Serena Williams won a dramatic French Open final against Czech 13th seed Lucie Safarova to claim her 20th Grand Slam title. The American, ranked number one, needed two hours and one minute to win 6-3 6-7 (2-7) 6-2 at Roland Garros. Safarova, playing her first Grand Slam final, led by a break in the decider but Williams won the last six games. The 33-year-old becomes the third player – male or female – to win 20 major singles titles. Only Germany’s Steffi Graf on 22 has won more since the open era began in 1968, with Australia’s Margaret Court collecting 24 between 1960 and 1973. Victory at Wimbledon in July would see Williams hold all four major titles at once, having managed the feat already in 2003.
