( CNN ) -- Maria Sharapova suffered a shock defeat in the second round at Wimbledon Wednesday after being beaten by Portuguese qualifier Michelle Larcher De Brito . Third seed Sharapova , who won the tournament in 2004 , was brushed aside 6-3 6-4 by a player ranked 131 in the world . The Russian appeared to be unhappy with the conditions of the grass court and fell during the second set and appeared to tell the umpire that `` this court is dangerous . '' But after receiving treatment for her fall , she was unable to stave off one of the biggest Wimbledon upsets in recent years . `` I just tried to stay calm , '' Larcher De Brito told the BBC . `` I was playing so well I thought I could keep it up and I just hung in there . She 's a fighter , she just would n't give up for anything . `` There 's lot of grass that 's been cut and not been swept up so there 's a lot of dead grass so it 's not been easy . It 's a tough court to play on . '' Sharapova slipped and fell on Court Two on a couple of occasions and needed a time out to receive treatment to her left hip after the eighth game of the second set . `` It was a combination of everything , '' World No . 3 Sharapova told the BBC . `` I give her a lot of credit , she played extremely well today , really solid from the baseline , I do n't think I was aggressive enough . I just was n't there . '' When asked about the slippery nature of the court and her comment about the surface being dangerous , she added : `` I do n't think I 've ever fallen three times in a match before in my career , so that was a little strange . `` Well , after I buckled my knee three times , that 's obviously my first reaction . '' Sharapova also believes that players should be entitled to practice on the main courts in order to prepare for the tournament . She added : `` The first few days , you just know that they 're going to just be really different . '' The victory is De Brito 's greatest yet with this win representing the first time she has beaten a player ranked inside the top five . The 20-year-old , who will play Karin Knapp of Italy for a place in the last 16 , has never progressed past the third round of a grand slam . De Brito courted controversy in 2009 when she was criticized for her fierce shrieking and her form suffered as a result following mocking by fans . But encouraged by her father , Antonio , who also doubles up as her De Brito 's coach , she bounced back with the love and help of her family . `` If you lose enough times , you think , What am I doing ? That 's where my family stepped in and helped me get pumped up , '' she said . `` I 've been working extra hard in these practices , giving 120 % in practices . My dad really pushed me a lot . `` When I was 16 I was in the top 100 and everybody was comparing me to Martina Hingis , expecting me to win a Grand Slam at that age . `` But that does n't happen anymore , winning Grand Slams so young . Tennis is so competitive now and so hard , it 's hard to stay there . `` I ca n't say enough good things about my father because he helped me a lot . It 's easy to lose motivation . But with these wins , it 's definitely going to help . '' Elsewhere , ninth seed Caroline Wozniacki crashed out following a 6-2 6-2 defeat by Czech Petra Cetkovska , while former World No.1 Ana Ivanovic was beaten by 2012 junior champion Eugenie Bouchard . The Canadian prevailed 6-3 6-3 on Centre Court and will play Spain 's Carla Suarez Navarro in the next round . Monica Puig is through to the third round where she will play Czech Eva Birnerova . Puig , 19 , built on her first round win over fifth seed Sara Errani by defeating Silvia Soler-Espinosa of Spain 6-2 5-7 6-4 . U.S star Sloane Stephens defeated Andrea Petkovic of Germany in three sets , winning 8-6 in the decider .
