Former world number three Coria quits

Argentina's former world number three Guillermo Coria has quit tennis at the age of 27 because he has lost motivation.

"I didn't have any more desire to compete," the former French Open finalist told Radio Continental.

"I had been thinking about it for several months and in Thailand I realised that it was a struggle for me to travel."

Coria, who won nine singles titles and was runner-up at Roland Garros in 2004, last played at an ATP Challenger tournament in Bangkok in March. He has slipped to 672 in the world rankings.

"I'm happy with the decision I've taken because I have some new projects and more time to dedicate to my family," he said.

"In 2005, I didn't feel like competing. In the last three years, things have not worked out the way I wanted and I haven't had so much passion for what I do.

"In this sport, you always have to be 100 per cent."

Coria was a dominant force on clay, winning the Monte Carlo Masters in 2004 before losing in an epic five-setter the following year to Rafael Nadal.

Coria lost the 2004 Roland Garros final to fellow Argentine Gaston Gaudio having held two match points and having lost just one set on his way to the final.

He also served a seven-month ban after testing positive for nandrolone in 2001.
