The 22-year-old Sinner already had one hand on the No 1 ranking before the clay-court Grand Slam got underway as Djokovic had to reach at least the semi-final to deny the Italian top status.
However, with the 24-time Grand Slam forced to withdraw from his quarter-final clash against Casper Ruud due to a knee injury that required surgery, Sinner’s ascend to the top was confirmed on Wednesday.
Reigning Australian Open champion Sinner will have a handy lead after the tournament, but how big the lead is will depend on the outcome of Sunday’s final.
Following his loss to Carlos Alcaraz in the semi-final, Sinner leads Djokovic by 1,165 in the LIVE Rankings but that lead could be reduced to 745 if the Spaniard wins the French Open.
An Alcaraz victory over Alexader Zverev would see him move ahead of Djokovic in the rankings by the closest of margins as the Spaniard would be on 8,580 points compared to 8,360 points from the Serbian.
The only other change in the top 10 sees Stefanos Tsitsipas slip down two places to No 11 while Alex de Minaur equals his career-high No 9 after reaching the quarter-final.
There are also minimal changes in the rest of the top 20 with Félix Auger-Aliassime climbing three places to No 18 as he made the round of 16.
Jesper de Jong had a storming French Open as he came through qualifying, stunned Jack Draper in five sets in the first round and then took a set off Alcaraz in the second round.
