Serena Williams overcame a slow start, eight double-faults and a nervy finish to beat Garbine Muguruza 6-4, 6-4 on Saturday for her sixth Wimbledon title, fourth Grand Slam championship in a row and 21st major overall.
Williams, winning her 28th straight Grand Slam match, is now just one major title behind Graf on the Open era list and two behind all-time leader Margaret Court.
At 33, Williams is also the oldest woman to win a Grand Slam title in the Open era. She has now won eight major championships in her 30s.
