Start with a comfortable throw
Warm up under an adult's plan. Use an easy, balanced motion toward a reachable target before adding intensity. Stop and tell the adult about elbow or shoulder pain.

Warm up under an adult's plan. Use an easy, balanced motion toward a reachable target before adding intensity. Stop and tell the adult about elbow or shoulder pain.
For a basic four-seam fastball, place fingers across the seams with a relaxed hand and comfortable thumb support. A two-seam grip follows the paired seams. Hand size can change the exact placement.
A coach can show a comfortable changeup grip that looks like a fastball delivery but moves at a different speed. Control and a pain-free motion matter more than forcing a particular grip.
Begin balanced, move toward the target, rotate through the throw and finish under control. Rehearse without a ball, then throw at a comfortable effort. A legal set or windup depends on the division and game situation.
The adult records actual pitches and catching use; this checklist is only a learning record. Report fatigue or pain and follow the adult's rest plan.
From 50 feet, rehearse a balanced fastball delivery before trying a comfortable changeup grip. End the set when control or comfort changes.
Section 01
Before throwing, tell the adult about fatigue or elbow/shoulder pain. Pain is a reason to stop pitching and seek medical evaluation, not a cue to push through.
I checked readiness with my coach before this supervised practice.
Use a calm check-in that makes reporting symptoms easy.
Do not turn a checked box into medical clearance.
A player can take part in non-throwing learning while an adult arranges appropriate care.

Section 02
With a ball in hand and no throw, compare a comfortable fastball grip and a coach-taught changeup grip. Basic throwing comes first; a grip is not a promise of velocity.
I compared the grips under supervision without forcing a painful hand position.
Start with the player's hand size and comfortable control.
Do not force a professional grip on a smaller hand.
This lesson does not prescribe a breaking-ball or weighted-ball program.
Related rule or safety source: Safety
Section 03
During a dry rehearsal, establish balance before moving toward the target. Keep the practice cue simple enough to repeat.
I rehearsed a balanced starting position with my coach.
Observe the whole movement before adding another cue.
A pose that looks right is not proof of a comfortable throw.
Use individual coaching for a persistent movement problem.

Section 04
With runners aboard, rehearse a complete legal stop in the set position before delivery.
I demonstrated a controlled set-position stop under supervision.
Separate a legal delivery from a legal base throw; begin without live runners.
Do not import the Little League Majors no-stop exemption.
Bronco lead rules do not license illegal pitching mechanics. PONY does not use MLB's pitch clock or disengagement limit.
Related rule or safety source: Balk Leaving a base
Section 05
In a coach-approved throwing progression, aim for a reachable target and prioritize a comfortable repeatable motion over a radar-gun number.
I used the agreed target and stopped when control or comfort changed.
Keep the emphasis on a sound basic throw, then fastball and changeup development.
Do not add maximum-effort throws to chase a screen score.
The checklist records a learning step, not prescribed repetitions or exercise dosage.
Related rule or safety source: Safety
Section 06
The adult reviews league age, all same-day pitching, required rest and readiness. PONY can permit pitching in more than one game on a day within its combined maximum.
I asked the adult to verify the complete day's workload and eligibility.
Use PONY 10(D)-(I), including its final-batter provisions and ban on same-game pitcher return.
A second game is not a new pitch allowance, and numerical eligibility is not medical clearance.
Use the actual game record; these learning checkboxes do not store a pitch log.
Related rule or safety source: Pitching limits Rest Pitching limits Safety
Section 07
After the practice, tell the coach how the arm feels and discuss the next throwing day using the adult's workload record.
I completed the post-practice check-in and know to report pain or fatigue.
Coordinate all throwing commitments rather than treating each team in isolation.
Completing all boxes is not permission for another throwing session.
Keep regular off-season rest and varied non-throwing activity in the longer plan.

Connect learning and practice
Discuss workload, rest, eligibility and stop conditions with a responsible adult. A checklist or quiz result never clears a player to throw. Choose any physical rehearsal deliberately from the complete planner instructions.
Read the complete setup, equipment and stop instructions before activity. A missed question never prescribes extra throwing.

Three fingers can support the basic fastball when two do not fit comfortably. This is a fastball hold, not a changeup.

Use the legal pitching setup for this division. With runners aboard, the set-position stop belongs to this delivery branch.
A separate choice before committing to a pitch. Rehearse the required step and throw with the coach; this is not the next step after delivery.
A separate step-off choice. Ask the coach to demonstrate the pivot-foot action and the rules that apply after leaving the rubber.
