Maybe somebody's mentioned this before and I missed it, but Trackman data (pitching and hitting) for the games at LP (at least, it's the only PG site where my son has played) is now live and, apparently, free.

Pretty cool, though there appear to be at least a few glitches, with the wrong pitcher's info being tracked for my son in some games. That could just be initial growing pains in getting all setup for public consumption though, since it doesn't look like the data goes back that far and/or only contains a subset of the games from last year. Maybe PG can chime in and let us know if that's correctable easily (in the two cases I saw for my son the transition to the new pitcher is easy to detect because of velocity or handedness, though it might be difficult to know who the correct reliever actually was).
