During every press conference, it's that big white elephant in the back of the room: Will Serena Williams win the 'Golden Slam' at the US Open? 

Patrick and Serena are under a lot of pressure as they continue their US Open preparation in Cincinatti this week.

After losing in the semi-finals last week in Montreal to rising star Belinda Bencic from Switzerland, Serena is determined to win the Cincinatti Open to be fit for the US Open, where she could make tennis history if ever she wins the 'Golden Slam' (winning 4 Grand Slams in the same year).

If there's one player who can do it, it's Serena, and what an achievement it would be to win the 'Golden Slam' on her home turf. 

Serena plays Ana Ivanovic next in the quarter finals, after crushing Italian player Karin Knapp (6/0 6/2) yesterday. We wish Serena and Patrick the best of luck for the rest of the US Open Series and of course for the US Open, where we hope they come back with the trophy.
