aingnam, 

I am not so sure what you hve said.  Look at record of margeret court . 62 Grand slams including 24 singles.


Yeah, In men's tennis probably federer is all time greatest along with Rod Laver.  Rod Laver missed five glourious years in tennis because of some sort of ban. Or else his record would have been incredible. But rod laver has an amazing record of winning all four grand slams for two years.
