A working camp, not a showcase

Showcase events measure you, post a number, and move on. This is the opposite: three hours of actual work across hitting, pitching, and defense, where the measurements exist so the coaching lands — and every athlete goes home knowing exactly what to fix and how to fix it.

What We Work

The curriculum

01

Hitting

Move-pattern and swing breakdown, bat speed and exit velo baselines, tee and machine work with live feedback.

02

Pitching

Delivery on video frame by frame, velocity readings, arm-care and strike-throwing work off the mound.

03

Defense

Footwork, glove work, exchange and transfer speed, throwing accuracy under a clock.

Every Rep Measured

The measurement stack

  • HitTrax — Ball flight, exit velocity, and hitting data on every swing.
  • Blast Motion — Bat-sensor metrics: bat speed, attack angle, swing plane.
  • Pocket Radar — Pitch and throw velocity, captured rep by rep.
  • Biomechanical sensors — How the body moves, not just what the ball does.
  • Frame-by-frame video analysis — Swings and deliveries broken down frame by frame.

Before You Register

Camp FAQ

Is this a showcase?
No — and that's the point. Showcases measure you and mail a number. This is a working camp: your reps get measured and coached, and you leave knowing what to fix and how.
My athlete isn't a Southside Prospect. Can they still come?
Yes. The camp is open to any high school player, grades 9–12. M4P is the official training arm of Southside Prospects, and we run this camp together — but the coaching is for everyone in the building.
What if my athlete has never trained with data before?
Then this is the best possible starting point. The tools — HitTrax, Blast Motion, Pocket Radar, video — just measure what's already happening. The coaches turn those numbers into one or two things worth working on.
Do parents stay?
You're welcome to watch — it runs 10:00 AM to 1:00 PM with check-in at 9:45. Drop-off works too.
Can teammates register together?
Yes — send them the link. Each athlete registers separately on the registration page.
What if plans change after we register?
Registration and payment run through the club's LeagueApps page. If plans change after registering, email connor@southsideprospects.com and we'll get you to the right person.
