Thanks Dave,
Bummer, was looking for a bigger slice of Hitf/x
You can only do so much with 1 month of data

The pitchf/x data continues to be released daily.

The hitf/x data for the rest of the year they are collecting with the pitchf/x data but not releasing. It is my understanding that they are looking at different ways to monetize that data before releasing it. For example, maybe sell the data to the teams and let them have sole use of it for a given period of time before it goes public. I am not 100% on that, but that was my understanding of a possible model for its release.

The general baseballf/x stuff is off in the future still in the research phases. Marv said that he couldn’t put a timeline on its release.

Are we going to have to view that data in graph form, or will a red line be drawn to categorize popups, fly balls, deep line drives, etc.?

Wouldn’t you need the spin of the ball off the bat to have truly complete data? I’d think it would be fairly similar for each ball of similar trajectory and speed except that the spin of the ball coming into the bat probably affects it coming off, so fastballs and curveballs etc. may differ in some regards when they are batted at equal angles.

It was great to meet Eric, Harry, Peter, Colin, Max, Matt, Alan, Dan, Greg and lots of other folks I had previously only known through their online writing!

Very true, and based on what I heard it sounds like that day is coming quite soon. Sportvision has the speed of the ball off the bat and vertical angle with the HITf/x data. Those effectively replace GB, LD, and FB. It is not clear at this point when they will start releasing that data, but it shows that the days of GB etc are very numbered.

There is going to be a day when we look back and laugh that we once used GB, LD, and FB% to evaluate batted balls.

Thanks for the recap.
