Andy Murray will hold the coveted No. 1 spot for the first time when the ATP rankings are published Monday after advancing to the Paris Masters final without playing a single point.
Murray benefited from Milos Raonic's withdrawal from the tournament — just one hour before the big-serving Canadian was scheduled to take on the 29-year-old Briton in the semifinals on Saturday.
Raonic said he withdrew because of a right leg injury.
Murray only needed to make the final in Paris to take top spot off Novak Djokovic. Murray will hold a five-point lead over Djokovic, who lost in the quarterfinals in Paris.
Murray faces American John Isner in the final.
