Roger Federer becomes oldest world No.1 in tennis history

After a 5.5-year break, Roger Federer has once again topped the Association of Tennis Professionals (ATP) rankings.

ATP on Monday publicized its new world rankings.

Accordingly, the 36-year-old won the Rotterdam Open to replace Rafael Nadal, 31, at the top of the standings, and he became the oldest world number one in tennis history.

As a result, he broke American Armenian legend Andre Agassi’s record of oldest world number, at age 33.

The Swiss tennis star will remain world number one at least until this year’s Indian Wells Masters, which will be held from March 5 to 18.
