My pick: Elise Mertens to advance · locked 2026-08-28 06:40 UTCPrediction
Mertens. The 23rd seed is the tour's metronome — a 25–16 season, 229 career hard-court wins, a 2020 quarter-final here, and a game that has finished inside the top 40 for nearly a decade without ever donating a first-round shock. Quevedo at 20 is the draw's least-documented entrant: No. 107 with a 14–8 season built below tour level and a US Open debut in front of her. The Belgian's pattern against newcomers is unvarying and effective — depth, patience, and the quiet accumulation of every loose point until the scoreboard has drifted out of reach. The youngster's ceiling is unknown, which is the romantic case; the known quantities are all on one side. Mertens in two.
The case for Elise Mertens
78% to winMertens has spent a decade converting exactly this fixture: 229 hard-court wins, a quarter-final here, and the tour's most reliable percentage game. Debutantes beat top-25 seeds when the seed brings errors; Mertens does not bring errors.
The case for Kaitlin Quevedo
22% to winQuevedo arrives unscouted with a winning season and house money — the classic profile of a debutante who plays over her head for an afternoon. Mertens's pace-less consistency gives a free swinger time to work; at 20, fearlessness is a weapon that occasionally beats craft.
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
- Mertens's 2020 quarter-final anchors a decade of US Open consistency — she has been the tour's steadiest seed of her tier for years.
- Quevedo, 20, is making her US Open main-draw debut ranked No. 107 — among the least tour-tested entrants in the field.
- First meeting; the winner faces Timofeeva or a qualifier in the Round of 64.
Head to head
Never met — a decade of tour craft against a debut. The scouting asymmetry is total: Mertens has no film on Quevedo, and Quevedo has years of film on Mertens.

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. This one profiles as a field-court match. (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 between the tour's most predictable excellence and its least-known newcomer: Mertens has made a career of being exactly as good as advertised, which for a debutante like Quevedo is either a clear roadmap or a closed door. This section of Rybakina's quarter stays navigable through the weekend — the winner's Round of 64 forms from a qualifier-heavy pocket. Sunday through Tuesday; $140,000 to the loser.
