Roddick goes down on first day of Open

American Andy Roddick has been the biggest name to fall on day one of the French Tennis Open in Paris.

Roddick has lost in four sets to Frenchman Nicolas Mahut, who has only won for the second time in ten attempts in Paris.

It's Roddick's 5th first round loss at Roland Garros and he admits his movement on clay is terrible.

"You can't fake it out here, you know these are the best tournaments in the world, it's tough to lie out here. May footwork on this stuff is really, really bad."

Meanwhile US Open champion Sam Stosur has made a powerful start to the Open.

The 2010 finalist has brushed aside Britain's Elena Baltacha 6-4, 6-love to join former champions Ana Ivanovic and Svetlana Kuznetsova in reaching the second round.

Stosur reflects on her start.

"Yea it was good, obviously very happy with the way I played and the score line and everything else it's definitely a nice one to have underway and through to the second round."

New Zealand's Marina Erakovic gets another day off - she's not on the day two schedule.
