Result
Siniakova offered two break points in sixty-nine minutes, both in the same game. She broke at the start of both sets — the first on a Cocciaretto double fault, the second when a Cocciaretto second serve clipped the net cord and dropped out at 30-40 — and the only wobble came in the fourth game of the second set, when she double-faulted and lost serve for the only time. Cocciaretto held for 2-3 and won nothing after it; another double fault gave up the 2-5 game and Siniakova served it out from 40-0. She hit twenty-six winners to eleven and won 77% of her first-serve points, leaning on the backhand down the line. It is her first US Open singles win since 2022, after three straight first-round exits, and takes her singles record here to 6-11 — a fortnight in which she and Henry Patten had to qualify for the mixed doubles despite both being the doubles world No. 1, beat Djokovic and Sabalenka in the round of 16 and lost the quarter-final to Svitolina and Monfils.

At this Stage
Round of 128 with the sport's great specialist question attached: Siniaková owns more doubles silverware than entire nations and keeps proving the singles game never left. The winner draws Osaka or Zakharova in the Round of 64 — which converts this quiet fixture into an audition for the fortnight's showcase court. Cocciaretto's steadier singles year against the Czech's genius hands: pick your theory of tennis. Sunday through Tuesday.
What we know now
What I said beforehand
The preview, frozen before the first serve. Clearly dated, never rewritten — that's the deal that makes the pick worth anything.
Siniaková, narrowly. The world's premier doubles player — a champion at every major in that discipline — remains a stubbornly effective singles pro at 30: a 195–176 hard-court career, a 2–1 head-to-head over Cocciaretto, and hands at the net that convert defense into offense mid-rally like nobody else in the section. Her singles season is 15–16; Cocciaretto's 22–15 is the better year, and the Italian's clean baseline game won their only clay meeting. But both Siniaková wins came on faster surfaces, including a hard-court rout in Mérida, and her serve variety travels better than the Italian's rhythm hitting. She also banked extra court time here in the mixed doubles with Henry Patten during Fan Week. Siniaková in three.
The case for Elisabetta Cocciaretto
44% to winCocciaretto has the better season by seven wins, the sounder baseline architecture, and the fitness edge of a full-time singles schedule — Siniaková's doubles commitments split her weeks in half. The Italian won their most physical meeting, and rhythm hitters beat improvisers when the rallies stay long.
The case for Katerina Siniakova
56% to winSiniaková leads the head-to-head 2–1 with both wins on quicker courts, and her all-court improvisation is the style rhythm players least enjoy. The greatest doubles player of her generation does not lose the touch exchanges, and she spent Fan Week sharpening on these courts in the mixed with Henry Patten.
Both cases written 2026-08-28, before the first ball — frozen into the record exactly as written, whatever the result. The percentages are mine — opinions with a percent sign on. They add to 100 because tennis has no draw to hide the rounding in.
My locked pick: Katerina Siniakova to advance ✓ RIGHT
“Two of three in the head-to-head, both on quick courts, plus a Fan Week of match play here — genius hands travel.”

Storylines
- Siniaková — the world's No. 1-caliber doubles player with a career Grand Slam in the discipline — played the mixed doubles here two weeks ago with Henry Patten, falling to Svitolina and Monfils, who went on to the semi-finals.
- She leads Cocciaretto 2–1, including 6-1 5-7 6-0 on Mérida's hard courts in 2023.
- Cocciaretto's 22–15 season is the better singles year — the classic specialist-versus-generalist first-rounder.
Head to head
Siniaková leads 2–1: Cocciaretto took a three-set Budapest clay match in 2022; the Czech answered twice in 2023, on Mérida hard (6-1 5-7 6-0) and Bad Homburg grass. Quicker courts, quicker answers.
