Hingis who had to retire at the age of 22 with a foot injury said on Friday that playing at Pattaya will be a test. “I don't know how my body will react," she told Switzerland's Le Matin newspaper.”

"I was a bit rusty in the beginning with some small pains in my calf at times, but that is part of the game. The state of my preparation is a question of mental preparation above all."

After losing her last official match at the Porsche Tennis Grand Prix in Filderstadt she told the press a few months later that her physical problems wouldn’t let her play again. The injury made it impossible to play tennis longer than the necessary hours of practise she needs to be a top player.

Every time someone asked her about a possible comeback she said she needed a medical miracle to happen to make a comeback. All the time she stayed in touch with her former colleagues on the tour through her work as a TV hostess during various Grand Slams. She said she was missing the competition and joked how she wanted to jump on court and show everyone how tennis should be played instead of sitting in a TV booth.

The Swiss Miss also kept herself in the news through working for her sponsors and charity work. Her trip to Pattaya is part of her charity work as well and takes the trip as an opportunity to play competitive again with a low profile.

"I support several charities in Thailand. I'm also playing to see where I am, at Pattaya there will not be as many people and the players are ranked between 30th and 95th in the world," the Swiss five times Grand Slam Champion said.
