Serena, Sharapova to clash in US Open first round blockbuster

Serena Williams will begin her quest for a seventh US Open title and record-tying 24th Grand Slam victory against long-time rival Maria Sharapova in the US Open women's singles draw unveiled Thursday.

Williams has dominated the Russian star in their head-to-head rivalry, winning 19 times with only two defeats, including their past 18 meetings, most recently at the 2016 Australian Open quarter-finals, although Sharapova advanced by walkover against Williams in the fourth round at Roland Garros last year.

Eighth-ranked Williams is looking to match the all-time record of 24 Grand Slam singles titles won by Margaret Court when the year's final major championship gets under way Monday.

The 37-year-old American has dropped her past three Grand Slam finals appearances, including last month to Simona Halep at Wimbledon and last year to Japan's Naomi Osaka at the US Open after a controversial game penalty for her tirade at umpire Carlos Ramos.

Tournament officials have said Ramos will not work any matches involving Serena or Venus Williams, who could not face her sister until the semi-finals, being in the same draw quarter as Czech third seed Karolina Pliskova.

Serena was placed into the same quarter as Australian second seed Ashleigh Barty, the reigning French Open champion whose first match is against 77th-ranked Zarina Diyas of Kazakhstan.

Top-seeded Osaka opens against Russia's 93rd-ranked Anna Blinkova and could face a third-round date against 15-year-old American Coco Gauff, who eliminated Venus Williams in the first round at Wimbledon in a run to the last 16 in her Grand Slam debut.

Romania's fourth-seeded Halep, coming off her second Grand Slam title, opens against a qualifier and could face a semi-final against Osaka, who defends a Slam crown for the first time.

"I'm looking forward to the experience," Osaka said.

"Everyone knows I love it here."
"I'm here and I feel like I'll be able to play."
"I like to focus my attention on that one."
