Twice former champion Rafa Nadal was knocked out in the first round of Wimbledon by 135th-ranked Belgian Steve Darcis on Monday, the Spaniard losing 7-6(4) 7-6(8) 6-4. Defending champion Roger Federer began his bid for a record eighth Wimbledon title with a 69-minute demolition of Victor Hanescu Monday as Victoria Azarenka overcame a horrific fall to also progress. Women's second seed Azarenka, a semi-finalist in 2011 and 2012, moved into second round, beating Portugal's world numbr 106 Maria Joao Koehler 6-1, 6-2. Italian fifth seed Sara Errani became the first major casualty of this year's Wimbledon when she slumped to a 6-3, 6-2 defeat to Puerto Rican teenager Monica Puig.
