Leo’s August baseline and September retest, with coaching ratings of 34/60 and 38/60

PLAYER DEVELOPMENT · FEATURED CASE STUDY

Leo’s swing.
Practice. Review. Retest.

What changed between August and September? Watch Leo’s practice clips side by side, explore selected swing frames, and follow the coaching priorities behind his retest report.

34/60 → 38/60 · Six-category coaching review

The baseline was scored retrospectively. These are human-reviewed report ratings, not automatic software scores or proof that the drills caused the change.

THE HITTING DEVELOPMENT PROJECT

Record a baseline.
Coach the change. Retest.

Twelve young players took part in the project. Seven completed a documented first retest, connecting individual coaching priorities with a fresh video review.

* Earlier baselines for six players were retrospectively mapped to the current rubric in their retest reports; Aaron’s baseline already used it. Each category is scored out of 10, total out of 60. These are video-based coaching assessments, separate from CQS contact quality. The records describe this group’s observed changes; they do not establish a guaranteed training effect.

VINCENT HALL / FOUNDER

THE PERSON BEHIND THE PROJECT

A love for baseball.
A reason to give back.

Vincent began coaching younger players during his freshman year. As Founder & Head Coach, he built Future Stars around hitting and fielding instruction, clinics, mentoring, and individual feedback. The separate Hitting Analysis project grew into a way to connect coaching questions with engineering and data.

COACHING MEETS ENGINEERING

From Coaching to Coding

Coaching younger players led Vincent to a practical question: how can we tell whether a change in a swing really helped? At Future Stars, short hitting videos, coach observations, targeted drills, and follow-up sessions make feedback more concrete.

Alongside the coaching program, Vincent contributes to the design and testing of an experimental hitting-analysis project. Its public Python prototype uses OpenCV and MediaPipe to explore what two-dimensional video can—and cannot—tell us about movement.

PROJECT STATUS · OCTOBER 2026

Observe. Build. Test.

The latest documented app version, v0.3.8, is being prepared for limited parent/player testing. Android is the current platform; iOS development is underway. The GitHub repository contains the educational Python prototype, methods, and development notes; it is not a download of the local app.

Video-based scores are estimates. Camera angle, visible evidence, and contact-frame selection limit what can be judged. The project is not a validated biomechanics diagnostic tool.
