Kostova E.
01/Record by surface
22 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 15 | |
| 2nd Round | 7 of 15 | 0-7 in 7 |
| 1st Round | 8 of 15 | 7-8 in 15 |
An entry is one tournament in one season; its stage is the last round the draw shows her in, and a champion’s is the trophy. The record at a round counts matches started at that round, so a walkover moves her 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.

A record, never a share: the most-met opponent is Hibino N., 1-0 in 1 meeting. 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, 2014 to 2019, 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 WTA record runs through Aug 30, 2026.
