Um...There is no rule about how many sets they have to play...They play the best out of 5 sets in each round at a Grand Slam event...So the score in one match can be 3-0,3-1 or 3-2...In 1 Grand Slam a male tennis player can play BETWEEN 3 and 21 sets(Depends in which round they have been eliminated,what the score was,or if they won the event...)

Last 4 Grand Slams Men:

Wimbledon 2010:Rafael Nadal defeated Tomas Berdych 6-3 7-5 6-4
