The one-line read

Travis is operating at a genuinely elite level for pro baseball — a +24% power build since November, carried through an in-season block, elite grip, and a well-balanced throwing shoulder. The trainable margins: the left leg in single-leg power, and holding the right-shoulder gains from this summer's arm-care block.

Five priorities

Left-leg single-leg power
Single-leg jump: right 25.3 cm vs left 21.7 cm — a 14% gap (symmetry 86%, target >90%), and the CMJ leans +8–10% right most sessions. Close it with a left-biased unilateral block.

Hold the right-shoulder rebuild
April flagged the right shoulder well behind the left (abduction −31%, flexion −22%). July 10 re-test: abduction 154 → 245 N, flexion 171 → 230 N. Now keep those gains through the throwing load.

Shoulder mobility surveillance
Right shoulder ER 119° / IR 47° (166° arc) — a classic thrower's profile. IR of 47° warrants a left-side comparison next session to rule GIRD in or out.

Eccentric / landing symmetry watch
The final May session spiked to 17% right-dominant eccentric asymmetry — single-trial, but eccentric load is where soft-tissue trouble starts. Keep it on the weekly monitor.

Finish the profile
No drop-jump, sprint, or rotational baselines on file, and no left-shoulder comparison. Adding these completes the elite profile.

The engine — eight force-plate sessions, one direction

Travis has jumped on dual force plates (1,000 samples/second) eight times across nine months. The trend is what elite monitoring is supposed to look like: a big off-season build, then power that kept climbing through an in-season weekly block instead of eroding.

The headline win. Relative peak power rose from 58.2 → 72.2 W/kg (+24%) and jump height from 47.1 → ~59 cm between November and May — at essentially unchanged body mass (98.5 → 99.2 kg). That's added output, not added weight. And the April–May in-season block didn't just hold: every power metric trended up while he was competing.

Session-by-session (means across maximal reps)

Session	Jump Height (Imp-Mom)	Peak Power / BM	RSI-mod	Force Asym (con.)
Nov 13, 2025	47.1 cm	58.2 W/kg	0.66	+10.5% R
Jan 15, 2026	55.6 cm	68.1 W/kg	0.79	−8.9% L
Apr 13	56.6 cm	68.3 W/kg	0.77	+5.1% R
Apr 15	58.1 cm	69.5 W/kg	0.79	+8.0% R
Apr 22	57.5 cm	67.4 W/kg	0.74	+8.6% R

May 4	59.6 cm	70.4 W/kg	0.78	+8.2% R
May 11	59.0 cm	72.2 W/kg	0.75	+4.3% R

Imp-Mom = impulse-momentum jump height, the gold-standard force-plate calculation. RSI-modified = jump height ÷ time to take-off — how fast the force is produced, not just how much.

Symmetry — where the work is shared unevenly

Single-leg jump (Nov): right 25.3 cm · left 21.7 cm−14% left (symmetry 86%)

The clearest deficit on file. Per-leg testing strips away the bilateral jump's ability to compensate — and the left leg produces ~14% less. Target: >90% symmetry. This baseline is from November; re-testing it is the first item in the blueprint.

CMJ concentric force share — in-season pattern+8–10% right, most sessions

Consistent, moderate right-dominance in the two-leg jump — the same story as the single-leg gap, seen from the other side. Under 10% is acceptable; the trend matters more than any single reading. Interesting wrinkle: the January session flipped left-dominant (−8.9%), so the pattern is loading-dependent, not fixed.

Eccentric mean-force asymmetry — May 11+17.2% R (single trial)

One trial, so read with caution — but the eccentric (absorbing) side is where overuse issues start. Worth a clean multi-rep re-check at the next session.

The pattern: everything lower-body points the same direction — the left leg contributes less, on take-off and in single-leg work. At Travis's level this is a performance margin more than an injury alarm, but rotational athletes drive force up from the back leg — evening the platform is directly convertible to output.

The arm — grip, cuff & shoulder battery

Seventeen DynaMo dynamometer tests across April–July cover the pieces a professional throwing/hitting athlete lives on: grip, rotator-cuff balance, shoulder strength in every plane, and scapular control.

Grip is a weapon. Best readings: right 743 N (75.8 kg) · left 700 N (71.4 kg) — elite territory for professional baseball (typical pro range ~50–65 kg), with a healthy 2–10% right-hand edge across five test dates. Grip is one of the better global proxies for arm resilience and bat control, and both hands qualify.

Rotator cuff — internal vs external rotation (seated 90/90, Apr 13)

Side	Internal Rotation	External Rotation	ER : IR ratio	Read
Right	224.8 N	194.6 N	0.87	Excellent balance
Left	293.5 N	222.1 N	0.76	At target

The decelerators (external rotators) of a throwing shoulder should produce at least ~66–75% of the accelerators' force — below that, the brake can't match the motor. Both of Travis's shoulders clear the bar; the right sits at a genuinely strong 0.87.

April screen → July re-test: the right shoulder responded

Test (right side)	Apr 13	Jul 10	Change	Read
Shoulder abduction	154.1 N	245.4 N	+59%	Rebuilt
Shoulder flexion	171.4 N	230.3 N	+34%	Rebuilt

Honest caveat: April tests were seated, July standing (long-lever both) — position inflates the comparison somewhat. But gains of this size don't come from posture alone: in April the right shoulder tested 31% behind the left in abduction and 22% behind in flexion; in July it produced more force than the left did in April. The arm-care block worked.

Shoulder range of motion — right side (Jul 10, supine 90/90)

External rotation119°

The "lay-back" a thrower needs — ample.

