A double fault is two missed serves on the same point — a point handed over without the returner playing a ball. This board ranks the cleanest servers on tour: fewest double faults per match, best first.
Double faults are the one serving statistic entirely inside the server's control, so the leaders here are a read on nerve and on second-serve construction rather than on power. Note the direction: this ranks the FEWEST, so the player at number one is the tidiest server, not the most error-prone.
Adam Walton leads the ATP with 1.2 double faults per match in 2026, measured over 17 qualifying matches — the fewest of any qualified ATP player this season. Brandon Nakashima (1.3) and Alejandro Davidovich Fokina (1.4) are next. 89 ATP players qualify, and the median of that field is 2.9.
39 further qualified ATP players are outside the top 50; the full field is sortable in the ATP stat explorer on Stat Leaders.
Karolina Muchova leads the WTA with 1.4 double faults per match in 2026, measured over 44 qualifying matches — the fewest of any qualified WTA player this season. Jessica Pegula (1.8) and Renata Zarazua (1.8) are next. 80 WTA players qualify, and the median of that field is 3.8.
30 further qualified WTA players are outside the top 50; the full field is sortable in the WTA stat explorer on Stat Leaders.
Double faults per match is the mean of a player's per-match double-fault counts, over the matches where a double-fault count was recorded.
A player qualifies for this board with at least 15 singles matches in the 2026 pool and at least 15 of those matches carrying this statistic. The floor is half the busiest schedule on tour, capped at 15 — a flat 15 would leave the board empty until roughly April, when the pool has barely filled. The Matches column on every row is that player's own denominator, so a number taken over a thin sample is visible as one rather than hidden behind a rank. A tour section is withheld entirely below 25 qualified players.
Figures cover Grand Slam, 1000- and 500-level singles matches in 2026, on every surface. 250-level and lower-tier events are not counted, so a player's totals here run below their full-season numbers — which is also why this page ranks a per-match or per-point RATE rather than a season total. A total drawn from a partial pool would be wrong in a way a rate is not.
Double-fault counts travel with ace counts on the same scoreboard feed, so their coverage matches. In the 2026 pool this statistic is recorded for 2,958 of the 3,040 ATP matches (97%) and 2,934 of the 3,298 WTA matches (89%).
Ranks and values on this page are computed over the same pool, so the ordering and the numbers beside it always agree. Drop Shot is not the ATP or the WTA and these are not official tour statistics: they are aggregated from our own match feed, and where a match did not report a statistic it contributes nothing to either the numerator or the denominator.
