01/Record by surface
358 starts on all surfaces, 19 ended by retirement and kept, 3 walkovers listed and not counted. A count, not a record: the three records above are never added. The record begins with the 2013 season; her earlier matches are not in it.

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.
06/Head to head
A record, never a share: the most-met opponent is Pavlyuchenkova A., 5-3 in 8 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 361 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 178 head-to-head pages linked above, which carry every meeting, and on its tournament’s page.
Main-draw singles on the tour, 2013 to 2021, 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.
