What stands out
- The biggest ahead-vs-behind tilt of the four pitches profiled here: 42.7% ahead, only 18.4% behind.
- A relatively rare, slow offering: 22,473 thrown (3.24% of all pitches), median 86.3 mph.
- It nearly vanishes on 3-0 (0.1% of splitters) and clusters in two-strike counts like 0-2 (10.52%).
Reading note
Descriptive only, over a single 2025 Statcast pull. The count shares are of this pitch's OWN usage (what share of splitters fall in each count), not the share of any count that is a splitter. The strike bucket merges called, swinging, and foul strikes (no per-pitch swing/take in this corpus), so it is not a whiff rate. 'Biggest tilt of these four' is scoped to the four pitch types written up in this pack. Not a prediction; descriptive only.
