Roger Federer replaces Andre Agassi as oldest world No. 1 in history


Roger Federer returned to world No. 1 for the first time since 2012 to become the oldest top-ranked player in history.
The Swiss beat Robin Haase 4-6, 6-1, 6-1 in a tough encounter at the Rotterdam Open quarter-finals to replace Andre Agassi as the oldest man to sit at the top of the ATP rankings.
Federer was stunned as Haase won the first set on Centre Court but the veteran responded in style with three comprehensive set victories against his Dutch opponent.
Agassi sat atop of the ATP leaderboard at 33 years old in 2003 but Federer, 36, has smashed that record.

Federer will replace Rafael Nadal at the top of the ATP rankings on Monday, just weeks after claiming his 20th Grand Slam title at the Australian Open – his first spell at No. 1 since November 2012.



Incredibly, Federer first topped the rankings in February 2004 and he has now set a record for the longest gap between first and last stints in top spot.
The two-time Rotterdam Open winner is unbeaten in 2018 and is two victories away from adding his second ATP title of the year.
