Barrientos N.
01/Record by surface
4 starts on all surfaces. A count, not a record: the three records above are never added. The record begins with the 2013 season; his earlier matches are not in it.
02/Round reached
| Stage | Entries ending here | Record at this round |
|---|---|---|
| Champion | 0 of 4 | |
| 1st Round | 4 of 4 | 0-4 in 4 |
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.
03/By level
| Level | Starts | Hard | Clay | Grass | Titles |
|---|---|---|---|---|---|
| ATP250 | 4 | 0-1 | 0-3 | none | 0 |
04/By season
| Season | Starts | Hard | Clay | Grass | Finals | Titles | Rank, newest row |
|---|---|---|---|---|---|---|---|
| 2022 | 1 | 0-1 | none | none | 0 | 0 | 354 |
| 2015 | 1 | none | 0-1 | none | 0 | 0 | 293 |
| 2014 | 1 | none | 0-1 | none | 0 | 0 | 329 |
| 2013 | 1 | none | 0-1 | none | 0 | 0 | 293 |
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
| Opponent | Meetings | Record | Hard | Clay | Grass | Span | |
|---|---|---|---|---|---|---|---|
| Bemelmans R. | 1 | 0-1 | none | 0-1 | none | 2013 | Every meeting |
| Hernandez A. | 1 | 0-1 | 0-1 | none | none | 2022 | Every meeting |
| Polansky P. | 1 | 0-1 | none | 0-1 | none | 2014 | Every meeting |
| Sugita Y. | 1 | 0-1 | none | 0-1 | none | 2015 | Every meeting |
A record, never a share: the most-met opponent is Bemelmans R., 0-1 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 2022, 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.
