In Part 1 of this article, we covered in great depth the optimal metrics for an MLB fastball based on “slugging averages against” during the 2021 season. In Part 2, we are going to cover the optimal axes for:
-
- Curveballs
- Changeups
- Sliders
- Cutters
The green curves on the charts below are based normal distributions derived using statistical analysis. If you would like further information on these charts please refer to Part 1 using the link above.
1. Curveballs
The most optimal tilt axis that generated the lowest avg SLG in the MLB during the 2021 season was around 4:15 (n=187).
2. Changeups
The most optimal tilt axes that generated the lowest avg SLG in the MLB during the 2021 season was around 9:40 and 11:00 (n=266).
3. Sliders
The most optimal tilt axes that generated the lowest avg SLG in the MLB during the 2021 season was around 12:30 and 4:00 (n=365).
4. Cutters
The most optimal tilt axes that generated the lowest avg SLG in the MLB during the 2021 season was around 11:00 and 12:30 (n=122).
