Canadian Bouchard marched through to the 2014 final, where Petra Kvitova denied her the title, but has endured a terrible season on tour and the Wimbledon exit adds to her troubles.

She lost 7-6 (7/3) 6-4 to China’s Duan Ying-Ying on Court Three, sealing her own fate by cracking a forehand into the net.

Elsewhere in the women’s draw, third-seeded Romanian Simona Halep was also on the wrong end of a shock, losing in the first round 5-7, 6-4, 6-3 to Jana Cepelova of Slovakia.

Halep reached the semi-finals 12 months ago, just a month after finishing runner-up at the French Open.

The 22-year-old Cepelova, ranked 106 in the world, had won only one match on the tour all year before Tuesday.

She goes on to face another Romanian, Monica Niculescu, for a place in the last 32.
