ST. PETERSBURG, Russia — Australian Open finalist Petra Kvitova struggled with her serve and was eliminated from the St. Petersburg Ladies Trophy on Friday after losing to eighth-seeded Donna Vekic 6-4, 6-1 in the quarterfinals.
The second-ranked Kvitova landed only 48 percent of her first serves, double-faulted six times and was broken five times.
Kvitova, the defending St. Petersburg champion who lost to Naomi Osaka in the Australian Open final, was playing in her 14th match in 24 days. It was Vekic’s fifth match in that time.
Vekic will next face either third-seeded Daria Kasatkina or Vera Zvonareva in the semifinals.
Fourth-seeded Aryna Sabalenka reached the semifinals by beating Russian qualifier Ekaterina Alexandrova 6-3, 6-4. She will next play either Kiki Bertens or Anastasia Pavlyuchenkova.
LYON, France (AP) Former champion Jo-Wilfried Tsonga rallied past Canadian qualifier Steven Diez on Wednesday to reach the quarterfinals and extend his perfect record at the Lyon Open.
Tsonga, the 2017 champion, came within two points of losing but finally prevailed 3-6, 7-6 (2), 6-3 on his sixth match point after 2 hours, 42 minutes.
The clay-court event serves as a warmup for the French Open, which starts Sunday in Paris.
“It was good for me to play a long match like this,” Tsonga said. “I haven’t played a match this long for a while. I am not playing my best level, but I am giving everything mentally and that gives me confidence.”
Tsonga will next take on top-seeded Nikoloz Basilashvili, who beat lucky loser Tristan Lamasine 7-5, 7-5.

STRASBOURG, France (AP) Top-seeded Ashleigh Barty withdrew from the Internationaux de Strasbourg clay-court tournament on Tuesday because of a right arm injury.
Barty was replaced in the main draw by lucky loser Diana Marcinkevica.
The eighth-ranked Australian said she would not take any risk ahead of the French Open, which starts Sunday in Paris.
“I gave it my best chance, but unfortunately I wouldn’t be playing my best tennis,” Barty said. “I’m busy the next two months and I need to look after my body now.”
