Roto Match Game: Guess Your Batted Ball Type

Major League Baseball Advanced Media collects and distributes the hit and pitch tracking data. This data gives the general public some additional information previously unavailable like pitch spin and batted ball angle. The system has almost removed the need for stringers (people who collect batted ball and game data) except for plays wich get immediately described for the Gameday feed. Each batted ball get the designation of a bunt, ground ball, fly ball, line drive, or popup. Sometimes, it’s tough to designate each batted ball type. Today, I am going to look at the triple point for line drives, pop ups, and fly balls.

For reference, here are all the batted designations since 2015 plotted against launch angle and batted ball velocity (Thanks to Sean Dolinar for creating the graphic).

Note: Some weird angle classification went on at the zero mark.

The area I am concentrating on borders the point at 60-mph launch speed and 35-degree launch angle. It’s the point where line drives, pop-ups, and fly balls merge into a blur. It’s time to see if you can tell them apart.

Here are six batted balls with a launch angle between 33 and 37 degrees and a launch speed between 58 and 62 mph. At least one was labeled a fly ball, line drive, and pop up. Can you guess how the stringers labeled them? Also, how would you want them labeled? I don’t have any prizes to hand out if someone happens to guess them right. Sorry. In the next couple days, I will go over the correct answers. Good luck, you’re going to need it.

 

Batted Ball #1
Launch Speed: 58.1mph
Launch Angle: 34.2 degrees

 

Batted Ball #2
Launch Speed: 59.4 mph
Launch Angle: 34.0 degrees

 

Batted Ball #3
Launch Speed: 61.0 mph
Launch Angle: 36.4 degrees

 

Batted Ball #4

Launch Angle: 33.6 degrees

 

Batted Ball #5

#3 is the only one I feel even somewhat confident about, which means it’s probably wrong.

They all look like pop-ups to me, with the last one kinda sorta looking like a fly ball. I don’t see how any of these can be seen as a line-drive.

I suppose the two that dropped were more likely to be seen as line-drives, and the ones caught, pop-ups. And I wonder what effect balls hit to the pull/oppo side have on classification. Maybe oppo more liky to be seen as a pop-up?

Throwing out a guess on how stringers would interpret these, with the assumption there are two of each classification, I’ll go:

1 – Line drive
2 – Pop up
3 – Pop up
4 – Fly ball
5 – Fly ball
6 – Line drive

Fun game. I would not call any of them line drives, but since we know there has to be at least one:

1. Fly ball
2. Popup
3. Popup
4. Fly ball
5. Fly ball
6. Line drive

No. That confused me at first too. 3 of the line drives were right and #3 and #5 are flyball/popup in some order. Each time he had 3 of the liners right and one of the others.

1. Flyball (really a popup, but I can’t have 3 in a row)
2. Popup
3. Popup
4. Flyball
5. Flyball
6. Line drive

I don’t think 6 is much of a line drive. LD% is supposed to be indicative of something positive, and #6 is not.

They are all shanks, except #4.

Holy shit I nearly cried tears of joy at how apt a use you found for the concept of the triple point in baseball: kudos good sir.

Ok, so “ducksnort/Texas leaguer/flare/bloop” all just need their own batted ball bucket! Amazing how many of these fell in for hits!

The graph reminds me of starling murmuration, which I find extremely visually pleasing.
