Jack Sock snatches last ATP Tour finals spot with Paris title
American Jack Sock clinched the last qualifying spot for the ATP Tour finals when he beat Serbian qualifier Filip Krajinovic 5-7 6-4 6-1 in the Paris Masters final on Sunday.
The 16th-seeded Sock, 25, became the first American to win the tournament since Andre Agassi in 1999.
Sock, who started the week in 24th position in the Race to London, needed to win the title to leapfrog Spain's Pablo Carreno Busta into eighth place.
He did just that with a solid performance, wearing down the defence of world number 77 Krajinovic.
"There have been a lot of firsts," Sock said in quotes on the ATP Tour's official website. "It started at the French Open with my first fourth round of a Slam, now I've won my first Masters 1000 in Paris.
"This will be my first time in the top 10 and this will be the first time making the year-end Finals. So there's a lot going on right now emotionally and I can't wait to enjoy it all with my team."
Sock won his first two service games to love but ran into a spot of bother in the sixth game. He served and volleyed to save a break point but a double fault handed Krajinovic a break and a 4-2 lead.
The American broke straight back but a fine forehand earned the Serb a set point and Sock made a mess of another forehand as his opponent, who defended well, took the lead.
Krajinovic, however, lost his focus and a forehand error gave Sock an early break in the second set. The Serb fell 4-1 down and could only break back once, Sock levelling for one-set all.
The momentum had shifted and Sock, who will finish the year as the American number one for the first time, raced through the deciding set to claim his maiden Masters title.
