My pick: Aryna Sabalenka to advance · locked 2026-08-28 04:35 UTCPrediction
Sabalenka. The world No. 1 opens her bid for a third straight US Open title — chasing an Open Era feat only Chris Evert and Serena Williams have managed here — against an opponent she has beaten twice without drama. Osorio is a genuine competitor whose 17–17 season and counterpunching craft keep scoreboards respectable, but the physics are unkind: Sabalenka's 40–8 year has been built on first-strike violence that Osorio's game absorbs rather than answers, and the two prior meetings (6-0 6-3, 6-4 7-5) map the range of likely outcomes fairly. The number one's early rounds here have occasionally wobbled under her own error count; that is the only route to interest. Straight sets, the second tighter than the first.
The case for Aryna Sabalenka
90% to winTwo-time defending champion, world No. 1, a 40–8 season, and 297 career hard-court wins: Sabalenka arrives as the most accomplished hard-court player in the women's field, and both prior meetings with Osorio ended in straight sets. Her serve-forehand combination is the heaviest opening statement in the draw.
The case for Camila Osorio
10% to winOsorio thrives as the underdog with nothing to lose — her speed and depth force the big hitters to supply their own rhythm, and Sabalenka's opening-round error counts have historically been her most vulnerable stat. Both previous meetings had competitive stretches; extending them a set further is the whole assignment.
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
- Sabalenka is chasing a third consecutive US Open title — an Open Era feat only Chris Evert and Serena Williams have managed here.
- She arrives at 40–8 having lost January's Australian Open final to Rybakina — New York is where her season's biggest defense lives.
- Sabalenka has won both prior meetings with Osorio in straight sets, on grass and clay; this is their first hard-court match.
Head to head
Sabalenka leads 2–0 — 6-0 6-3 at Wimbledon 2021 and 6-4 7-5 in Madrid 2023. Osorio's competitive second sets are the honest footnote; a won set is not among them.

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 defending champion traditionally opens the Sunday night session on Arthur 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 women's draw opens at its summit: the two-time defending champion, world No. 1, chasing the three-peat only Evert and Serena have managed here in the Open Era. Sabalenka's season — 40 wins, an Australian Open final, the top ranking never surrendered — makes her the tournament's reference point; everyone else's path is measured by where it crosses hers. Osorio gets the first measurement. The winner meets Zarazúa or a qualifier in the Round of 64. Women's first-round play runs Sunday through Tuesday.
