Serena Williams wins Wimbledon, her third major title in 2015 [VIDEO]

Serena Williams wins her 6th Wimbledon title in match against Garbine Muguruza. Williams has now won 4 consecutive Grand Slam titles: the US Open 2014, Australian Open 2015, French Open 2015 and Wimbledon 2015. This is her 2nd ‘Serena Slam’ since winning 4 titles in a row when she was 21.

If Williams wins the US Open 2015 in September, she will become the 1st tennis player to win all 4 majors in a calendar year since Steffi Graf in 1988, and tie Graf in number of titles with 22.
