Jannik Sinner became Italy's first men's tennis world number one after Novak Djokovic's injury-enforced withdrawal from the French Open on Tuesday. The Australian Open champion was on court playing his quarter-final against Grigor Dimitrov when Djokovic's withdrawal was announced, meaning Sinner will replace the 24-time Grand Slam champion at the top of the rankings next week.

"Due to a torn medial meniscus in his right knee (discovered during an MRI scan performed today), Novak Djokovic... has been forced to withdraw from the Roland Garros tournament," organisers said in a statement.
