Testing plus notes
This is development guidance, not a guarantee of performance, recruitment, roster status, or medical fitness.
What should he work on first?
AthleteOS starts by translating the parent question into a first evaluation point.
What changed
The read moved the family away from chasing every baseball trait and toward finishing routine defensive actions under game pace.
Week-one direction
Controlled field-and-throw reps with a scored finish: clean gather, direction to target, and throw accuracy before tempo increases.
Next measurements
10-yard split, throw velocity, fielding clean-rep percentage
Copy this when a parent asks a similar question.
Use the case file as proof, then ask for the athlete's sport, age, position, and biggest concern.
Baseball parent example: 12U 3B/RHP: the first thing I would evaluate is whether the throw stays accurate once the exchange speeds up. This is the kind of first-priority read AthleteOS is built for: not a generic drill list, but a clearer development order. https://athleteos-site.vercel.app/case-files/baseball-12-corner-infield-rhp
