Gauff Faces Sonmez at US Open with New Serve

Coco Gauff has returned to the US Open for its 2026 edition, where she is scheduled to face Sonmez on Day 3 of the tournament.

Experts have already offered a prediction for the outcome of the match, reflecting the attention Gauff continues to attract at one of tennis's most prestigious events.

The US Open holds particular significance for Gauff, as it is the venue where she previously made personal tennis vows — commitments about her development and career goals.

According to reports, those vows are still propelling her forward, suggesting they continue to shape her approach to the sport years later.

Heading into this year's tournament, much of the discussion around Gauff has centered on her revamped serve, a technical overhaul of a stroke that has historically been scrutinized as a weak point in her game.

The serve, which begins every point in tennis, can be decisive at the elite level, where small technical differences often separate winners from losers.

Gauff herself has described the changes positively, saying the new serve 'feels good,' a comment suggesting genuine satisfaction rather than mere optimism.

She has also said the improved shot is fueling her confidence as she prepares for the demands of a Grand Slam campaign.

Confidence is widely regarded by coaches and sports psychologists as a critical factor in high-pressure competition, particularly in a sport as mentally demanding as tennis.

Whether the technical adjustments translate into results will be closely watched, starting with her Day 3 match against Sonmez.

Analysts and fans alike will be assessing not only the outcome of the match but also whether Gauff's serve performs reliably under tournament pressure.

The match represents an early opportunity to evaluate the practical impact of Gauff's off-season work, ahead of what many expect to be a demanding tournament for the American star.
