Some updates on Fangraphs. Check out the various tabs in there. Tons of good stuff.
And, if you have suggestions, post them here. David is pretty much incomparable in terms of turnaround time of taking suggestions and implementing them.
Why do you think there is a difference with the “swing%” fields between the pitch f/x & BIS “plate discipline” sections for hitters? O-swing & Z-swing discrepancies make sense- but shouldnt the total swing % be the same?
Unless there is an appeal on a called ball, there isn’t any indication from the umpire whether a strike is called or swinging. For half-swings on pitches in or near the strike zone, different observers could disagree on whether there was a swing. Because of plays like that, it’s probably next to impossible for two independent sources to completely agree on swing data.
There could also be data entry errors, especially since I don’t think there is an official record to check swing/no-swing results against and help catch errors. It’s probably a little of both, but I would guess the borderline swing/no-swing pitchers cover more of the discrepancy than data entry errors.
In the new Plate Discipline Pitch fX section, there is a new stat called Pace. Does anyone know what that is?
Wasn’t pace the number of seconds between pitches?
Can you give a link Dave?
Pace is the time between pitches:

We’ve had it for pitchers in the pitchf/x section for a while, but never for batters. I haven’t looked much at fast/slow batters, but there does seem to be some really slow batters. Carlos Pena seems to consistently be the slowest.
If you want to publicize this a bit, show the pace numbers in terms of splits, at the very least: “Is this a Yankee-Redsox game or not?”, split.
You’ll get a half-dozen articles written about it…

Incredible story
wow their site is just getting more and more incredible. One thing I would recommend is getting this and pitch f/x for movement, and things like that on the leaderboards. I also recommend including spin on the player pages and leaderboards as my studies on this showed a pitch was much more effective when it spins more. I hate having to go to texas leaguers for spin data.
