Fresh-faced Josh Berry has done his homework.
His tennis homework, that is.
The youtube.com sensation has extensively studied tennis stars, from the likes of Andy Murray, the now-retired
Andy Roddick, Novak Djokovic and, of course, Rafael Nadal.
His biggest test came when the French racket company Babolat put him with the Spanish tennis legend and had Nadal judge his impersonations.
Nadal, looking slightly sheepish, was a good sport.
You can judge the video yourself.
Berry's Twitter biography @JoshBerry19 pretty much says it all: That guy that impersonates tennis players.
And doesn't have an agent ... yet.
