Swiatek Wins Two Tiebreaks to Reach US Open Fourth Round

What happened

Iga Swiatek advanced to the fourth round of the 2026 US Open by defeating Marie Bouzkova 7-6(3), 7-6(3) on Saturday in New York. The official US Open tournament report says the No. 8 seed won both tiebreaks by the same score and saved three set points in the second set. The result kept Swiatek's campaign efficient on paper: she has won all three of her matches at this tournament in straight sets.

The scoreline also shows why this was a sterner examination than a routine two-set victory. Bouzkova forced a tiebreak in each set and came within a point of extending the match on three occasions late in the second. Swiatek's ability to erase those chances, then take command of another breaker, was the decisive feature of a match in which there was little separation between the players across the regulation games.

Why it matters

Grand Slam progress is often measured not only by how dominant a player looks, but by whether they can solve difficult moments without allowing a match to expand into a third set. Swiatek did that twice against Bouzkova. She protected her place in the draw while avoiding the physical and mental cost of a deciding set, an important consideration as the tournament moves into its second week.

The victory also gave Swiatek three consecutive two-set wins in New York. That puts her alongside fellow Saturday winners Coco Gauff and Mirra Andreeva, who also reached Round 4 without dropping a set, according to the US Open's recap. Their progress stood in contrast to an upset-heavy day in which top-10 seeds Taylor Fritz, Flavio Cobolli and Amanda Anisimova were eliminated.

Tournament impact

Swiatek's survival preserves one of the leading contenders in the women's draw at a moment when other seeded players are falling. The ranking beside her name makes her a favorite in many matchups, but Bouzkova demonstrated how quickly that status can be tested. Two close sets required Swiatek to produce her clearest tennis when the scoreboard applied maximum pressure.

For the rest of the field, the important signal is that Swiatek has not yet been pushed to a deciding set. For Swiatek, the useful lesson is more specific: even when an opponent holds set points and repeatedly stays level, she can still close the door in the tiebreak.

What to watch

The fourth round will raise the stakes and the quality of opposition again. Swiatek's baseline control and return game will remain central, but Saturday's match underlined the value of first-strike execution on the biggest points. Her next test will show whether the close calls against Bouzkova sharpened her level or exposed openings a later-round opponent can exploit.
