My pick: Karolina Muchova to advance · locked 2026-08-28 05:50 UTCPrediction
Muchová. Few players arrive at any major carrying more current New York equity: the seventh seed was a semi-finalist here in 2024, a Wimbledon finalist last month, and on Wednesday night she stood on Arthur Ashe lifting the mixed doubles trophy with Jakub Menšík. Her 35–9 season is the record of a player whose all-court elegance finally has a healthy body underneath it. Kraus, the Austrian No. 86, is a solid professional playing her first US Open, with a 15–23 hard-court career that suggests the surface tolerates rather than embraces her. Muchová's variety — the sport's best mid-rally improvisation — against a debutant on the wrong surface is as one-sided as tennis aesthetics get. Straight sets, with highlights.
The case for Karolina Muchova
85% to winMuchová is the section's class by a wide margin: a 2024 semi-final here, a Wimbledon final in July, a 35–9 season, and game-style superiority in every category — serve variety, transition, touch, tactics. She has also spent two extra weeks winning matches on these exact courts. The gap is not a matchup question; it is a class question.
The case for Sinja Kraus
15% to winKraus has a winning season (17–14) and the freedom of a debutant nobody expects anything from; Muchová's transcendent weeks have occasionally been followed by flat ones, and a mixed doubles campaign that ended Wednesday leaves less recovery margin than a normal seed's. Make her play a third set and the fatigue question becomes real.
Both cases written 2026-08-28, before the first ball — frozen into the record exactly as written, whatever the result. The percentages are mine, quoted to a decimal because false precision is funnier — and tennis has no draw to hide the rounding in.

The briefing
Storylines
- Muchová won the mixed doubles title here on Wednesday night with Jakub Menšík — she opens her singles four days later as the seventh seed.
- Her July was an all-Czech Wimbledon final (lost to Nosková); her 2024 US Open was a semi-final — the deepest current New York résumé among the women's seeds outside the top five.
- Kraus, ranked No. 86, is playing her first US Open main draw — her first look at a top-ten opponent at a major.
Head to head
Never met — Muchová's injury-punctuated prime and Kraus's steady climb had no reason to intersect until this draw.

Watch: Opening-round coverage starts Sunday at 11 a.m. ET across ESPN, ESPN2 and ABC, with ESPN Deportes in Spanish — and every court streams in the ESPN app, including a whip-around channel for the early rounds. (ESPN press-room release and listings, as of 2026-08-27)
Court & schedule: Not yet assigned — the US Open posts each day's order of play the evening before, so day-one courts land the night of 29 August. The reigning mixed doubles champion's singles opener profiles for Armstrong or Ashe. (US Open order-of-play release cadence, as of 2026-08-27)
Weather: The opening window looks kind: mostly sunny and 85–86°F Sunday and Monday, with thunderstorm chances only creeping in on Tuesday. Ashe and Armstrong close their roofs if the sky turns; the field courts wait it out. (National Weather Service New York forecast, as of 2026-08-27)
Venue: USTA Billie Jean King National Tennis Center, Flushing Meadows, New York — hard.
At this Stage
Round of 128, and the grounds' reigning co-champion returns to the singles business: Muchová's mixed doubles title with Menšík wrapped Wednesday on Ashe, and her real campaign — a top-five-caliber season stuck behind a seventh seeding — starts here. The section rewards early efficiency: her projected path stays gentle until the second week, where the draw's Czech theme (Nosková, the Wimbledon final rematch possibility) hangs over everything. Kraus gets the honor and the problem of the first look. Sunday through Tuesday.
