2011 Australian Open
The fourth round witnessed women's tennis history, as the match between Kuznetsova and Schiavone broke records. The match became the longest match, in terms of time for women in a Grand Slam as it lasted for 4 hours, and 44 minutes. At 8–7 in the final set Kutznetsova had three match points, but the Italian saved all three. In the next game Schiavone broke her opponents serve but touched the net after hitting the winner, meaning the point went to Kutznetsova, when holding three break points. Kutznetsova had another three match points in the next game before a run of four games in a row where the serve was broken. Finally after breaking in the previous game and missing three match points Schiavone closed the match out to win 16–14 in the final set. Other fourth round matches saw Sevastova's run end against Wozniacki and Makarova's end against Clijsters, while Petkovic upset Sharapova in straight sets. Other upsets saw the seeded players of Li and Kvitová defeat higher seeded players.
