American Jack Sock clinched the last qualifying spot for the ATP Tour final beating Serbian qualifier Filip Krajinovic in the Paris Masters final on Sunday.
Sock came from a set down to beat Krajinovic 5-7 6-4 6-1 to become the first American to win the tournament since Andre Agassi in 1999. He is also the first American to win the Masters tournament since Andy Roddick at Miami in 2010.
The victory for the 25 year old is his first Masters 1000 title, moves him into the top 10 for the first time and sees him qualify for his first ever ATP World Tour Final.
Sock, who started the week in 24th position in the Race to ATP final in London, needed to win the title to leapfrog Spain’s Pablo Carreno Busta into eighth place.
Krajinovic, who was a qualifier for the tournament, is ranked 77th in the world and was appearing in his first final of the season. Krajinovic was the first qualifier in a Masters final since Jerzy Janowicz in 2012 also in Paris.
Players that have qualified for the ATP Tour Final which takes place in London from 12-19 November: Rafa Nadal, Roger Federer, Alexander Zverev, Dominic Thiem, Marin Cilic, Gregor Dimitrov, David Goffin and Jack Sock.
