Maria Sharapova, third-ranked women's tennis player in the world, has just completed one of the most chaotic weeks in her life. She just suffered a shocking defeat in the second round at Wimbledon Wednesday right after her recent controversy with Serena Williams over their dating the same man, a men's professional tennis player. 

He third-seeded Sharapova, who won the tournament in 2004, was beaten by Portuguese qualifier Michelle Larcher De Brito 6-3 6-4, 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 wouldn'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 don't think I was aggressive enough. I just wasn't there."

When asked about the slippery nature of the court and her comment about the surface being dangerous, she added: "I don'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 man who knows Murray

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.
