| Metric | All-State 2/28 | Future Games | Δ |
| FB sitting | 89.0–90.7 | 89.8–91.9 | +1.2 |
| FB max | 91.3 | 92.4 | +1.1 |
| FB ride (IVB) | 11.2" | 13.5" | +2.3" |

| Extension | 5.8' | 7.0' | +1.2' |
| Breaker (SL→CB) | 72.6–76.7 | 77.9 | +0.7 velo |
The extension jump is the story — 5.8' to a legit 7.0' off a 6'5" frame, so the 90–92
plays up beyond the gun reading. Ride climbed with it (+2.3"), and the breaker firmed from a mid-70s slider into a 78-mph
sweeper he landed for a strike every time TrackMan saw it.
