Ryan Harrison tells ESPN that certain players relish facing Americans at Roland Garros. The United States hasn't produced a male singles champion since Andre Agassi won the title in 1999.

"You go over there, and you certainly have a target on your back a little bit," Harrison said. "The guys love playing Americans on their home surface, you feel like they're fired up to play you. It's something you've got to use, and stay motivated, and just do your best to fight through each match."
