Here is the general leaderboard and information.

I've screenshot the general data and highlighted some of the outliers. 

And here is Mike Petriello's explainer column of the various data that is currently public.

Baseball Savanta (Statcast) is now tracking the following data:

• Bat Speed (72 mph is average, Giancarlo's average is 81mph, 3mph more than second place)
• Fast-swing rate (How often a batter swings faster than 75 mph+)
• Squared-up rate (how often a batter squares up the ball, as determined by EV efficiency)
• Blasts (Squared-up + fast-swing)
• Swing Length (who has a long bat path vs short)
• Swords (when pitchers fool batters into half swing attempts that look like a sword)

There's some super interesting data here, and I'm sure this will enter the baseball lexicon like spin rate and exit velocity has over the years. In the chart below, you want to be in the top right, and Juan Soto is king. But you can succeed with a lower bat speed when you make lots of good contact, and vice versa you can succeed with hyper fast bat speed making good contact less often.

As with pitch velocity and spin rate, extremely fast bat speed isn't the end goal, but over the aggregate it is better than not. The graphic below aired on SNB last night ans howed the difference in stats based on bat speed alone. High bat speed = good.

What else stands out to you?
