Saturday’s action at the Billie Jean King National Tennis Center delivered spades full of drama. Whilst top seed Alexander Zverev cruised through his third-round clash, American hopes took a savage blow as Taylor Fritz suffered a devastating five-set collapse, and the women’s draw witnessed a string of comeback victories that had Flushing Meadows roaring.

Zverev stamps authority, Fritz fumbles

The German machine rolled on. Top seed Alexander Zverev dispatched Chile’s Alejandro Tabilo 6-2, 7-6 (7/2), 6-2 in a clinical display. The world number one barely broke sweat. This is the Zverev that arrived in New York with a point to prove.

But if Zverev’s progression was routine, Taylor Fritz’s exit was anything but. The ninth seed squandered a two-set lead against Argentina’s Francisco Cerundolo, capitulating 3-6, 4-6, 6-3, 6-4, 6-4 in a gut-wrenching collapse. Fritz looked in complete control through the opening two sets. The Argentine’s resilience and tactical shift completely bamboozled the American, who couldn’t stem the tide as his Grand Slam dream evaporated in front of a stunned home crowd.

The upset theme continued when Belgium’s Alexander Blockx stunned fifth seed Flavio Cobolli 6-7 (4/7), 6-3, 6-0, 6-3. After dropping a tight opening set, the 28th seed didn’t drop another, dismantling the Italian.

Five set thrillers light up Flushing Meadows

Saturday belonged to the grinders. Three men’s matches went the distance, each delivering edge-of-your-seat tension.

Botic van de Zandschulp saved his tournament with an extraordinary five-set escape against Belgium’s Zizou Bergs, prevailing 3-6, 7-6 (7/3), 4-6, 7-6 (8/6), 6-3. The Dutchman won two tiebreaks by the narrowest of margins, showing the mental fortitude required at this level.

American teenager Learner Tien announced himself on the big stage with a statement victory over Czech 17th seed Jakub Mensík. The 14th seed battled through 6-3, 1-6, 6-7 (2/7), 6-3, 6-4, showcasing the kind of resilience that suggests this youngster could be a genuine contender in the years to come.

France’s Arthur Gea completed another five-set epic, outlasting American Michael Zheng 7-6 (9/7), 3-6, 4-6, 6-3, 6-2 in a match that swung back and forth before Gea found his rhythm in the decider.

Elsewhere, Karen Khachanov marched into the fourth round with a straightforward 6-3, 6-2, 6-4 victory over Benjamin Bonzi, whilst Italy’s Luciano Darderi eased past Australian Dane Sweeny 6-4, 6-3, 6-3.

Women’s draw: The favourites survive, but not without scares

Fourth seed Coco Gauff kept American hopes alive with a composed 6-3, 6-4 victory over Spain’s Cristina Bucsa. .

Iga Swiatek ground out a hard-fought victory that was far tougher than the eighth seed would have wanted. The Polish star needed two tiebreaks to see off Marie Bouzková 7-6 (7/3), 7-6 (7/3), showcasing her champion’s mentality when the straightforward victory refused to materialise.

Second seed Elena Rybakina also needed a tiebreak but ultimately had too much firepower for Ukraine’s Yuliia Starodubtseva, winning 7-6 (8/6), 6-3. The Kazakh’s serve proved the difference, as it so often does.

But the match of the day belonged to China’s Zheng Qinwen, who produced a stunning comeback to stun 22nd seed Madison Keys. After dropping the opening set 1-6, Zheng clawed her way back into the contest, winning two dramatic sets 7-6 (7/3), 7-5. Keys will be kicking herself for letting this one slip away after such a dominant start.

Naomi Osaka’s Grand Slam renaissance continued with a three-set victory over Belgium’s Elise Mertens. The 13th seed prevailed 6-3, 3-6, 7-5 in another match that went down to the wire, proving that the former world number one’s competitive fire still burns bright.

Upsets and emerging talent

Russia’s Mirra Andreeva, the fifth seed, dispatched Czech Nikola Bartunková 6-2, 7-6 (7/5), whilst Austria’s Anastasia Potapova pulled off a significant upset, dumping out 10th seed Amanda Anisimova 6-2, 7-5. The American will rue missed opportunities against the 24th seed.

American teenager Iva Jovic continued her impressive run, edging past Philippines’ Alexandra Eala 7-5, 3-6, 7-5 in a battle of emerging talents. The 14th seed showed composure beyond her years to close out the decider.

As the tournament enters its second week, the draw is thinning and the stakes are rising. With Fritz gone and Cerundolo surging, the men’s draw has been blown wide open. On the women’s side, the big names survived, but Saturday’s scares suggest that nothing can be taken for granted at this year’s US Open.
