Maria Sharapova crashed out of Wimbledon today as world number 131 Michelle Larcher de Brito caused a shock in one of the noisiest matches to have been played at the All England Club.

The Russian won the title nine years ago but this time around exited at the second-round juncture after a 6-3 6-4 loss to her unfancied Portuguese opponent.

Until now Larcher de Brito has been best known for her loud high-pitch screech, but today she showed her on-court credentials by outplaying the four-time grand slam champion on Court Two.

Sharapova did not go down quietly, though.

The 26-year-old arguably edged the battle of the shriekers and may well have something to say about the surface after becoming the latest player to be hurt when slipping on the turf.

Caroline Wozniacki was also left spread-eagled as she limped out of Wimbledon following a 6-2 6-2 second-round defeat by Czech Petra Cetkovska.

Wozniacki called for the overworked Wimbledon trainer to attend to her stricken ankle and battled on after applying some spray and strapping to her ankle and foot.

As the right-handed ninth seed struggled to put any pressure on her left ankle as she went through her service motion, another observer described her as a "half-lame Wozniacki".

What was clear was that the Dane wanted the ordeal to be over sooner rather than later and Cetkovska obliged by finishing off the match in 75 minutes.

Petra Kvitova was handed a free pass through to the third round with the withdrawal of Yaroslava Shvedova.

Former champion Kvitova was handed a Court One assignment against Shvedova but the Czech did not need to leave the locker room.

Kazakhstan player Shvedova had an arm injury that ruled her out, with 2011 title winner Kvitova advancing to the last 32.
