19 Grand Slams And Still Counting.

Serena Williams won her 19th Grand Slam title, continued her unbeaten run in six Australian Open finals and extended her decade-long domination of Maria Sharapova with a 6-3, 7-6 (5) victory despite a hacking cough on Saturday night.

After celebrating prematurely on her third match point, letting her racket go before hearing a let call to what she thought was an ace, Williams had to quickly re-gather her composure.

"I thought, `Wow this is it, I did it, only to hear let. I was like, `OK Serena!" she said. "I was very disappointed, because Maria was playing so well. I thought she's going to try to hit a winner now. She's goes for broke on match point."
