Serena Williams ready for next step to Slam

Serena Williams will look to take another step on the road to a calendar grand slam tonight when she faces Roberta Vinci in the US Open semi-finals tonight.

Williams and her sister Venus added another chapter to what the world No.1 claims to be greatest story in tennis when she outslugged her older sibling 6-2 1-6 6-3 in the early hours of Wednesday morning to reach the semi-finals of the US Open.

There are few that would disagree with Serena that the Williams sisters’ rise from the hard scrabble streets of Compton to the top of the tennis world is both fascinating and inspiring.
