Tennis ratings

What these numbers are

It's an Elo rating: every result moves both players, and beating a strong player moves you more than beating a weak one. A newcomer moves fast and a veteran barely, so one upset won't rewrite a career. A 200-point gap makes the higher-rated player about a 3-to-1 favourite over three sets.

Each player carries an overall number and one per surface, and a match is priced off a blend of the two. That's why a clay specialist can sit 15th overall and top-five on clay. A surface column shows a dash until a player has 10 tour matches on it, because a rating built on a handful of results is mostly the starting value.

Only the active field is listed: anyone with a completed tour match in the last 365 days. Elo doesn't forget, so a retired champion would otherwise sit near the top for ever. Week shows how far each rating moved over the last seven days. The table rebuilds every morning from every completed match back to 2018, and it's the same rating every ATP and WTA projection on the site starts from.
