All four matchups in Arthur Stadium will feature American talent on Monday. 

Madison Keys will kick things off with the first round tussle with Mexico’s Renata Zarazu, with Francis Tiafoe taking the reins from there. The two-time semifinalist battles Japan’s Yoshihito Nishioka. 

The night session will sizzle as 45-year-old Venus Williams, making her 25th US Open appearance, takes on last year’s semifinalist Karolina Muchova, while bomb-serving Reilly Opelka will take a crack at 2022 Champion Carlos Alcaraz in the nightcap.

Alcaraz has won 34 of his last 36 hard court matches, and is fresh off the Cincinnati title, but Opelka, ranked 67, has been on the rise of late, and has 23 wins under his belt already in 2025.

Youth Brigade on Armstrong

A pair of highly talented 18-year-olds will take the court on Louis Armstrong on Monday as Canada’s Victoria Mboko gets things started with her US open main draw debut.

24th-ranked Mboko, who won her first WTA title in Montreal earlier this month will face two-time major champion Barbora Krejcikova. Talk about trial by fire on the grand slam stage.

In the last match of the evening, Mirra Andreeva will face hard serving American Alycia Parks. Talented Andreeva has reached the second week of all three Grand Slams thus far this season, but she has never been past the second round in two previous appearances in New York.

Petra’s Last Stand? 

All eyes will be on two time Wimbledon champion Petra Kvitova, 35, as she faces Frenchwoman Diane Parry and what could be her last ever match on tour.

The pair will clash in the first match of the day, starting at 11 AM, on Grandstand.

World No.543 Kvitova, who owns 31 singles titles, has not lost in the first round in Queens since 2011. She is 34-14 lifetime at the US Open.
