01/Record by surface

each with its own count; nothing here is blended

Hard

14-23

37 starts, 2017 to 2025. 38 of 88 completed sets won

Clay

8-10

18 starts, 1 ended by retirement, 2017 to 2025. 18 of 39 completed sets won

Grass

1-5

6 starts, 2017 to 2025. 3 of 14 completed sets won

61 starts on all surfaces, 1 ended by retirement and kept, 1 walkover listed and not counted. A count, not a record: the three records above are never added.

02/Round reached

38 tournaments entered

Stage	Entries ending here	Record at this round
Champion	0 of 38
Semifinal	2 of 38	0-2 in 2
Quarterfinal	2 of 38	2-2 in 4
2nd Round	14 of 38	3-14 in 17
1st Round	20 of 38	18-20 in 38

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 Allertova D., 1-1 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.

The 50 most recent of 62 rows. The older rows are in every count on this page and are printed on other pages, not dropped: each one is on one of the 56 head-to-head pages linked above, which carry every meeting, and on its tournament’s page.

Main-draw singles on the tour, 2017 to 2025, 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.
