With the Australian Open in the books, here’s a look at some of the numbers that defined the tournament.
1: Countries with multiple active men's Grand Slam singles winners. Switzerland has Roger Federer and Stanislas Wawrinka, the only two Swiss men to win majors.
2: Titles this season for Wawrinka, a career high. He won the Chennai Open before the Australian Open.
4: WTA players who have saved match point on their way to the Australian Open title in the Open era. Li Na, who saved a match point in her third-round match against Lucie Safarova, joined Monica Seles, Jennifer Capriati and Serena Williams.
6: Active WTA players with multiple Grand Slam singles titles -- Serena Williams (17), Venus Williams (seven), Maria Sharapova (four) and Victoria Azarenka, Svetlana Kuznetsova and now Li (two apiece).
7: Players who have been the last U.S. man standing at the last seven Grand Slam tournaments.
8: Wawrinka's seed at the Australian Open, where he became the first No. 8 seed to win a Grand Slam title since Brian Teacher at the 1980 Australian Open.
9: First-round retirements (including a record eight on the men's side), matching the record, set at the 2011 U.S. Open, for retirements or walkovers in a single round of a Grand Slam tournament.
12: Consecutive first-round losses at Grand Slam tournaments for Marinko Matosevic, who fell to 0-12 with an opening-round defeat to Kei Nishikori.
13: Years that Federer was Swiss No. 1, a streak that ended when Wawrinka surpassed him after the Australian Open.
14: Consecutive Grand Slam semifinals for Novak Djokovic before his quarterfinal loss to Wawrinka.
15: Consecutive losses for Wawrinka to No. 1 players before he beat top-ranked Rafael Nadal in the final.
16: Consecutive Grand Slam titles for ATP Big Four -- Nadal, Djokovic, Federer and Andy Murray -- before Wawrinka's victory. The Big Four had won 34 off 35 majors, too.
20: Seeding of the highest-seeded player (Dominika Cibulkova) Li faced en route to the title.
21: Years since a men's player had defeated No. 1 and No. 2 to win a Grand Slam title. Sergi Bruguera did it at the 1993 French Open, and Wawrinka joined him in Melbourne.
26: Consecutive sets, over 12 career meetings, that Nadal had won against Wawrinka before the final.
30: Years since a Canadian had reached a Grand Slam semifinal. Carling Bassett-Seguso accomplished the feat at the 1984 U.S. Open, and 19-year-old Eugenie Bouchard ended the drought in Melbourne.
36: Grand Slam starts for Wawrinka, second for most appearances before winning a first title. Goran Ivanisevic won Wimbledon in 2001 in his 48th Slam.
57: Consecutive Grand Slam appearances for Federer, who this year broke the record of 56 he had shared with Wayne Ferreira. The next longest active streak is Feliciano Lopez's 48.
61: Career victories for Serena Williams at the Australian Open, a record she set with her third-round victory.
63: Consecutive matches that Federer had played at the Australian Open's main show court, Rod Laver Arena, before his second-round match at Hisense Arena.[H/T Greg Sharko, Kevin Fischer, ITF]
