The 2023 U.S. Open winner comes into this year's edition of the event red-hot. She made it to the semifinals at both Wimbledon and the National Bank Open in Canada, and then won the Cincinnati Open in her most recent tournament, defeating the likes of Marie Bouzkova, Marta Kostyuk, and Jessica Pegula en route to winning the title.

She's now aiming to win her second U.S. Open title and she'll begin her journey with a match against Zeynep Sonmez on Tuesday night. Let's dive into the odds and my best bet for this match.

Zeynep Sönmez vs. Coco Gauff: History and U.S. Open Performance

These two have never faced each other at the professional level.

Zeynep Sönmez

The 24-year-old is looking to make her first deep run at a Grand Slam. Her best career finish is third round appearances at the 2025 Wimbledon and this year's Australian Open. Her best finish at the U.S. Open was a second-round appearance last year.

Coco Gauff

Gauff won the U.S. Open in 2023, her first career Grand Slam victory. Since then, she has made it to the fourth round at this tournament in both 2024 and 2025, failing to make it to the quarterfinals. This season, her best Grand Slam finish was a semifinal appearance at Wimbledon.

Zeynep Sönmez vs. Coco Gauff Prediction and Best Bet

I do not doubt that Coco Gauff will win this match, but Zeynep Sonmez may put up a respectable fight in this spot. She has shown competence against higher-ranked players so far this season, including eight wins against women ranked in the top 50. Her highlights include a win against Ekaterina Alexandrova and Jasmine Paolini.

I'll back Sonmez to cover the game spread as the underdog in this first round match.
