Venus advances in Miami
Azarenka looks sharp in win over Radwanska
Venus Williams upended defending champion Johanna Konta 5-7, 6-1, 6-2 on Monday to reach the Miami Open quarterfinals while a dominant Victoria Azarenka also advanced with a straightforward win over Agnieszka Radwanska.
Three-time champion Williams stormed back from an early deficit to cruise past the British 11th seed, who needed several bouts of treatment on her lower back throughout a match that lasted two hours and 19 minutes.
Perhaps more impressive was that Williams, who turns 38 in June, was able to look so in control despite playing a day after spending nearly three hours on the court for her thirdround clash against Dutchwoman Kiki Bertens.
“The first set was definitely all her, and she came up with some amazing shots to break me at 5-all,” Williams told reporters.
“There was not much I could do there, except hope I could keep up in the second and third sets.”
Former world No.1 Azarenka, in only her second event after an eightmonth absence because of a custody dispute involving her son, also looked sharp throughout her 6-2, 6-2 win over 30th-seeded Pole Radwanska.
The Belarussian, competing as a wild card, won 79 percent of her first service points and needed only 82 minutes to prevail in a clash between former Miami champions.
Up next for the 28-year-old is Czech fifth seed Karolina Pliskova, who advanced to the last eight after Zarina Diyas of Kazakhstan was forced to retire injured while trailing 6-2, 2-1.
“[Pliskova] is an amazing player, a top-10 player,” Azarenka said.
“For me, it’s a challenge to see how I can approach that and how I can progress from that match. It’s perfect. I wouldn’t ask for anything else.”
Former world No.1 Pliskova was efficient from the start and did not drop a point on her first serves in the entire match against Diyas, who took multiple medical timeouts and was visibly struggling with her movement.
Sloane Stephens raised her game to levels similar to last year when she won the US Open as she beat Spanish third seed Garbine Muguruza 6-3, 6-4 and secure passage to the quarterfinals.
The American 13th seed dictated play against the Wimbledon champion from the start by taking eight of the first nine points of the match.
After securing a break in the fifth game of the second set, Stephens sent Muguruza packing with a backhand on the line on her second match point.
Stephens, who equaled her best result in Miami having also reached the quarterfinals in 2015, will next face German 10th seed Angelique Kerber, a 6-7 (1/7), 7-6 (7/5), 6-3 winner over Chinese qualifier Wang Yafan.
Ukrainian fourth seed Elina Svitolina also advanced with a 7-5, 6-4 win over Australian Ashleigh Barty.
French Open champion Jelena Ostapenko capped the night session with a 7-6 (7/4), 6-3 triumph over ninth-seeded Czech Petra Kvitova.
Monica Puig, the 2016 Olympic gold medalist who defeated world No.2 Caroline Wozniacki, had her run ended with a 3-6, 6-4, 6-2 loss to Danielle Collins, who will meet Williams in the quarterfinals.
