Othe rplayers who have posed nude for ESPN magazine include Serena Williams (June 2009 cover) and John Isner (March 2013). Tennis players Tommy Robredo, Jo-Wilfried Tsonga and Fabio Fognini have also posed nude for various magazines over the years.
Which tennis players would you like to see pose nude? My money would be on Gael Monfils, Feliciano Lopez, Fernando Verdasco or Roger Federer. (In that order!)
