Defending women's champion Vondrousova ousted in 1st round at Wimbledon

Defending champion Marketa Vondrousova was knocked out in the first round of Wimbledon on Tuesday, the first female holder to fall at the opening hurdle since Steffi Graf 30 years ago.

Czech Vondrousova, who became the first unseeded woman to lift the title last year, earned a far less welcome accolade after a 6-4, 6-2 defeat by Spain's Jessica Bouzas Maneiro.

"Yeah, it just didn't go as planned today," a downcast Vondrousova said, adding that despite her best efforts the pressure of defending the title had got to her. "I feel like even if you don't want to think about it, you just think about it ... all the time here, I see posters here and everything, my name everywhere.

"Today I was really nervous since the start. I couldn't shake it off. Also she was playing good. I didn't have many chances to come back into the match or she didn't give me many free points. Yeah, credit to her. I'm going to come back stronger, I hope."

Ranked world No. 83, Bouzas Maneiro had won only one tour-level match all year heading into Wimbledon, but secured her first win across all Grand Slams when she slapped a backhand down the line.

"It is one of the most important moments of my life," the Spaniard smiled as she soaked up the cheers. "I'm just ... I'm surprised with myself to be honest."

Canada's Leylah Fernandez continued her impressive grass-court season with a 6-4, 6-3 win over Italy's Lucia Bronzetti.

Fernandez, seeded 30th in the women's singles draw at the All England Club, had three breaks in the match, including a key win to go up 4-2 in the second set.

The 21-year-old from Laval, Que., won 80 per cent of both first serve points and net points, hit 21 winners to Bronzetti's 10 and
