TIANJIN, China — Top-seeded Karolina Pliskova needed six match points to beat Varvara Lepchenko 6-2, 6-7 (3), 6-3 and advance to the second round of the Tianjin Open on Monday.
Pliskova will next face Polona Hercog, who defeated Lara Arruabarrena 7-6 (5), 6-2.
Also, Russian qualifier Veronika Kudermetova beat 2014 champion Alison Riske 5-7, 6-1, 7-5, fifth-seeded Hsieh Su-Wei beat Ajla Tomljanovic 7-6 (4), 7-5, and Magda Linette defeated Evgeniya Rodina 2-6, 6-1, 6-4.
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).
