From green and pleasant land, Wimbledon's grasscourts must now resemble a minefield for Rafa Nadal who, for the second year in succession on Monday, suffered a shock defeat by a modest opponent playing the match of huis life. A year after Czech Lukas Rosol ambushed the 12-times grand slam champion in the second round, Nadal came up against inspired Belgian Steve Darcis in the first and was soundly beaten 7-6(4) 7-6(8) 6-4. At least against Rosol twice former champion Nadal went down fighting in five sets, but world No. 135 Darcis subdued arguably the sport's most ferocious competitor in routine fashion. The 29-year-old from Liege, nicknamed The Shark, nailed an ace to send Nadal heading home to Mallorca with a first grand slam opening round defeat against his name. Defeat for fifth seed Nadal was a blow for the tournament but a huge fillip for defending champion Roger Federer whose chances of an eighth Wimbledon title had receded when drawn in the same quarter of the draw as the Spaniard. Federer, opening proceedings on Centre Court for the eighth time in his glittering career, had not lost in the first round of a major since the 2003 French Open, and was never in any danger as he thumped Romania's Victor Hanescu in 68 minutes. The 31-year-old Swiss thoroughbred, rated as a pre-tournament 9-1 title shot by several bookmakers, produced a display of brutal beauty to win 6-3 6-2 6-0. Nadal's subsequent defeat then saw the odds on an eighth Federer title here slashed in half. British hopes of a first men's winner here since 1936 also soared on the back of Nadal's exit as second seed Andy Murray posted a 6-4 6-3 6-2 victory against Germany's Benjamin Becker. It was a bad day all round for fifth seeds with Italy's Sara Errani falling in straight sets to Puerto Rico's Monica Puig. Women's second seed Victoria Azarenka survived a major fright when she fell awkwardly and needed lengthy treatment on her right knee before hobbling to 6-1 6-2 victory over Portugal's Maria Joao Koehler. Third seed Maria Sharapova, let her tennis do the talking as she put aside a verbal spat with world number one Serena Williams to beat Frenchwoman Kristina Mladenovic 7-6(5) 6-3. For the second year running Nadal's defeat left a huge hole in the men's draw and raised inevitable questions about the state of the 27-year-old's knees. After defeat by Rosol last year he was sidelined for seven months before returning in February this year.
