Williams is within touching distance of becoming the first woman since Steffi Graf in 1988 to win all four major titles in the same year following her sixth Wimbledon triumph.

The 33-year-old American recovered from a slow start to ease to a 6-4, 6-4 victory over Spain's Garbine Muguruza that gave her a 21st Grand Slam crown on Saturday and made her the oldest woman to win a major in the Open era.
