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.

M4P frame-by-frame delivery analysis: the set, peak leg lift, hand break, mid-stride, release, and contact, each annotated — The analysis every athlete gets: swings and deliveries broken down frame by frame, with annotated stills — not a verbal "looked pretty good."

The relationship, plainly: M4P is an independent training business founded and run by Connor Jenkins, who is also the High School Director at Southside Prospects. That overlap is the point — the person building the club's training system coaches inside it. Club dues go to Southside Prospects; M4P memberships, camps, and clinics are paid to M4P, with the discounted club rate applied for Southside athletes.

Getting Started

How a Southside athlete starts

The entry point is the M4P assessment — a movement screen, complete baseline, and film, with a full written evaluation — so training starts from measurements, not guesses. Book it directly with M4P.
