She's #1: with her first Grand Slam title, Amelie Mauresmo becomes the top-ranked woman player in the world.

For the second time in her career, out tennis sensation Amelie Mauresmo has hit the top of her sport. She nabbed the number 1 ranking on March 20 after a stellar few months of WTA Tour play, including her first Grand Slam title at January's Australian Open.

"Getting back to number 1 is a wonderful feeling," Mauresmo, 26, said in a statement. She first held the top ranking for five weeks in 2004. "There have been a lot of memorable moments for me recently, and being number 1 again is another one."

She came out as a teen during the 1999 Australian Open, where she made her first--and until this year only--Grand Slam final. Though she's one of the fittest, most versatile players in women's tennis, Mauresmo has sometimes seen her nerves undermine her in big matches. But her mind and body held up this year. During her Melbourne Grand Slam run, three of her opponents retired in the searing sun, including Belgium's Justine Henin-Hardenne in the final.

"I now have achieved everything I announced in my career: Fed Cup, being number 1, and winning a Grand Slam," Mauresmo said afterward. "I'm very proud, I have to say."