Internal rotation47°

Total arc 166° — a healthy thrower's arc. But IR of 47° is the number to watch: if it sits ~15–20°+ below the left side, that's GIRD, the classic precursor to shoulder/elbow trouble in throwers. The left side hasn't been measured yet — capture it next session.

Scapular control

Test	Left	Right	Asym	Read
Scap retraction (best set, Apr 13)	182.7 N	154.6 N	−15.4%	Right lags — retest
Shoulder extension (standing)	214.6 N	273.5 N	+21.5%	Right-dominant

A second retraction set the same day read nearly symmetric at lower force (118/125 N), so treat the −15% as provisional. The scap is the platform the cuff fires from — worth a clean re-measure alongside the July strength gains.

Body Focus Map — where to train, and why

Every finding maps to a place on the body and a mechanism — what we found, why it matters physiologically, and what we train. Red = primary focus · gold = secondary / maintain.

How to read it: shaded zones are where the plates and the dynamometer agree the work should go. For a rotational athlete the two red zones bracket the kinetic chain — the back-leg drive at the bottom, the decelerating shoulder at the top.

1 · Left leg — single-leg power Primary

Found: single-leg jump 14% lower on the left (86% symmetry); bilateral CMJ consistently +8–10% right-dominant. Why: inter-limb gaps above ~10% blunt force transfer and concentrate load on the dominant limb; in rotational sport the legs alternate roles between drive and block, so a weak side leaks power in both directions. Train: left-biased unilateral strength (split squat, step-up, SL RDL), single-leg landing control, re-test SLJ at 4–6 weeks.

2 · Right shoulder — hold the rebuild Primary

Found: April: abduction −31% / flexion −22% vs left. July: abduction +59%, flexion +34% — rebuilt. Why: shoulder-strength deficits in professional throwers measurably raise injury risk; strength that is built but not maintained through throwing volume regresses within weeks. Train: keep 2×/week long-lever abduction/flexion + ER maintenance loads in-season; re-measure monthly, don't wait for symptoms.

3 · Posterior capsule / IR mobility Secondary

Found: right shoulder ER 119° / IR 47° (arc 166°). Why: throwers trade IR for ER — normal — but when total arc shrinks or the IR loss exceeds ~15–20° vs the other side (GIRD), shoulder and elbow injury risk climbs. The left side is unmeasured, so the comparison is open. Train: sleeper stretch / cross-body posterior-capsule work post-throwing; measure the left side next session.

4 · Scapular platform Secondary

Found: first retraction set −15% right; second set symmetric at lower force — noisy signal. Extension strongly right-dominant (+21%). Why: the scapula is the anchor the cuff fires from; retraction strength underwrites deceleration at release. Train: mid-trap/rhomboid rows, retraction holds; get one clean re-measure to settle the signal.

5 · Grip & forearms Maintain

Found: 75.8 kg right / 71.4 kg left — elite, stable across five dates, healthy 2–10% dominant-side edge. Why: grip reflects total-arm chain integrity and correlates with bat control and forearm-flexor protection of the elbow. Train: nothing corrective — keep heavy carries/holds in the program and keep monitoring; a sudden grip drop is an early overload flag.

Where he ranks. Five of six benchmarks sit in the elite band — engine, rate of force, grip, and cuff balance are all pro-plus. The single marker outside the band, single-leg symmetry, is also the most directly trainable, and it's a November reading taken before the +24% power build. Re-test first: the gap may already have moved.

The Blueprint

Travis doesn't need rebuilding — he needs protecting and sharpening. The plan keeps what's working (weekly monitoring, the arm-care block), closes the one real gap, and finishes the profile.

Phase 1 — In-season: protect & close (weeks 1–4)

Now

Keep the Monday CMJ monitor — it demonstrably works; power climbed through the last in-season block. Watch eccentric asymmetry after the May 11 spike (17% R).
Left-leg block, low dose — 2×/week: rear-foot-elevated split squat, SL RDL, left-biased step-ups. In-season volumes; quality over load.
Arm-care maintenance — hold the July shoulder gains with 2×/week long-lever abduction/flexion + ER isometrics; posterior-capsule mobility post-throwing.
Re-test single-leg jump — the 86% symmetry number is from November, pre-build. Get the current read before programming further.

Phase 2 — Complete the profile (weeks 4–8)

Measure

Drop-jump baseline — RSI + contact time; the only jump quality missing. At his RSI-mod (0.78), reactive numbers should be strong — confirm it.
Left-shoulder ROM + strength — the comparison side for the ER 119°/IR 47° right shoulder; settles the GIRD question.
Clean scap-retraction re-measure — one careful set to resolve the −15% vs symmetric discrepancy.
Sprint + rotational med-ball baselines — the transfer metrics that connect plate power to game speed.

Phase 3 — Off-season: raise the ceiling (post-season, 8–12 weeks)

Build

Max-strength block — trap-bar/squat progression; at 2.6–2.9× bodyweight peak concentric force there's headroom to convert strength to even more power.
Unilateral emphasis continues — target >90% SLJ symmetry by camp; heavy split-squat and single-leg landing/deceleration work.
Reactive/elastic block — depth drops and stiffness work layered on the strength base, guided by the new drop-jump baseline.
Full re-test — the complete battery, so next season starts with a sharper map than this one did.

Recovery & durability

In-season, recovery is training. Sauna, cold plunge and NormaTec at the recovery lounge slot cleanly into post-throwing days; grip readings double as an early-warning light — a sudden drop flags arm overload before symptoms do.

Fuel

Body mass held at 98–99 kg while output climbed 24% — the composition trend is right. Keep protein anchored per meal and creatine on board; no changes needed, just consistency through the grind of the season.
