Serena thru’, Murray out

Serena Williams continued her hunt for a record seventh US Open title with a straight-sets win on Thursday as Andy Murray crashed out in the second round at Flushing Meadows.

Williams, the tournament's third seed, dispatched unseeded Russian Margarita Gasparyan 6-2, 6-4 under the roof of a near-empty Arthur Ashe Stadium on a wet New York evening.

The 38-year-old closed out the first set with ease before a slight wobble in the second when she was broken twice by Gasparyan, before progressing into the third round.

"I'm just happy to get through it and try to focus on the next round," said Williams, who will take on 2017 champion Sloane Stephens in the last 32.

Williams is seeking a record-equalling 24th singles Grand Slam title at a subdued, spectator-free Billie Jean King US National Tennis Center in New York.

In the men's draw Andy Murray, slumped to a 6-2, 6-3, 6-4, defeat against a dominant Felix Auger-Aliassime.

The 15th seed Canadian smashed 24 aces and 52 winners in a one-sided affair that saw Murray muster just two and nine respectively.

"I just felt like everything was coming in, my toss, my rhythm. Everything was going well through the whole match," said Felix Auger-Aliassime.

In early men's matches, second seed Dominic Thiem celebrated his 27th birthday with an easy straight-sets win against Sumit Nagal, who became the first Indian man since 2013 to reach the second round of a Grand Slam.
