🧾 Prediction Summary
This US Open second-round clash pits Turkish qualifier Zeynep Sonmez against third-seeded American Cori Gauff. Gauff enters as a massive favourite at 1.025 in the betting market, while Sonmez's path to an upset sits at 12.5. The bookmaker's centre handicap of 6.5 games reflects an expectation that Gauff will take this comfortably, likely dropping no more than five or six games across two sets. Gauff's explosive power off both wings, improved second-serve depth, and home-court confidence at Flushing Meadows make her a formidable opponent for a player ranked well outside the top fifty. Our prediction: Cori Gauff to win 6-3, 6-2 in straight sets, covering the 6.5-game handicap.

🔎 In-Depth Team Analysis
🔴 Zeynep Sonmez
Zeynep Sonmez earned her main-draw spot through the qualifying rounds, dropping just one set in three qualifying matches to demonstrate she can compete at Grand Slam level when focused. Her game is built on consistency and movement; she relies on heavy topspin forehands and a patient baseline strategy to draw errors from more aggressive opponents. Against a player of Gauff's calibre, however, Sonmez will need to elevate every shot to stay competitive.In the lead-up to New York, Sonmez's hard-court season has been modest — she reached the quarterfinals of one 125K event in the summer but lost in the first round of qualifying at two WTA main-tour tournaments. She has limited experience against top-ten opposition and has never faced Gauff before. The pressure of an American Grand Slam crowd and a draw featuring a local favourite represents perhaps the biggest stage Sonmez has competed on in her career.
- Strengths: Solid baseline consistency, good movement, heavy topspin forehand
- Weaknesses: Limited offensive firepower, second serve vulnerable to aggressive returners
- Recent form: 4 wins and 5 losses across last 9 hard-court matches; qualified here
- Home/neutral factor: No home advantage; Turkish crowd unlikely to be significant at Flushing Meadows
- Key to victory: Must vary pace and depth to disrupt Gauff's rhythm; any chance of an upset depends on a career-best return game
🔵 Cori Gauff
Cori Gauff arrives at the 2026 US Open as the third seed after a season that has seen her collect two titles, including a Premier-level hard-court event in August. Her game has matured markedly — the serve is more reliable, the forehand carries greater pace and penetration, and her court coverage remains exceptional. Playing on American soil at her favourite Grand Slam amplifies her intensity.Gauff's preparation for Flushing Meadows included a short grass swing followed by a tune-up tournament in Cincinnati where she reached the semifinals before retiring with minor cramping — no concern going into the Open. Her team has worked on shortening points against lower-ranked players to conserve energy through a best-of-three draw, and her first-serve points won this summer hover around 74 percent.
- Strengths: Elite return game, powerful two-handed backhand, outstanding court coverage, home crowd support
- Weaknesses: Occasional service yips under pressure; over-hitting when ahead in a set
- Recent form: 11 wins and 2 losses on hard courts in the summer; two titles
- Home/neutral factor: Strongly positive — American crowd, familiarity with New York conditions
- Key to victory: Aggressive return positioning to rush Sonmez off the back foot; closing out second set efficiently

The match takes place on Tuesday, 1 September 2026 at 15:00 ET (UTC-4) at Louis Armstrong Stadium inside the USTA Billie Jean King National Tennis Center in Flushing Meadows, New York. It is a second-round clash at the 2026 US Open Women's Singles event.
Cori Gauff is expected to win in straight sets with a scoreline of 6-3, 6-2. The Turkish qualifier Sonmez is unlikely to generate enough offensive pressure to disrupt Gauff's rhythm across the full match, though she may steal a few games with patient baseline tennis.
Gauff to win is priced at approximately 1.04, while Sonmez sits at around 11.00. The handicap line for Gauff at -6.5 games is priced at 1.85, and the under 18.5 games total sits at 1.85. Both players winning a set is priced at 4.50, reflecting the low probability of that outcome.
This will be the first-ever meeting between Zeynep Sonmez and Cori Gauff in a sanctioned professional match. There is no prior head-to-head history. The ranking gap of approximately 109 places and the vast difference in Grand Slam experience heavily favour Gauff.
The decisive battle is Gauff's return game against Sonmez's second serve. Gauff wins around 74% of her first-serve points and averages over eight break opportunities per hard-court match. If Sonmez's first-serve percentage drops below 50%, Gauff's aggressive return positioning will create constant pressure that Sonmez's defence cannot sustain.
In the United States, the match will be available on ESPN and ESPN+ as part of the US Open broadcasting package. Internationally, coverage varies by region — in Turkey, beIN Sports typically carries Grand Slam tennis. The official US Open YouTube channel may also offer highlights after the match concludes.
