How long can he stay at the top of the rankings? It's going to be tough to knock him off, unless he picks up a bad injury. But Roger Federer has
equalled American great Pete Sampras's mark of 102 weeks as world No.1 in the ATP rankings. There is still 2 above him in the rankings and it will
take some feat to beat Conners on 160 and Lendl on 157, but its not impossible.
