Fourth seed Ons Jabeur crashed out of the Miami Open on Friday, losing her opening match to Russian qualifier Varvara Gracheva 6-2, 6-2.
In another surprise, Canadian Bianca Andreescu, the former US Open winner now ranked 31st, overcame seventh seed Maria Sakkari of Greece 5-7, 6-3, 6-4, in a gruelling three-hour, three-minute battle in the early afternoon South Florida sun.
Romania’s Sorana Cirstea upset world number four Caroline Garcia 6-2, 6-3 in a repeat of her Indian Wells win over the Frenchwoman last week.
But world number two Aryna Sabalenka got past American Shelby Rogers 6-4, 6-3, despite being hampered by what appeared to be a groin injury.
Tunisian Jabeur, beaten finalist at Wimbledon and the US Open last year, has been working her way back from injury and on her return earlier this month went out in the third round at Indian Wells.
Jabeur underwent surgery after suffering a knee injury at the Australian Open, and subsequently missed the WTA Tour’s Middle East swing.
She looked well short of her best against the 22-year-old Gracheva and had two medical visits during the one-hour 11-minute match.
The win was the biggest scalp yet for Gracheva, who earlier this month reached her first WTA final, losing in Austin to Ukraine’s Marta Kostyuk.
“The plan was, of course like all matches, to be as stable as possible, to try to make her work as much points as possible, and of course wait for comfortable ones to attack,” Gracheva said after her third career win over a top 10 opponent.
“I’ve just probably caught this wave where I’m stable, where I always have a chance to play my game, be aggressive, cause troubles for the others by the game style. I’ve just got to try to keep rolling on this way,” she added.
Andreescu, the US Open winner in 2019, had eliminated Britain’s Emma Raducanu in the previous round and after losing the first set to Sakkari’s pow-erful stroke play, the Canadian settled into a solid pattern of steady returns, peppered with aggressive winners as she took control of the second set.
She took advantage of some loose play from Sakkari but was unable to convert on two match-points at the end, offering a glimmer of hope to her opponent, but finally grabbed the win when the Greek found the net.
“I felt like I was on my heels a lot of the time during the match, but I made every ball,” said An-dreescu.
“I fought to the end, and I think I played the im-portant points just a little bit better today. But it could have gone either way today,” she added.—APP
