PARIS (AP) Serena Williams says it would be ``really intense and really crazy'' if she manages to win the French Open a second time - 10 years after her only title at the clay-court Grand Slam tournament.

Speaking after Friday's draw, which puts her in line for a quarterfinal against Maria Sharapova, Williams says the back problem that bothered her last week in Rome is ``a lot better.''

The 13-time major champion adds that she feels ``really 100 percent'' committed to tennis since returning last year following a series of health scares.

She's also thrilled to have her older sister Venus competing in Paris, too, after being diagnosed with an autoimmune disease. Says Serena: ``Everything that she's doing is so inspiring for me.''
