World number one Naomi Osaka and Wimbledon champion Simona Halep battled to three-set triumphs on Wednesday at the ATP and WTA Cincinnati Masters while top seed Ashleigh Barty ousted Maria Sharapova.
Reigning US and Australian Open champion Osaka needed more than two hours to outlast Aliaksandra Sasnovich 7-6 (7/3), 2-6, 6-2.
The Japanese star will next face a third-round match against Taiwan’s Hsieh Su-Wei, who defeated American Jennifer Brady 7-6 (11/9) 6-3.
Osaka finally scored a win here at the US Open warm-up after losing in the first round a year ago. Osaka advanced with eight aces, 24 winners and breaks on four of five chances against an opponent who was treated on her right knee several times.
Australia’s Barty, 23, won the battle of former number one players in just over 90 minutes. The reigning Roland Garros champion beat five-time Grand Slam winner Sharapova, who was Cincinnati champion in 2011, for the second time this season after a win at the Australian Open.
It was Barty’s 40th victory of 2019 and she goes on to face Estonia’s Anett Kontaveit, who beat Polish teenager Iga Swiatek 6-4, 7-6 (7/2).
Barty said she remained focused after last week’s opening defeat in Toronto.
Barty fired 18 winners, breaking Sharapova four times as the Russian made 31 unforced errors.
Fourth-seeded Halep took a late break in the penultimate game of the final set to beat Russian Ekaterina Alexandrova 3-6, 7-5, 6-4 after two hours on court.
The Romanian has finished runner-up in Cincinnati three times, last reaching the final a year ago against Kiki Bertens.
In the next round, the 27-year-old, who retired injured from her Toronto quarter-final against Czech qualifier Marie Bouzkova last week, will face American Madison Keys, a 6-4, 6-1 winner over Russia’s Daria Kasatkina.
World number three Karolina Pliskova beat China’s Wang Yafan 6-1, 6-3, while seventh seed Elina Svitolina, a semi-finalist four years ago, advanced past Belgian Elise Mertens 6-4, 6-1.
In the men’s draw, fifth seed Stefanos Tsitsipas saved three match points but still lost to Germany’s Jan-Lennard Struff 6-4, 6-7 (5/7), 7-6 (8/6).
Kei Nishikori went out to fellow Japanese Yoshihito Nishioka 7-6 (7/2), 6-4. Sixth seed Nishikori has still never advanced beyond the third round in Cincinnati.
