Youth Wins On Day 1
As main draw matches at the Citi Open kicked off, youth reigned supreme.
Rising star Aryna Sabalenka announced her arrival by taking out last year’s Citi Open finalist and No. 3 seed Lauren Davis 7-5, 6-3. The 19-year-old Belarusian awaits the winner of Sabine Lisicki and qualifier Valentini Grammatikapoulou. Bianca Andreescu took advantage of her main draw wild card, defeating free-swinging Italian Camila Giorgi 5-7, 6-3, 6-4. At just 17 years old, it is Andreescu’s first win at a WTA International event.
No. 4 seed Julia Goerges, No. 5 seed Oceane Dodin and Andrea Petkovic also advanced.
Andreescu wasn’t the only wild card with a big win on Monday. Tommy Paul built on his quarterfinal run in Atlanta last week, outlasting fellow ATP Next Gen member Casper Ruud 3-6, 7-5, 3-0 before the Norwegian retired with an injury. The 20-year-old from Greenville, South Carolina, will face No. 7 seed Lucas Pouille in the second round.
Rhode Island native Jared Donaldson, 20, continued his strong showing this season with a three-set victory over former top-30 player Dudi Sela. Donaldson, who reached his career-high rank of No. 58 this month, will have another opportunity in the next round when he goes up against the only unseeded player with a first-round bye, Australia’s Marc Polmans.
Daniil Medvedev, 21, and Reilly Opelka rewarded those who stayed up past their weekday bedtimes with the match of the day. Opelka, 19, pushed Medvedev to his limit before the 50th-ranked Russian closed out the match 6-7(8), 6-3, 7-6 (6). Nicolas Mahut and Lukas Lacko also booked second-round slots.
An all-American matchup capped off late-night action in Washington, D.C. Donald Young took out Tim Smyzcek in three set midnight match.
Tuesday’s schedule promises plenty of firepower. Top seed Simona Halep will open the day when she takes on 2015 champion Sloane Stephens on Stadium Court. Stephens has played just one tournament this summer since being sidelined for nine months with a foot injury.
