Wimbledon champion Petra Kvitova and French Open winner Maria Sharapova suffered third round shock exits while top seed Serena Williams avoided the upset bug Thursday at the WTA Montreal hard court tournament.
Russian Ekaterina Makarova upended second-seeded left-hander Kvitova 6-4, 1-6, 6-2, while diminutive Spaniard Carla Suarez Navarro stunned fourth-seeded Sharapova 6-2, 4-6, 6-2, following a third-set rain delay, at Uniprix Stadium.
Williams advanced by defeating Lucie Safarova 7-5, 6-4 to reach the quarterfinals.
Suarez Navarro, who is seeded 14th in Montreal and ranked 16th in the world, shrugged off two rain delays at the $2.4 million event and emerged with the victory over Sharapova who saw her preparations for the upcoming US Open suffer a huge setback.
“I couldn’t find my rhythm from the beginning. Always had my back against the wall throughout the whole match,” Sharapova said.
The former world No. 1 Sharapova, who’d won 11 of her previous 12 matches on tour, has now lost her last two three-set matches after winning 11 straight.
Suarez Navarro put on a crisp shot-making display as she cruised through the first set.
Sharapova, who had also started slowly but managed to rally against second-round opponent Garbine Muguruza, battled back from a 4-2 deficit in the second to force the decisive third set, but she had no answer for Suarez Navarro in the third.
“It was a tough match,” Sharapova said. “I thought my opponent played a really good match.
“Even though I felt like I started feeling a little bit better, it wasn’t enough in the end.”
Sharapova’s wayward backhand on match point was her 49th unforced error of the contest. She converted just six of her 19 break point opportunities.
