Jack Sock's dream ends. The American lost to Grigor Dimitrov, 4-6 6-0 6-3 in two hours, failing to reach his second consecutive final after winning Paris title. It was a very close match, which was predictable as Sock saved one match point to beat Dimitrov in 2015 Montreal, and four match points earlier this year in Indian Wells.
And today it was a battle too. Dimitrov had a great start to the match. In the second game of the first set Sock made two forehand errors and a double fault, Dimitrov was smart enough to play an aggressive tennis and break Sock at 30.
Down 0-3, Jack saved a crucial break point hitting a fast forehand, then he started to be more consistent and solid and broke back his opponent. The American played a creative tennis, Dimitrov was more and more tense, and on 4-all the Bulgarian was broken again.
He hit 17 unforced errors in the first set, most of them since the second half of the set. In the second set the dynamic changed again, with Dimitrov taking risks and playing efficiently. Grigor won 24 points and lost just nine, while Sock dropped mentally.
The third set was the best and most balanced one, with both players extremely raising their level. Sock wasted a break point in the first game, while on 4-3 it was the American to struggle on serve: he didn't convert two game points, made two double faults, and although he saved a break point hitting an unbelievable forehand winner down the line, Dimitrov managed to break him.
On 5-3 the Haskovo native wasted three match points, saved two break points and finally closed the match, becoming the first debutant to advance to ATP Finals Championship since David Ferrer in 2007.
Dimitrov won his 13rd decisive sets match out of 25 played this year, while Sock lost his 10th out of 28. Sock was bidding to become the first American ATP Finals finalist since James Blake in 2006. With this result, he still achieves a new career-high at No.
8, which was something unthinkable a few weeks ago. Dimitrov reaches his fifth 2017 final, he won three (Brisbane, Sofia, Cincinnati) and lost one (Stockholm). Grigor achieved a new career-high ranking at No. 3, overcoming Thiem, Cilic and Zverev in just one week.
Tomorrow he has the chance to end the tournament winning 1,500 points and $2.5 million prize money as undefeated champion. He will face David Goffin for the second time this week, after that in the Round Robin the Bulgarian trashed him prevailing 6-0 6-2.
Of course now it's a different stage and Goffin is much more confident after beating Federer, but Dimitrov seems to be slightly favourite. ALSO READ: Roger Federer: 'I never felt my game 100 per cent, it made me frustrated' .
