Moving against him
In his favor / neutral
1. Genuine bat-speed decline (strength, health, or age)
32%Causal path: Strength / conditioning → Bat speed → Contact quality → Expected outcomes
- • Avg exit velocity −1.8 mph vs last season
- • Max exit velocity −2.1 mph vs last season
- • Hard-hit rate −9.0% vs last season
- • Fast-swing rate −8.4% vs last season
Against / absent: Bat speed −0.7 mph vs last season
Cannot distinguish strength loss from sub-clinical injury with public data — flag for training staff, do not self-diagnose.
2. Plate-discipline erosion — expanding the zone
31%Causal path: Swing decisions → Contact rate → Actual outcomes
- • Chase rate +5.6% vs last season
- • Strikeout rate +7.3% vs last season
Against / absent: Walk rate −0.2% vs last season · Zone contact −5.0% vs last season
3. Approach change — selling out for pull-side power
27%Causal path: Swing decisions → Batted-ball profile → Actual outcomes
- • Pull rate +12.0% vs last season
- • Strikeout rate +7.3% vs last season
- • AVG −.089 vs last season
Against / absent: Avg launch angle +0.2° vs last season · Barrel rate +0.1% vs last season
Unexplained / unobserved causes: 10% — confidence is deliberately capped; public data cannot see every layer.
Actions follow the top hypothesis; if video review rejects it, fall to the next.
- • Biomechanics (Hawkeye), TrackMan, and Blast Motion are team-internal — the mechanics layer is inferred from its downstream fingerprint, never observed.
