INDIAN WELLS, United States — World number one Naomi Osaka crashed out of Indian Wells on Tuesday, routed by Belinda Bencic on a day that saw second-ranked Simona Halep sent packing, too.
Bencic, ranked 23rd in the world, defeated Osaka 6-3, 6-1 to reach the quarter-finals of the prestigious WTA premier mandatory event, where Osaka won her first tour title last year.
That marked the start of a remarkable rise that included Osaka’s first Grand Slam title at the US Open. She followed that with an Australian Open crown that sent her to number one.
But she never found her feet against Bencic, whose crisp groundstrokes and precise service game propelled her to victory in 66 minutes.
Bencic, who turned 22 on Sunday, is back on the rise after a string of injuries stalled a career that had exploded with two precocious WTA titles in 2015.
Bencic, who beat four top-10 players on the way to the title in Dubai last month -- her first trophy in four years, next faces fifth-seeded Czech Karolina Pliskova, who downed Anett Kontaveit 7-6 (10/8), 4-6, 6-2.
Osaka’s defeat capped a black day for top seeds in the combined WTA-ATP Masters event, with men’s world number one Novak Djokovic stunned by 39th-ranked Philipp Kohlschreiber.
Roger Federer extended his dominance of Stan Wawrinka on Tuesday, beating his friend and fellow Swiss 6-3, 6-4 to reach the fourth round.
Federer needed barely an hour to take his record to 22-3 over Wawrinka, a former world number three who is currently ranked 40th in the world and working his way back in the wake of double knee surgery.
Fourth-seeded Federer, seeking a record sixth Indian Wells title, next faces Britain’s Kyle Edmund, a 6-3, 6-3 winner over Macedonian qualifier Radu Albot.
The women’s field lost its top two seeds as Romania’s Halep, the 2015 Indian Wells winner, fell to Czech teenager Marketa Vondrousova 6-2, 3-6, 6-2.
Osaka stays No. 1
Halep, who received treatment for blisters on her foot during the match, hit just six winners and piled up 36 unforced errors.
"I was running too much and too defensive," she said. "But it’s everything I could do today."
Her defeat means Osaka will retain her number one ranking, even though she couldn’t pull off her first title defense.
Vondrousova, who beat 2018 runner-up Daria Kasatkina and former French Open winner Jelena Ostapenko on the way to the fourth round, will go for another big win when she faces sixth-seeded Elina Svitolina, who battled to a 7-6 (10/8), 5-7, 6-4 victory over Australian Ashleigh Barty.
Former world number ones Venus Williams and Garbine Muguruza made it into the quarter-finals.
Spain’s Muguruza, a two-time Grand Slam champion now ranked 20th in the world, out-lasted seventh-ranked Kiki Bertens 5-7, 6-1, 6-4 while Williams, a seven-time Grand Slam winner, beat Germany’s Mona Barthel 6-4, 6-4.
Muguruza next faces 18-year-old Canadian Bianca Andreescu, who surprised China’s 18th-seeded Wang Qiang 7-5, 6-2.
Andreescu, who roared to her first WTA final as a qualifier in Auckland in January -- beating two former world number ones on the way -- is in the quarter-finals of one of the WTA’s elite premier mandatory events for the first time.
Andreescu improved her match record for 2019 to 25-3, including qualifying as she became the youngest player to make the last eight at Indian Wells since a 17-year-old Anastasia Pavlyuchenkova reached the semis in 2009.
Williams will fight for a semi-final berth against either eighth-seeded Angelique Kerber of Germany or ninth-seeded Aryna Sabalenka of Belarus. — AFP
