landed just 42 percent of first serves in the first set and made 20 unforced errors, struggling to find the bite and consistency he had enjoyed in beating Federer.In the second set, neither player earned a break point until the sixth game, when Goffin saved himself with a dramatic backhand crosscourt shot that caught the sideline.
With the pendulum suddenly swinging, Goffin took advantage of two double faults from the racquet of Dimitrov, smashing a forehand winner past him to seal the break in the next game.Infused with renewed belief, the Belgian held his nerve to clinch the set 6-4.
Despite a sprinkling of break points, a tight third set went with serve until the sixth game, when Dimitrov earned a break to lead 4-2 as Goffin went wide with a backhand.As the tension mounted, Goffin bravely saved three championship points on his own serve but Dimitrov held his nerve to seal the match on his own serve after two-and-a-half hours at the fifth time of asking.
Dimitrov, 26, has enjoyed the best season of his career, claiming his first Masters title in Cincinnati and winning two other titles as well as reaching the Australian Open semi-finals.
He is guaranteed to finish the season third in the rankings.Nicknamed “Baby Fed” early in his career for the similarity of style in his game to the Swiss, Dimitrov has struggled to live up to the comparison, slipping to 17th in the rankings at the end of the 2016 season.
The final that nobody expected came just a year after Novak Djokovic and Andy Murray battled it out here for the number one slot.
But both players have been absent from the Tour for months and with Nadal also forced to pull out of the ATP Finals after his round-robin opener, the end-of-season finale has had an unusual flavour.Sunday’s final was the first time in the tournament’s history that two players who qualified for the first time faced off in the title decider.The last player to win the trophy in their first year as a qualifier was Alex Corretja in 1998.
