Career serve & return
Absolute totals across the 0 matches we have on record. Green is Lien, grey is the same stat by the players they faced.

Counted from the match statistics we hold, season by season — the cards above are career totals from our data provider, so the two can differ by a few tenths. Seasons with fewer than three matches on record are left out.

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 | Hard | Clay | Grass | I.hard | Total |
|---|---|---|---|---|---|
| 2026 | 4–3 | 11–10 | · | 0–2 | 15–15 |
| 2025 | · | 1–1 | · | 1–1 | 2–2 |
| Career | 4–3 57% | 12–11 52% | · | 1–3 25% | 17–17 50% |
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 | 5 | 2 service games | 2.5 / game |
| Double faults | 1 | 2 service games | 0.5 / game |
| 1st serve in | 107 | 154 serve points | 69% |
| 1st-serve points won | 65 | 107 1st serves in | 61% |
| Break points saved | 17 | 23 faced | 74% |
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.
