Andy Murray will be the ATP's world number one for the first time on Monday after reaching the final of the Paris Masters to end Novak Djokovic's lengthy reign at the top of the rankings.
We take a look at the numbers behind the Briton's rise to the summit of the men's game.
76 - Murray has spent a total of 76 weeks as world number two, but will finally move to top spot when the updated rankings are released on Monday.
26 - The newest number one will be the 26th man to claim the honour since the computerised rankings were introduced in 1973.
4 - However, Murray is only the fourth man to do so since February 2004, when Roger Federer began a 237-week streak as the leading player on the ATP Tour. Rafael Nadal and Djokovic are the only men other than Federer to have topped the rankings thereafter.
1 - Australia's Pat Rafter is the owner of the briefest stint as world number one, having spent one week in the position in 1999.
29 - Murray, who turned 29 on May 15th, will become the oldest first-time number one since Australia's John Newcombe topped the rankings in June 1974 at the age of 30.
18 - Victory over Tomas Berdych on Friday represented an 18th consecutive match win for the Briton, who is chasing a fourth title in as many tournaments.
2 - Murray is not the first member of his family to claim a number-one ranking in tennis. His elder brother, Jamie, has enjoyed two brief stints atop the men's doubles rankings in 2016.
122 - Djokovic's reign at the summit will come to an end after 122 consecutive weeks - a streak bettered by only three men in Federer (237 weeks), Jimmy Connors (160) and Murray's coach, Ivan Lendl (157). Djokovic has held the number-one ranking in each week since July 7, 2014.
223 - The Serbian has spent 223 weeks in all as world number one. Federer (302), Pete Sampras (286), Lendl (270) and Connors (268) are the only players ahead of him in that respect.
