Our model did not follow this player through that season: none of their matches that season carried an individual NTRP level (55 & Over and combo leagues are rated on combined levels), so it had nothing to start from. The match still counts toward the USTA rating.

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.

Not affiliated with or endorsed by the USTA. Ratings labelled as published are USTA year-end figures; anything we describe as an estimate is ours, not USTA’s. Match data is from USTA TennisLink.

You always want to win. That is why you play tennis, because you love the sport and try to be the best you can.
