Alex Rodriguez, Roger Federer, Li Na and Saturday’s Sports News

Li Na started playing professional tennis in 1999, but unlike many American tennis phenoms, it took her 10 years to win her first Grand Slam tournament at the French Open.

Since she defeated Kim Clijsters in January in the final of the Sydney International—her first WTA "premier" level title—Na's star has taken off.

Matched up against defending champion Francesca Schiavone, Na dominated, winning in two sets 6-4, 7-6 (0).

Na is the first Chinese player to win a Grand Slam tournament and figures to be a force on the WTA for years to come.  She is currently ranked No. 4 in the world.

Roger Federer has a bit more of a track record than Na.  Tomorrow, he will go for his seventeenth Grand Slam title, against Rafael Nadal.  The two players, regarded by many as the two best in the world, have not matched up with one another in two years.  

Nadal is the favorite because the game is on clay—his wheelhouse—but the way he has been playing recently, the odds might not change on another surface.  Regardless, the final tomorrow will be must-see TV.

“It will be one for the ages,”  Andre Agassi said in The New York Times. “Any time you see these two, Nadal and Federer, go head to head, it’s one of the most memorable moments. And to have it happen in a final — we have been spoiled, we’re so used to watching them.”

Alex Rodriguez and girlfriend Cameron Diaz have also split up, according to The New York Daily News.  His personal struggles haven't been getting in the way of his play though, as Rodriguez is hitting .370 over the last 14 days.

Aaron Gleeman of NBC Sports wrote, "....since breaking up with his wife, the 35-year-old Rodriguez has dated and broken up with Kate Hudson, Madonna, and now Diaz, which is an eclectic mix to say the least. Hudson is 32, Diaz is 38, Madonna is 52, and Madonna’s arms are 107."
