Sloane Stephens earned her biggest victory since winning last year’s U.S. Open by beating No. 3-ranked Garbine Muguruza on Monday to reach the quarterfinals at the Miami Open.
KEY BISCAYNE, Fla.—Sloane Stephens’ loudest fan kept shouting advice and encouragement from the upper deck Monday, perhaps providing the nudge she needed to shake a postU.S. Open slump. Stephens earned her biggest victory since winning last year’s Open, beating No. 3-ranked Garbine Muguruza 6-3, 6-4 Monday to reach the quarterfinals at the Miami Open. “Keep it in the court, girl—that’s all you’ve got to do!” the spectator hollered, and Stephens did. During a postmatch on-court interview, Stephens thanked the fan, who has attended her past two matches. “I have no idea who that is,” she said later. “Day before yesterday was the first time I’d ever seen him. But it’s entertaining. Obviously he knows tennis—he was shouting all the right things.” The fan might have picked a good time to jump on the Stephens bandwagon. She’ll next face Angelique Kerber with a shot at reaching the Miami Open semifinals for the first time. Also advancing was three-time champion Venus Williams, who came from behind for the second day in a row and beat defending champion Johanna Konta was 5-7, 6-1, 6-2. The victory Williams’ 64th on Key Biscayne. “I’m not bad at playing tennis,” the 37-year-old Williams said, “so why not keep going?” Victoria threetime Azarenka, another champ champion, swept 2012 Agnieszka Radwanska 6-2, 6-2. Stephens claimed her first major title in New York in September and is ranked 12th, but she arrived at Key Biscayne with a record of only 3-4 this year. “After winning a Grand Slam, it’s not easy to come back right out and keep playing,” Stephens said. “I was so excited after winning the U.S. Open, I was living my life to the fullest. Now I’m back to my day job. It’s a little bit difficult. It takes a little bit of confidence and a lot of hard work.” On the men’s side, qualifier Thanasi Kokkinakis lost in the follow-up to his upset of Roger Federer in the second round. Fernando Verdasco rallied from two mini-breaks down in the decisive tiebreaker and beat Kokkinakis 3-6, 6-4, 7-6 (4). Kerber advanced by rallying past qualifier Yafan Wang 6-7 (1), 7-6 (5), 6-3. Stephens won with typically dogged defense, and by attacking Muguruza’s weak second serve. The Spaniard has been battling a slump herself, falling to 8-6 in 2018. “I missed too many shots, a couple of mistakes I shouldn’t have done in important moments,” said Muguruza, the 2017 Wimbledon champion. “My serve in general could be better. It was not a big difference, but in the end a few details went to her side.” Stephens started the year by losing her opening match in consecutive tournaments, including the Australian Open. She then spent more than a month away from the tour, but said she was no longer celebrating her U.S. Open title.
