What stands out
- It leans opposite to the splitter -- thrown more when behind (32.7%) than ahead (20.3%), a pitch used to steal a strike.
- A first-pitch staple: 31.3% of all sinkers came on 0-0.
- The highest in-play rate of the four pitches profiled here -- 21.1% -- fitting a contact-inducing pitch; 107,136 thrown, median 94.0 mph.
Reading note
Descriptive only, over a single 2025 Statcast pull. The count shares are of this pitch's OWN usage (what share of sinkers fall in each count/leverage class), not the share of any count that is a sinker. The strike bucket merges called, swinging, and foul strikes, so it is not a whiff rate; in-play is the batted-ball share. 'Highest in-play of these four' is scoped to the four pitch types written up in this pack. Not a prediction; descriptive only.
