An actual return-to-throw experience.
“After finishing early rehab from Tommy John surgery, I knew I needed a place that went beyond the basics. Athletic Potential built a fully customized return-to-throw plan and continued rehab/performance program around my needs. The process was collaborative from start to finish, and I surpassed my goal, with my fastball back to 96 mph with my offspeed and breaking balls looking sharp.”

The six-phase progression
Your starting point depends on the injury and what your arm can handle now. Open a stage for the work involved and the criteria we review.
Phase 1: Tissue HealingProtect healing tissue. Settle symptoms. Maintain everything else.
Tissue- and procedure-dependent
The early plan is constrained most by tissue-healing biology. A UCL repair, labral repair, rotator cuff procedure, and non-surgical injury do not share the same milestones. Protection and loading reflect the tissue, procedure, symptoms, and surgeon guidance.
Protection does not mean inactivity. We train what is safe: legs, trunk, conditioning, mobility, and the uninvolved arm. The goal is to maintain as much athletic capacity as the injury allows.
What we review before advancing
- Daily symptoms are controlled
- Motion meets current protocol targets
- Swelling and irritability are stable
- Healing permits progressive loading
Phase 2: Range of MotionProgress shoulder and elbow motion within the tissue-healing constraints. Begin appropriate loading.
Protocol- and response-dependent
The tissue can begin handling more stress, but the motion and loading allowed here depend on the injury, procedure, healing time, and surgeon guidance. We work toward the appropriate shoulder and elbow milestones without forcing internal rotation, end-range motion, or resistance before the tissue is ready.
The rest of the athlete keeps training too. Hip and trunk mobility, lower-body strength, and conditioning help preserve the physical base that throwing will eventually require.
What we review before advancing
- Motion is progressing as expected
- Loading does not create a lasting flare
- Early arm strength work is tolerated
- Ready for more dynamic loading
Phase 3: StrengtheningBuild tissue tolerance for explosive force. Prepare the arm for the demands of throwing.
Progressed by capacity, not the calendar
Before throwing begins, the arm needs exposure to faster force. Strength work creates capacity; plyometric work teaches that capacity to show up at the speed and rhythm of a throw.
Plyometric loading bridges the gap. Depending on the athlete, this may include wrist-weight drills, reverse throws, pivot pickoffs, or low-intent ball work. Upper-body, trunk, and posterior-chain strength continue to progress alongside the arm.
What we review before advancing
- Arm strength is appropriate for this stage
- Plyometric work is well tolerated
- Testing supports beginning a throwing plan
- The body can support throwing demands
Phase 4: Return to ThrowReintroduce throwing while progressing volume, distance, intent, and velocity.
Progressed by workload and recovery
The throwing workload is rebuilt through catch play and, when useful, constraint drills. Throw count, distance, velocity, intent, symptoms, and recovery each describe a different part of the dose. Radar can anchor intensity without replacing clinical judgment.
Workload data and planned velocity zones help organize the progression. Strength, forearm capacity, movement quality, symptoms, and recovery help us decide whether to hold, advance, or adjust the next session.
What we review before advancing
- The current throwing dose is well tolerated
- Recovery is predictable between sessions
- Arm capacity remains stable as throwing increases
- Ready for the next workload change
Phase 5: Mound WorkTransition to the mound. Reintroduce slope, pitch mix, and competitive intensity.
Individualized by role and response
Moving to the mound changes the context: slope, approach, timing, intent, and pitch-specific demand. Flat-ground tolerance does not by itself establish bullpen readiness.
We usually adjust one major variable at a time, such as volume, intent, pitch mix, or frequency. At our Kent facility, radar, PULSE workload tracking, and video can help us understand how the athlete responds as mound demands rise.
What we review before advancing
- Bullpen workload is well tolerated
- Pitch mix and intent progress appropriately
- Strength remains stable between outings
- Recovery matches the planned schedule
- Volume fits the athlete's role
Phase 6: Performance HandoffProve full-effort bullpen tolerance and prepare the next coach to take over.
