There are a number of candidates who will be competing long after Venus and Serena Williams hang up their tennis shoes, as evidenced by the number of American women making it past the US Open first round.
Second-seeded Simona Halep needed three sets to win her first-round match at the US Open. Ditto for Angelique Kerber, Venus Williams and Andrea Petkovic. Sometimes the early pressure is the most intense pressure.
If you can't go any bigger than that, Ernests Gulbis, it's time to go home. The Latvian's remarks about professional tennis players and motherhood were insensitive, but not even Maria Sharapova could take them seriously.
Steffi Graf has done it. So hasn't Margaret Court and Maureen Connolly. Serena Williams is primed to join their company as the winner of a true Grand Slam this year, but it all starts with getting past Victoria Azarenka in the Australian Open.
