PRAGUE — Bernarda Pera reached her second WTA Tour semifinal by upsetting third-seeded Qiang Wang 6-0, 6-7 (5), 6-3 at the Prague Open on Thursday.
It was only the American’s second career victory over a top-20 ranked player and earned Pera a meeting with another surprising semifinalist, Karolina Muchova. The Czech player, who was given a wild card for the tournament, eliminated Russia’s Natalia Vikhlyantseva 6-3, 6-4 to advance to her first WTA semifinal.
In an all-Czech quarterfinal, ninth-seeded Barbora Strycova eased past No. 6 Katerina Siniakova 6-1, 6-2, improving her record against her countrywoman to 4-1.
Swiss qualifier Jil Teichmann also reached her first WTA semifinal by knocking out German lucky loser Tamara Korpatsch 6-2, 6-1.
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).
