The ATP knows how to create a splash in its P.R. campaigns and they did that exact same thing to kick-off the 2011 season. They had Roger Federer play Rafael Nadal literally on a court on top of the Doha Bay (which is located in Qatar which will be hosting the 2022 World Cup).  Below are some pics from the event.  Click on the images to enlarge.
