This repo contains my master WTA player file, historical rankings, and an extensive database of match results.
The player file columns are: player_id, first_name, last_name, hand, birth_date, country_code.
The columns for the ranking files are: ranking_date, ranking, player_id, ranking_points, tours. 'Tours' is WTA jargon for certain types of tournaments played, and that column is not anywhere near complete.
Match result files (e.g. 'wta_matches_2014.csv') contain all tour-level singles matches for that season. To make them easier to use, I've included a fair bit of redundancy with the biographical and ranking files: each row contains several columns of biographical information, along with ranking and ranking points, for both players.
ITF, tour-level qualifying, and some ITF-level qualifying match results are stored in a separate yearly file (e.g. 'wta_matches_qual_itf_2014.csv').
Most of the columns in the results files are self-explanatory. For more details, see the matches_data_dictionary.txt file in the parallel tennis_atp repo.
These files are in the same format as my ATP player, rankings, and results databases (https://github.com/JeffSackmann/tennis_atp). There's a small amount of sample code available there (https://github.com/JeffSackmann/tennis_atp/tree/master/examples).
If you find a bug, please file an issue, and be as specific as possible.
Feel free to correct bugs or fill in missing data via pull requests, but be aware that I will not merge PRs. But if that's the most convenient way for you to submit improvements to the data, that's fine; I can work with that.
If you'd like to contribute to the project, I post "help wanted" issues, starting with a plea to fill in biographical data such as date of birth.
If you'd like to contribute to my ongoing project to build a research-quality dataset of pre-Open Era women's tennis results, please familiarize yourself with the ongoing work at the Blast From the Past section of tennisforum.com. Additional tournaments, results, notes, and corrections are welcome there. Note that I cannot speak for the moderators there--please follow their guidelines and standards for contributions.
Also, I encourage everyone to pitch in to the Match Charting Project by charting pro matches. It's not a direct contribution to this repo, but it is a great way to improve the existing state of tennis data.
