USTA moved this player up a level mid-season in 2019. A published rating does not change until the end of the year, so the level shown above can be behind what USTA has already decided.

How often, across every team and every match we hold — including ones that do not count toward a rating. Advanced stats has a court-position table too, and it answers a different question: how well you do there, over matches that count. A team’s own page shows how that one team uses you.

I really think a champion is defined not by their wins but by how they can recover when they fall.
