Baseball Savant recently released some new bat tracking analytics. You may be aware of the previous bat tracking measures like bat speed. As you might imagine, it turns out that batting mechanics are complicated events to measure. Basically multiple components of the swing are interconnected in determining whether a hitter makes good contact with t he ball.
The new measures are swing path, attack angle, ideal attack angle and attack direction. I relied on Mike Petriello’s article to try to understand these metrics. If you want more detailed information, I recommend that you look at his article.
