Fed, Nadal race thru'

Seven-time champion Roger Federer and Rafael Nadal, the 2008 and 2010 winner, raced into the Wimbledon second round Tuesday as the tournament sweltered in near record-breaking heat.

Second seeded Federer, bidding to become the first man to win eight Wimbledon titles and take his majors tally to 18, enjoyed a 67-minute 6-1, 6-3, 6-3 win over Damir Dzumhur of Bosnia, the world number 88 he beat at the French Open this year.

Federer will face Sam Querrey of the United States for a place in the last 32.

Nadal, defeated in the second, first and fourth rounds in the last three years, reached the second round with a 6-4, 6-2, 6-4 win over Thomaz Bellucci, his fifth win in five meetings against the 42nd-ranked Brazilian.

Tenth-seeded Nadal, his lowest ranking for a decade, faces Germany's Dustin Brown for a place in the last 32.

Andy Murray defied sweltering temperatures to kick off his bid for a second Wimbledon title with a comfortable 6-4, 7-6 (7/3), 6-4 victory over Kazakhstan's Mikhail Kukushkin.

Defending women's champion Petra Kvitova, the second seed, took just 35 minutes to reach the second round, cruising to a 6-1, 6-0 win over Kiki Bertens, the world number 108 from the Netherlands.

Kvitova, also the 2011 champion, dropped just one point on serve and next meets Kurumi Nara of Japan for a place in the last 32.

"It's great to be back on Centre Court and unbelievable to see all the people clapping," said the Czech, who had been laid low by illness in the week before the tournament.

Kvitova's only dropped point on serve came on a double fault in the final game of the match.

The powerful 25-year-old left-hander would have been relieved to have enjoyed a brief first round outing as temperatures rocketed to around 30 degrees Celsius.

Wednesday is expected to see a Wimbledon record high of around 35 degrees which would require the heat index, where matches are briefly suspended, to be consulted.

Organisers say the heat rule, which allows for a 10-minute break between the second and third sets of women's matches, can be used when temperatures rise above 30.1 degrees Celsius.

Eugenie Bouchard, who reached the Wimbledon final last year, was dumped out in the first round by China's Duan Ying-Ying, the world number 117.

The 7-6 (7/3), 6-4 defeat against the qualifier was 12th seeded Bouchard's 12th loss in her last 14 matches and will see her drop out of the world top 20.

However, the rule which has been adopted by Wimbledon after lobbying from the WTA, does not apply to men even though they have to slug it out over the best of five sets.

The highest-ever temperature recorded at Wimbledon was 34C in 1976.

Nadal, who lives in sun-kissed Mallorca, said he would be happy to see the sun keep shining.

"In Australia it can be much, much worse so it's no comparison but actually it's beautiful," said the Spaniard.

"When you have this weather here in Wimbledon it's probably one of the best places in the world."
