Six-time Grand Slam champion Iga Swiatek advanced to the US Open fourth round on Saturday by defeating 25th-seeded Marie Bouzkova 7-6 (3), 7-6 (3) in a two-hour and 27-minute match, according to tournament reports. Swiatek won two tiebreaks in a single match for the first time in her career, setting up a clash against Zheng Qinwen.
Physical Battle and Hard-Fought Tiebreaks
The match tested both competitors through long baseline exchanges and challenging wind conditions. According to post-match comments reported by outlets, Swiatek noted that the contest grew physical as Bouzkova retrieved numerous balls.

“It got pretty physical,” Swiatek said, as reported by tournament coverage. “[There were] many long rallies, and sometimes I had to attack many times because Marie was defending really well and getting every ball back.”
Swiatek overcame early breaks in both sets. Bouzkova served for the opening set at 6-5 before Swiatek forced a tiebreak, where a double-fault from the Czech player handed Swiatek a crucial mini-break. In the second set, Bouzkova held three set points while leading 6-5, but Swiatek erased them—including saving one with a volley winner—before dominating the second tiebreak 7-3.

Statistical Breakdown of the Victory
Swiatek experienced fluctuations on her serve, winning just 60% of her first-serve points and suffering five breaks of serve, according to match statistics. However, her aggressive net play and baseline execution compensated for the service wobbles.
The Polish player converted 15 of 17 points at the net and fired 35 winners compared to Bouzkova’s 20. Swiatek also targeted Bouzkova’s second serve, winning 64% of those points to secure five breaks of her own.
Swiatek is seeking to cap an erratic season with a second US Open crown, having recently reached her first final of the year and captured the title in Toronto.
Fourth-Round Showdown Against Zheng Qinwen
The victory secures a fourth-round meeting between Swiatek and 2024 Olympic gold medalist Zheng Qinwen. According to tournament coverage, Zheng engineered a remarkable comeback against 22nd-seeded Madison Keys, rallying from a 5-0 deficit in the final set and saving a match point to win 1-6, 7-6 (3), 7-5.
Swiatek holds a 7-1 head-to-head advantage over Zheng, with her sole loss to the Chinese player occurring at the Paris Olympics. Swiatek also carries an undefeated 15-0 record against qualifiers and lucky losers at Grand Slam tournaments.
