On Sept. 2, 2011, Samantha Stosur and Nadia Petrova played the longest recorded women's singles match at the US Open since the advent of the tiebreak in 1970, battling for three hours and 16 minutes before Stosur secured a 7-6, 6-7, 7-5 victory.
The third-round win was part of an eventful Open for Stosur. In the next round, the Australian would drop a second-set tiebreak to Maria Kirilenko, 17-15, in what was, at the time, the longest tiebreak in a women's singles match in Grand Slam history. (It has since been surpassed by Denise Allertova's 19-17 first-set tiebreak victory over Johanna Konta at the 2015 French Open.) Stosur would recover to post a 6-2, 6-7, 6-3 victory.
The ninth seed followed that with an upset of No. 2 Vera Zvonareva, a semifinal victory over Angelique Kerber and a title-match shocker over Serena Williams to claim her first and, to date, only Grand Slam singles crown.
