Sinner leapfrogs Djokovic to take top spot in ATP world rankings
Sinner reached the semi-finals of the French Open where he was beaten by eventual champion Carlos Alcaraz who climbs to second, nudging 37-year-old Djokovic, who has been No.1 since last September, down to third.
Djokovic holds the record for the number of weeks spent at top spot - his tally of 428 is 118 weeks more than next best Roger Federer.
The German Alexander Zverev, who was runner-up to Alcaraz in Paris, remains in fourth place, ahead of Russian pair Daniil Medvedev and Andrey Rublev.
