Watch US Open — Day 5 Third Round Free.

What's at Stake

The third round at Flushing Meadows represents the critical gateway to the second week of the US Open, where the pressure intensifies and the margin for error shrinks. For the top seeds, navigating this round is essential to keep their championship aspirations alive and secure vital ranking points. For the lower-ranked competitors and qualifiers, a victory here offers a career-defining opportunity to reach the round of 16 on one of tennis's grandest stages.

Form Guide

As the tournament enters its fifth day, the remaining players have successfully navigated two rounds of intense best-of-five or best-of-three matches, adjusting to the demanding late-summer heat and humidity of New York. Those who secured quick, straight-sets victories in the opening rounds hold a distinct physical advantage over competitors who have already endured grueling four- or five-set battles. Momentum is building rapidly, with early-round rust now replaced by sharp baseline rhythm and dialed-in serving numbers.

Key Players to Watch

• The Defending Champions — keeping their composure under the immense pressure of defending title points on the fast hard courts.
• The Hard-Court Specialists — utilizing their flat groundstrokes and aggressive baseline positioning to dictate the tempo of the rallies.
• The Breakthrough Underdogs — riding the wave of crowd support as they attempt to pull off major upsets against seeded opponents.

Prediction

Expect the highly seeded favorites to assert their dominance in the majority of the day's matchups, as their experience in managing best-of-five-set pressure typically shines through in the third round. While we are likely to see at least one highly competitive five-set thriller or a major upset on the show courts, the established top-ten players should largely secure their spots in the second week. A safe expectation is for the top seeds to advance in relatively comfortable four-set or straight-set victories as they fine-tune their games for the business end of the tournament.
