21: Consecutive victories in the month of January for Victoria Azarenka, who has won two Australian Opens in a row.
13: Grand Slam doubles titles for Bob and Mike Bryan after their victory in Melbourne, breaking a tie with John Newcombe and Tony Roche for the most all time. The brothers have won six Australian Opens, four U.S. Opens, two Wimbledons and one French Open.

9: Games lost by Sharapova in the first five rounds, a record low since the Australian Open went to a 128-player draw in 1988.
5: American women who advanced to the third round -- Serena Williams, Venus Williams, Sloane Stephens, Jamie Hampton and Madison Keys -- the most at the Australian Open since 2005.
0: American men who reached the fourth round, the second year in a row.
35: Consecutive Grand Slam quarterfinals for Roger Federer, who lost to Andy Murray in his 10th straight Australian Open semifinal.
