatt Rudden and Ari Rothman sit at the top of this one with impressive 29+ in. average jumps.
Pitching
Slammers utilizes Rapsodo to capture bullpens on all pitchers. For evaluation sessions, each pitcher throws either: 5 fastballs, 5 changeups, and 5 breaking pitches (or, if they have multiple unique breaking pitches) 5 fastballs, 4 changeups, 4 sliders, and 4 curveballs. Every throw is captured using Rapsodo’s slow-motion video feature with data overlay. All raw data was run through Slammer’s pitch grader tool.
Pitch Score
The average score based on pitch-specific criteria of all pitches thrown for the evaluation session (0-10).
A pair of uncommitted righties on Givens 2025 come in at 1 and 2 on this list: Anthony Graziano and Ryan McDougal. A high pitch score is a sign that a pitcher has multiple pitches that the data likes.
Max Fastball Velocity
The max velocity attained by each pitcher during their evaluation session.
For the second year in a row, Vedant Sharma leads the way - upping his 91.1 mph from last year to 92 this year.
Slider Spin
The average spin rate on each pitcher’s slider during the evaluation session. Generally speaking, the more spin, the more break on the pitch.
A pair of 2027’s found their way to the top of the Slider spin leaderboard in Cole Bobbin (Bitzer 2027) and Isaac Lockwood (Asnicar 2027). We look forward to watching these two rip off nasty sliders for years to come.
Curveball Spin
Similar to the aforementioned slider spin, curveball spin is the average spin rate on each pitcher’s curveball during the evaluation session. Generally speaking, the more spin, the more break on the pitch.
2-way, uncommitted 2025, Talan Hutchings is the lone Slammer from May-June evaluations to eclipse 2600rpm spin on his curveball. A handful of younger guys showing 2400+rpm is impressive.
Hitting
Slammers utilizes Rapsodo to capture standardized batting practice sessions for all hitters. For evaluation sessions, each hitter takes 15-20 swings with a goal of registering 12-15 batted balls for analysis. A pitching machine is set up at 40 ft. throwing ~60 mph. Every hit is captured using Rapsodo’s slow-motion video feature with data overlay. All raw data was run through Slammer’s BP Quality tool.
Swing Score
The average score based on hit-specific criteria (exit velocity, launch angle, spin rate, spin direction) of all hit balls from the players evaluation session (0-10).
Jayden Witkamp, a long and strong-bodied 2027 first baseman, sits atop the Swing Score leaderboard.
Max Exit Velocity
The hardest hit ball from the players evaluation session.
Plenty of thump in the 2025 class led by a quadrant of talent, uncommitted 2025’s at the top: Ryne Dodson, Josh McWilliams, Trevor Gottsegen, and Tommy Feldhake.
