Foul balls data could be the secret to the gaining an edge when scouting hitters.
A hitter's foul spray tells you his timing and how to attack him.
Here’s what the data says 🧵
The MLB strike zone this year is smaller than it was last year, and last year's zone was significantly smaller than it was in 2024. This year's adjustment at the bottom of the zone is I believe largely tied to the shift from front of plate measurements to mid-plate.
Really good answer from Michael Busch about how Trajekt has helped him develop against lefty arms.
His wRC+ jumped from 81 to 111 vs lefties this season.
In-game applications of Trajekt are cool, but the training environment applications have always intrigued me more.
【Types of One-Seam Sinker Grips】
I like the one-seam sinker for its big drop with high spin efficiency.
There are several grips: like a curveball, angled two-seam, or two fingers on one seam.
Curious what each grip does.
Why you should throw two sliders 🧹
Each version plays a different role. The gyro gives you late, sharp depth, while the sweeper gives you big horizontal.
