Bettors and modellers
Surface ratings and head to head, ready for a model
Every ATP and WTA singles result since 2007 with our Elo by surface before and after each match, head to head and records by surface.
Tennis models start from results and surface, and the free sources either stop at the score or cannot be used commercially.
Rebuilding Elo by surface from scratch means cleaning a decade of draws first.
What to build
Pre-match ratings
Every match carries both players' overall and surface ratings before it was played, so a model's features are one call per player.
Head to head by surface
Two players' meetings with wins split by surface and in finals, and every score.
Form on a surface
A season's record on one surface, with tiebreaks, deciding sets and share of games won.
What it will not do
- No sportsbook lines: ESPN publishes none for tennis, so prices have to come from elsewhere.
- No serve statistics (aces, double faults, break points).
