Jang S.J.
01/Record by surface
17 starts on all surfaces. 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.
02/Round reached
| Stage | Entries ending here | Record at this round |
|---|---|---|
| Champion | 0 of 13 | |
| Quarterfinal | 1 of 13 | 0-1 in 1 |
| 2nd Round | 2 of 13 | 1-2 in 3 |
| 1st Round | 10 of 13 | 3-10 in 13 |
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.
03/By level
| Level | Starts | Hard | Clay | Grass | Titles |
|---|---|---|---|---|---|
| International | 17 | 4-13 | none | none | 0 |
04/By season
| Season | Starts | Hard | Clay | Grass | Finals | Titles | Rank, newest row |
|---|---|---|---|---|---|---|---|
| 2018 | 2 | 0-2 | none | none | 0 | 0 | 204 |
| 2017 | 4 | 0-4 | none | none | 0 | 0 | 153 |
| 2016 | 5 | 2-3 | none | none | 0 | 0 | 171 |
| 2015 | 2 | 0-2 | none | none | 0 | 0 | 212 |
| 2014 | 1 | 0-1 | none | none | 0 | 0 | 215 |
| 2013 | 3 | 2-1 | none | none | 0 | 0 | 540 |
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 Jabeur O., 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, 2013 to 2018, 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.
