With Williams on 13,161 points and second-ranked Maria Sharapova on 6,490, records dating to the WTA's 1973 founding show Serena's domination to be the greatest in the rankings' history.

The 33-year old American defeated Sharapova in the Wimbledon semi-finals and downed Garbine Muguruza of Spain in Saturday's final to win her sixth Wimbledon title and 21st Grand Slam crown overall.
