PRAGUE — Anastasia Potapova rallied to beat second-seeded Anastasija Sevastova 2-6, 6-3, 6-2 Tuesday to reach the second round of the Prague Open.
Sevastova’s loss means the tournament is already without its top two players after No. 1-seeded Karolina Pliskova withdrew because of a virus. And in another upset, wild-card entry Svetlana Kuznetsova defeated last year’s finalist, fourth-seeded Mihaela Buzarnescu 6-4, 6-2.
Third-seeded Qiang Wang is still in contention, though, after beating Margarita Gasparyan 6-3, 3-6, 6-2.
In an all-American first round, unseeded Jennifer Brady came from a set down to upset fifth-seeded Danielle Collins 5-7, 6-3, 6-0 while No. 6 Katerina Siniakova eased past Dalila Jakupovic 6-0, 6-2.
Anna Karolina Schmiedlova knocked out seventh-seeded Viktoria Kuzmova 6-3, 6-3 in a Slovak derby. Ninth-seeded Barbora Strycova dispatched 2017 champion Mona Barthel 6-4, 6-2.
Bernarda Pera, Jessica Pegula, Mandy Minella, Jana Cepelova, Tamara Korpatsch, Antonia Lottner, Karolina Muchova, Jil Teichmann and Natalia Vikhlyantseva also all advanced.
WIMBLEDON, England (AP) Roger Federer delivered another vintage Centre Court performance to reach a record-extending 17th Wimbledon quarterfinal.
Federer ousted 17th-seeded Matteo Berrettini 6-1, 6-2, 6-2 in a match that only lasted 1 hour, 14 minutes.
The eight-time Wimbledon champion lost only one point on his serve in the first set and didn’t face a break point until he was up 3-0 in the third. He saved that one and went on to serve out the match at love.
The 37-year-old Federer became the oldest man to reach a Grand Slam quarterfinal since Jimmy Connors did it at 39 at the 1991 U.S. Open.
WIMBLEDON, England (AP) Four-time champion Novak Djokovic is into the Wimbledon quarterfinals again after beating Ugo Humbert in straight sets.
Djokovic took advantage of 34 unforced errors to win 6-3, 6-2, 6-2 on No. 1 Court and set up a meeting with David Goffin.
Djokovic, who beat Kevin Anderson in last year’s final, reached his 11th Wimbledon quarterfinal. That puts him level with Boris Becker in fourth place on the all-time list. Roger Federer was trying to reach a record-extending 17th later.
Goffin beat Fernando Verdasco 7-6 (9), 2-6, 6-3, 6-4.
Sam Querrey also advanced after winning an all-American matchup against Tennys Sandgren 6-4, 6-7 (9), 7-6 (3), 7-6 (5).
