Novak Djokovic leads all men's players with 24 Grand Slam singles titles. On the women's side, Margaret Court holds the all-time record with 24 titles (across amateur and Open eras), while Serena Williams leads the Open Era with 23. Djokovic also holds the record for most weeks at world No. 1 with over 428 weeks.
John Isner defeated Nicolas Mahut at Wimbledon 2010 in a match lasting 11 hours and 5 minutes spread over three days.
