Enhanced Gameday? Enjoy it while you can? Or do you enjoy it?

While I've never been fond of the "Enhanced Gameday" from, it's clear that some people are crazy about it.

In the New York Times "Keeping Score" column, Dan Rosenheck describes how some researchers and scouts are poring over the data, presumably using computers that have a lot more RAM and processing power than mine.

Some work has also been done on identifying batters’ tendencies: Iván Rodríguez swings at nearly 60 percent of pitches thrown to him out of the strike zone, and Juan Pierre makes contact with 92 percent of the balls out of the zone he swings at, for example.


“Will chase curveballs low and away” will become “swung and missed at 73 percent of pitches thrown under 83 m.p.h. with a vertical break of at least 12 inches on two-strike counts on the outer third of the plate.”

“Slider lacks bite” could be replaced by “slider begins to break 30 feet from home plate.”


The possibilities for use of the data are virtually endless — assuming, of course, that it remains publicly available. Although no changes are expected while the system is in development, Schwartz would not guarantee that it would always be accessible for free to the public, saying that “upper management” would eventually decide whether to charge for the information. While there is little doubt that the 30 major league teams can have the data if they want it, the broader statistically minded fan base — and the army of independent researchers included in it — may be shut out.

Shut out? But what would happen to my pFX jokes? Those were comedy gold!

There's is no truth to the rumor that is attempting to tell people more quickly what actually happened in the game.

So, they're thinking of charging for Enhanced Gameday? Does that mean a return of classic Gameday, or that fans will just be out of luck? (Waits patiently as Bud Selig points pistol in the direction of his foot yet again...)

wait, so gameday pitch locations are accurate?

I don't think that this means they will be charging for Enhanced Gameday, but rather, they will be charging for Enhanced Gameday's data. These researchers don't use Enhanced Gameday per se for their research, but rather the the XML files that provides for free from their database. Thus I'm guessing this merely means those XML files will require payment, but Enhanced Gameday will remain free and provide everyone with tons of pFX fun (which I actually don't mind, as if you know what you're reading, it indicates the type of pitch rather clearly).

If anyone's curious, here is the database:

And here is a sample Enhanced Gameday XML readout for some pitcher (pitcher 121834 to be exact...):

But I'm not that smart. I just want to know what happened. Mainly because I use Gameday not as a tool to analyze a game, but rather a way to check in on a game's progress when I can't get to the radio or TV.