Based on readiness and next setting
Full-effort bullpens are the final throwing checkpoint we manage. The athlete demonstrates repeatable tolerance to the pitch count, intensity, pitch mix, recovery, and weekly workload needed for the next setting.
The next phase depends on the athlete. Some return to their team or private coach. Others move into Driveline for motion capture, live at-bats, pitch design, or pitching development. We provide the workload history, velocity data, and strength benchmarks that tell the next coach where to begin.
What we review before advancing
- Full-effort bullpens are repeatable
- Velocity and command meet handoff goals
- Recovery is predictable between outings
- Strength remains stable under mound workload
- The next coach has the plan and data
From catch play to repeatable bullpens.
Change the throwing dose deliberately.
Distance, intent, volume, pitch mix and frequency each change the demand. We build mound exposure in stages and review how the arm recovers between outings.
Use velocity as context.
Radar gives us a shared reference for intensity. Throw counts, strength, symptoms and recovery help decide whether to hold, advance or change the plan.
Make the handoff useful.
We manage rehab through full-effort bullpen tolerance. The next coach receives workload history, velocity information and strength benchmarks for the next setting.
Pitching development and two-way players
Clear Roles
REHAB STAYS WITH YOU THROUGH THE BULLPEN.
Athletic Potential manages the injured arm, strength, throwing workload, mound progression, and full-effort bullpens. Once those demands are repeatable, we hand off a clear workload history to the team, private coach, or next training setting.
PITCHERS
We build the arm through full-effort bullpen work. Athletes who want motion capture, live at-bats, pitch design, velocity development, or command training can then move into Driveline's pitching program.
TWO-WAY PLAYERS
Hitting often returns before pitching. A two-way player can begin hitting and strength training with Driveline while Athletic Potential continues to manage the throwing progression. Both staffs coordinate workload as the arm catches up.
Progression decisions
TESTING SHOULD ANSWER THE NEXT QUESTION.
Each measure should help us hold, advance, or change the plan. We choose the tools that fit the athlete, the current phase, and the decision in front of us.
The tools behind the decisions
Stalker & Pocket Radar
Velocity zones across catch play, constraint drills, and mound work.
Driveline PULSE
Arm speed and throw counts. Daily and weekly load.
ArmCare
Isometric strength testing, IR, ER, scap. Tracks symmetry.
FlexPro Grip
Grip and forearm capacity alongside symptoms and throwing load.
Workload tracking
A real return-to-throw, charted day by day.
Daily throw counts, acute-to-chronic context, and the chronic load curve over time help us review how the workload is changing.
Velocity progression
Every throw, by intensity zone.
Velocity zones show how intent is changing. Peak velocity, workload, symptoms, and recovery are interpreted together.

QUESTIONS ATHLETES AND PARENTS ASK
If you're deciding whether this fits, start here.
The tissue, procedure, healing time, symptoms, motion, strength, and surgeon guidance set the starting point. A date can describe when throwing may be considered, but the athlete still needs enough capacity to tolerate the first workload.
There is no universal order for every arm. Distance, intent, throw count, frequency, and drill type all change stress. We adjust the variables deliberately and watch the response during the session, later that day, and the next morning.
Flat-ground throwing needs to be repeatable before the mound. We also review current velocity, workload tolerance, arm strength, recovery between sessions, the planned bullpen dose, and any procedure-specific restrictions.
Pitch mix returns after the athlete has built a stable throwing base and can tolerate the current fastball workload. The exact order depends on the injury, age, role, grip, pitch characteristics, and response to previous sessions.
No. Clearance usually means the athlete can begin a controlled throwing progression. Pitching requires higher intent, mound exposure, pitch mix, repeatable recovery, and enough weekly capacity for the role waiting in competition.
Ready to start your return?
