Men's Tennis: 5 lesser-known but unique records of Roger Federer

#4 Most consecutive weeks as world number 1

Roger Federer after his US Open win in 2004.

Since the ATP rankings were first introduced in 1973, few players have dominated the charts as much as Federer has. Since ascending to the top of the rankings post his win at the Australian Open of 2004, Federer held on to the top ranking for close to four and a half years until August 2008.

His stay at the top lasted a remarkable 237 consecutive weeks. The last time Federer was ranked outside the Top-4 was way back on March 2, 2003. Since then, for almost 16 years, he has been ranked inside the Top-4 - an all-time record among both men and women. This one statistic is enough to quantify his longevity and success in sport. Federer has also been ranked inside the Top-10 for more than 16 years starting from 14th October 2002.
