Federer, Nadal cruise as Halep, Bouchard crash out at Wimbledon

Seven-time champion Roger Federer and Rafael Nadal both sailed into the Wimbledon second round on Tuesday but women's third seed Simona Halep and last year's runner-up Eugenie Bouchard suffered shocking defeats.

Federer took only one hour and seven minutes to beat Bosnia's Damir Dzumhur. The 33-year-old, bidding to win his eighth Wimbledon title, struck 26 winners to just 12 unforced errors against the world No. 88 for the 6-1, 6-3, 6-3 victory.

The 23-year-old Dzumhur became the first Bosnian man to play a Grand Slam event when he reached the Australian Open third round as a qualifier last year but found it hard to challenge the 17-time Grand Slam winner.

"I was happy I played aggressive," said the Swiss. "He hung around, changed up his game a little bit which also made it a bit more difficult. I'm always happy to win."

Nadal spent more time on No. 1 Court, taking two hours 11 minutes to beat Brazilian Thomaz Bellucci 6-4, 6-2, 6-4.

Nadal, who has slipped to 10th in the world rankings, will next play Dutch German qualifier Dustin Brown, who defeated Lu Yen-Hsun of Chinese Taipei.

The 29-year-old, who lost in the fourth round to teenager Nick Kyrigos last year, was happy with his performance after the match.

"It was a very positive victory," he said. "Straight sets, no bad feelings, good backhands. The forehand needs to be a bit more aggressive." Local hero Andy Murray was also safely into the second round thanks to his 6-4, 7-6 (3), 6-4 win over Mikhail Kukushkin of Kazakhstan.

Bouchard, ranked 12th in the world, was beaten 7-6 (3), 6-4 defeat by unheralded Chinese player Duan Yingying, who until Tuesday had never beaten a player ranked inside the top 50.

It was Bouchard's 12th loss in her past 14 matches and a result that will send her tumbling outside the world's top 20.

But it was third seed Simona Halep who became the biggest casualty. The Romanian was shocked by Jana Cepelova of Slovakia, ranked 103 places lower 5-7, 6-4, 6-3 in a see-sawing match.

"I think emotion. I wasn't there," Halep conceded. "I couldn't handle it very well. She came back in a good way with her game. She was pushing me a lot. She was aggressive. But I can say that I let her come in and play aggressive."

Women's fifth seed Caroline Wozniacki of Denmark claimed 12 of the last 13 games to claim a 7-5, 6-0 victory over China's Zheng Saisai.

The former world No. 1 was down a double break of serve before staging her impressive comeback.

"I started off a little bit nervous, I got broken. Then it was hard to break back. You couldn't really see well from one side," the 24-year-old said.

"But I managed to just keep my head cool and started to play a little bit better and more consistently. That's really it. The second set I had total control and played the way I wanted to play."

Women's defending champion Petra Kvitova eased her way into second round by beating world No.108 Kiki Bertens.

The second-seeded Cezch needed only 35 minutes for the 6-1, 6-0 win over the Dutchwoman on Centre Court.

Kvitova, also the 2011 winner, captured her second Wimbledon title by defeating Dutchwoman Kiki Bertens.

"It was a great feeling," Kvitova said after the match. "I have so many nice memories. I was very nervous. But when I was on the court and people were clapping the atmosphere was unbelievable. " Enditem
