Rounds are the round each match was played in, not a ladder: a player enters a 32-draw straight in R32, and team events (United Cup, Davis Cup) are not played through a draw at all — those have their own row. Ranking bands use the opponent's ranking on match day and are cumulative: top 100 includes top 10.
Surface record by season
Each cell is one season on one surface: the number is wins–losses, the colour is the win rate. Carpet is counted as indoor hard.

Season statistics
Each stat is stored as a value–count pair, so seasons can be added together and the rate is always value ÷ count.
2026 season · 2 games summed across the range
| Stat | Value | Count | Rate |
|---|---|---|---|
| Aces | 3 | 2 service games | 1.5 / game |
| Double faults | 6 | 2 service games | 3.0 / game |
| 1st serve in | 91 | 147 serve points | 62% |
| 1st-serve points won | 59 | 91 1st serves in | 65% |
| Break points saved | 11 | 18 faced | 61% |
Value is what happened (aces hit, points won), count is how often it could (service games, points played). Adding seasons adds both — the rate is never averaged from percentages.
