Marino into U.S. Open 3rd round after firing 13 aces against shaky Ukrainian Snigur

Vancouver's Rebecca Marino advanced to the third round of the U.S. Open with a 6-3, 7-6 (5) win over Ukraine's Daria Snigur on Wednesday.

Marino fired 13 aces in the match to Snigur's one and won 74 per cent of first-serve points.

Marino took advantage of some spotty play from Snigur, who had 48 unforced errors, including one while facing match point.

The Canadian broke Snigur three times on eight chances and saved five of the seven break points she faced.

Marino advanced to the third round of a Grand Slam for the second time in her career, and the first time in over a decade. She advanced to the third round of the 2011 French Open.

Marino will next face China's Zhang Shuai.

Later today, 2019 U.S. Open champion Bianca Andreescu was slated to take on 15th seed Beatriz Haddad Maia of Brazil and 2021 runner-up Leylah Fernandez, seeded 14th, was scheduled to face Russia's Ludmilla Samsonova.

In men's action, sixth seed Felix Auger-Aliassime of Montreal faced Jack Draper of Britain.

In women's doubles, the fifth-seeded pair of Ottawa's Gabriela Dabrowski and Giuliana Olmos of Mexico were set to play a first-round match against Peyton Stearns and Ashlyn Krueger of the United States.

The last two women's champions were already out of the U.S. Open and now one of last year's semifinalists is gone.

Top players are falling fast in Flushing Meadows, and Serena Williams can topple another Wednesday night.

Hours before Williams was set to face No. 2 seed Anett Kontaveit, third-seeded Maria Sakkari was ousted 3-6, 7-5, 7-5 by Wang Xiyu of China in the second round.
