Jannik Sinner continued his flawless start to the US Open day-5 with another straight-set victory, extending his streak of dominant performances. The defending champion and No. 1 seed has yet to drop more than three games in a set through two rounds. 

He now prepares for a tougher third-round clash against No. 27 seed Denis Shapovalov, with the possibility of meeting American No. 14 seed Tommy Paul in the fourth round.

World No. 2 Carlos Alcaraz has mirrored Sinner’s dominance, also winning his opening two rounds without losing a set. The two stars remain on a collision course, showing the same energy and sharpness that make them favorites for the title.

Big upsets shake men’s draw

Thursday delivered shocks in the men’s bracket. Swiss qualifier Leandro Riedi staged a stunning comeback from two sets down to upset No. 19 seed Francisco Cerundolo. 

Meanwhile, Poland’s Kamil Majchrzak toppled No. 9 seed Karen Khachanov in five sets, also rallying from two sets behind. With No. 5 seed Jack Draper withdrawing, the top half of the draw suddenly looks more open for Sinner and No. 3 seed Alexander Zverev.

Zverev cruises toward Semis

Zverev reinforced his status as a top contender with a straight-set win over Jacob Fearnley on Thursday night. Like Sinner, he has yet to lose a set, keeping alive the prospect of a blockbuster semifinal showdown between the top two European stars.

Iga Swiatek endured a tough three-set battle in her second-round match at Arthur Ashe Stadium. The women’s No. 2 seed had to dig deep to keep her championship hopes alive, avoiding what would have been the tournament’s biggest upset so far. 

Swiatek now faces No. 29 seed Anna Kalinskaya and will need sharper form if she is to capture her second US Open crown.

US Open 2025: Women’s doubles match

Two-time US Open champion Naomi Osaka looked in peak form on Thursday, breezing past American Hailey Baptiste in straight sets. 

The No. 23 seed has yet to drop a set in New York and is emerging as a serious challenger in Swiatek’s half of the draw. Osaka now meets No. 15 seed Daria Kasatkina in the third round.

Venus Williams secured her first women’s doubles victory at the US Open in over a decade, this time without her sister Serena. Partnering with Leylah Fernandez on Thursday, she defeated the sixth-seeded duo of Lyudmyla Kichenok and Ellen Perez 7-6 (4), 6-3.

Coco Gauff gave the New York crowd plenty to cheer about with a commanding straight-set win over Donna Vekic. The top American hope looked sharper than in her opener, and she now faces No. 28 seed Magdalena Frech. A potential fourth-round blockbuster against Naomi Osaka looms if both advance.
