01/Record by surface
29 starts on all surfaces, 1 ended by retirement and kept. 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 23 | |
| Quarterfinal | 1 of 23 | 0-1 in 1 |
| 2nd Round | 4 of 23 | 1-4 in 5 |
| 1st Round | 18 of 23 | 5-18 in 23 |
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.

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 Baez S., 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, 2018 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.
