ISTANBUL (AA) - Serbian tennis star Novak Djokovic broke Swiss Roger Federer's record for the most weeks as the world’s number one tennis player, according to the Association of Tennis Professionals Tour.
"Djokovic, who captured his ninth Australian Open trophy and 18th Grand Slam title last month, also holds a record 36 ATP Masters 1000 trophies and first attained the No. 1 ranking on 4 July 2011," ATP Tour said in a statement on Monday.
"He has since held the top spot in the rankings across five different stints for a record 311 weeks, one week longer than Roger Federer, who broke Pete Sampras’ record of 286 weeks at No. 1 on 16 July 2012," it added.
Djokovic, 33, has clinched 18 Grand Slam men's singles titles, including nine Australian Open and five Wimbledon championships.
