What to Expect
Sinner enters this matchup with a powerful hard-court rhythm — characterized by aggressive groundstrokes, precision serving and the ability to sustain pressure on return games. His athleticism and depth from the baseline have made him one of the most consistent performers at Grand Slams this season.
Darderi, meanwhile, has captured attention with a resilient baseline game and tactical variety that can extend rallies and test elite ball-strikers. While he enters as the underdog, players of his profile thrive when they make Sinner work for every point.
This match boils down to consistency under pressure and early control. If Sinner asserts rhythm with his first serve and early forehand dominance, he’ll dictate pace. But if Darderi redirects rallies with depth and variation, we could see prolonged exchanges and tense momentum swings.
What to watch: Serve accuracy, break-point conversion and Sinner’s ability to stay aggressive without gifting cheap errors.

Tactical Preview
Keys brings one of the most fearsome serves and forehands in the women’s game — shotmaking that can abruptly flip momentum in her favor. Her aggressive baseline style thrives on dictating play and forcing quick defensive reactions.
Pegula, on the other hand, has built her reputation on consistency, court coverage and smart shot construction. She’s adept at turning defense into offense, constructing points with patience and precision rather than relying solely on power.
This clash is a fascinating contrast of styles: Keys’s punchy offense versus Pegula’s strategic placement. Expect deep rallies, sudden shifts in tempo and critical moments where patience outmaneuvers raw power — or vice versa.
Match focus: Points won on the first serve, depth behind groundstrokes, and momentum swings in key games.
Taylor Fritz vs. Lorenzo Musetti — Creativity Meets Controlled Power
The Storyline
In a compelling men’s singles encounter, Taylor Fritz takes on Italy’s Lorenzo Musetti, a matchup that juxtaposes steady aggression with artistic shot-making. Both players arrive at this crossroads with confidence and weapons that can unlock long rallies or swift winners.

Tactical Breakdown
Fritz brings powerful serving and a balanced baseline attack — consistent depth that minimizes short balls and opens up angles for big forehand winners. His high percentage on first serve and willingness to hold court position make him a strong contender in extended exchanges.
Musetti, in contrast, is known for creative variety and versatile shot-making, injecting slice, spin and sudden dropshots to throw rhythm off its axis. His game thrives on unpredictability and the ability to craft point patterns that unsettle even the best returners.
This matchup is a study in controlled aggression vs inventive flair. Fritz will look to maintain depth and apply pressure early, while Musetti will seek opportunities to redirect pace and manufacture openings with creative angles.
What to watch: How each player handles pressure points, break opportunities, and transitions from defense to offense.
