01/Record by surface
35 starts on all surfaces. A count, not a record: the three records above are never added.
02/Round reached
| Stage | Entries ending here | Record at this round |
|---|---|---|
| Champion | 0 of 25 | |
| Semifinal | 1 of 25 | 0-1 in 1 |
| Quarterfinal | 1 of 25 | 1-1 in 2 |
| 4th Round | 1 of 25 | 0-1 in 1 |
| 3rd Round | 0 of 25 | 1-0 in 1 |
| 2nd Round | 3 of 25 | 3-3 in 6 |
| 1st Round | 19 of 25 | 5-19 in 24 |
An entry is one tournament in one season; its stage is the last round the draw shows him in, and a champion’s is the trophy. The record at a round counts matches started at that round, so a walkover moves him on without a line here.

04/By season
| Season | Starts | Hard | Clay | Grass | Finals | Titles | Rank, newest row |
|---|---|---|---|---|---|---|---|

| 2025 | 9 | 3-4 | none | 1-1 | 0 | 0 | 102 |

Each season is the same count over that season’s matches alone, each surface with its own starts. A season with a start on no grass court says none rather than 0-0. December openers file to the season they open. Finals counts the finals that crowned a champion, a walkover final among them, so Titles is a subset of it and a final lost shows in the gap; the surface columns count starts, which a walkover is not.
05/Head to head
A record, never a share: the most-met opponent is Khachanov K., 0-2 in 2 meetings. A percentage of meetings is a win probability wearing a hat, and this section prints none. Meetings are matches started; a walkover between the two is noted and counted in neither column.

Main-draw singles on the tour, 2021 to 2026, counted from the match rows. A match ended by retirement keeps the sets that were completed and is marked; a walkover is listed with no score and enters no count. Ranks are the tour’s ranking on the day of the match. No serve statistic appears on this page: the one archive that carries them is licensed for non-commercial use only. The ATP record runs through Aug 29, 2026.
