Serena Williams of the United States looks on in her Women's quarter final match against Sara Errani of Italy on day eleven of the 2015 French Open at Roland Garros on June 3, 2015 in Paris, France

*As we reported earlier, Serena Williams was playing in the French Open while “sick as a dog.”

Well, she gutted it out and Saturday she was crowned champion after defeating Lucie Safarova 6-3 6-7 (2) 6-2 and in the process, she has now claimed a landmark 20th major.

Amazingly this happened after Williams did the almost unthinkable by blowing a 4-1 advantage in the second set and trailing 2-0 in the third.

But Williams recovered and now only Steffi Graf has won more majors in the Open Era at 22. With Williams still going strong at the age of 33, Graf’s record is under serious threat.

The world No. 1 even has a realistic chance of matching the German in 2015, since she’s claimed five Wimbledon titles and is the three-time defending champion at the U.S. Open.

Of course that would mean Williams winning all four majors in a season, something not accomplished since Graf did it in 1988.

But who’d rule her out?

Not her coach, Patrick Mouratoglou.

“I think it’s the most difficult thing to do in tennis,” Mouratoglou told reporters. “That’s why it doesn’t happen often. But as she won the first two, why not believe it’s possible? And second, with her, everything is possible.

“It’s going to be very difficult, but why not?”

But, by winning in Melbourne and Paris, Serena Williams already became the first player since Jennifer Capriati in 2001 to win the first two grand slams in the same season.

That’s an impressive feat to accomplish inn an of itself, but under the condition she won the French Open today, that only adds to her legend.
