New York: 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.
