Canada's Eugenie Bouchard and Romania's Simona Halep were the two major casualties on the second day of Wimbledon as the two seeded players were surprisingly dumped out in the first round at the All England Club.

Bouchard has struggled for form following a breakthrough year in 2014, in which she rose to a career high fifth in the world rankings having finished as the runner-up at last year's Wimbledon to the Czech Republic's Petra Kvitova.

She was unable to replicate that level of performance today, bowing out to Chinese qualifier Ying-Ying Duan.

The Canadian began the contest brightly by claiming securing an early break of serve, but she was unable to consolidate her advantage, before losing the first set on a tie break to the 25-year-old Duan.

Duan then consigned Bouchard to her 12th defeat in her last 14 matches, claiming the second set 6-4.

The Canadian number 12 seed claimed after her early exit that she had been suffering from an abdominal injury.

Halep, another rising young star of the women's game, was also a surprise first round exit as her serve was broken on eight occasions by Slovakia's Jana Cepelova who went on to beat the number three seed 5-7, 6-4, 6-3.

There was no such problems for Kvitova, the defending champion, as she powered to a comfortable straight sets 6-1, 6-0 victory on Centre Court against The Netherlands' Kiki Bertens, an encounter which lasted just 35 minutes.

The men's top seeds enjoyed a stress-free opening to their Wimbledon campaigns.

Second seed Roger Federer of Switzerland began his pursuit of an eighth title with a 6-1, 6-3, 6-4 demolition of Bosnia and Herzegovina's Damir Dzumhur on his debut at the tournament.

Although he has slipped to tenth in the world rankings, Spain's Rafael Nadal showed promising early form in his tie against Brazil's Thomaz Bellucci as he moved in the second round with a 6-4, 6-2, 6-4 victory.

The two-time champion will be looking to improve on recent poor performances at the tournament which have seen him fail to make the quarter-finals for the past three editions.

Britain's Andy Murray, the 2013 Wimbledon champion, also came through his first round match unscathed, beating Kazakhstan's Mikhail Kukushkin 6-4, 7-6, 6-4.

Both France's Jo-Wilfried Tsonga and the Czech Republic Tomas Berydch were both forced to win in five sets to secure their progression.

The men's world number one Novak Djokovic of Serbia is due to be the first on Centre Court tomorrow when he faces Finland's Jarkko Nieminen, who is due to retire at the end of the season, before the America's Serena Williams takes to the court in the afternoon where she is set to face Hungary's Timea Babos.
