How swing decisions are evaluated in the Diamond Stats App.
I chose to use a simple model, that while it isn't perfect, gives a pretty good idea of whether your players are making good swing decisions.
The swing decisions grade takes the players Heart Swing % and divides it by their Chase Swing %. Basically it rewards swinging at pitches you can do damage on, and taking pitches that are tough to hit.
The app also includes Pitches/PA, Swing %, and 1st Pitch Swing%. These aren't factored into the grade, but can be used by coaches to evaluate a players patience at the plate, and ability to work counts.
FYI, the app is FREE to use!

How do we grade and evaluate bat to ball skills in the Diamond Stats App?
The actual Bat to Ball grade is calculated by assigning run values to balls hit in play, foul balls, and whiffs. That score is then converted into a grade on an 80-20 scale. This grade has a very high correlation with baseball savants Squared Up/Swing stat.
We also break down each player's bat to ball skills in different parts of the strike zone (Heart, Edge, Chase) to get a more detailed look at the hitters strengths and weaknesses.
Finally, we have a contact quality profile for each player that allows you to see the type of contact the player is making, and how often.

First Core Four metric in the Diamond Stats hitting app is Power.
Power is going to be broken down into 4 stats
- Bat Speed
- Exit Velocity
- ISO
- Extra Base Hit %
Bat speed and exit velocity going to set the ceiling for your raw power potential. ISO and XBH% are going to show how well you are transferring your power potential into actual in game power.

Baseball Coaches! I made a FREE web app
Game Changer wasn't giving me all the hitting stats that I wanted so I built an app that would.
Diamond Stats tracks and grades your hitters in these 4 skills/categories (Core Four)
- Power
- Bat To Ball
- Swing Decisions
- Ball Flight
The main goal behind this was to track my players skills in these 4 areas, so we could identify a hitters strengths and weaknesses and work on them accordingly
