I’ve been doing a lot of griping lately about the state of tennis data, so I figured now was a good time to start doing something about it.
I’ve just released point-by-point data for most Grand Slam singles matches back to 2011. Beyond the basic point sequence–which is valuable in and of itself–you’ll find serve speed, winner type, and for a few of the slams, rally length for each point.
More detailed notes on the data are available at that link. Enjoy, and if working with it turns up any interesting findings, please let me know.
