Djokovic proud of 2015 achievement

Novak Djokovic has revealed his immense pride over reaching the final of all four grand slam finals in 2015, after beating Marin Cilic in the US Open semi-final on Friday.

The world number one advanced to the title match at Flushing Meadows by virtue of a 6-0, 6-1, 6-2 victory over defending champion Cilic, in what constituted the most one-sided semi at a grand slam event.

Djokovic bettered the previous record held by Lleyton Hewitt, who hammered Yevgeny Kafelnikov 6-1, 6-2, 6-1 in a last four match at the 2001 US Open.

The victory means Djokovic has reached the final of all four tennis majors in one season for the first time in his career, having won the titles at the Australian Open and Wimbledon and losing in the French Open final.

"It is a great achievement and I'm very proud of it," Djokovic said after his semi-final victory.

"I owe great gratitude to my family and my team. These are the tournaments you want to be performing your best.

"I haven't been very successful in the finals of the US Open, I have won one and lost four but have been playing some of my best tennis on these courts.

"I can promise I will give my maximum, I cannot predict the result but I will give it my best."

Cilic was a shadow of the player who defeated Tomas Berdych, Roger Federer and Kei Nishikori en route to last year's title during Friday's match, and Djokovic subsequently confirmed that his opponent carried an injury coming into the match.

"If people didn't already know, Marin was carrying an ankle injury for the last couple of matches and he was courageous to come out and finish the match today so applauds to him," Djokovic added.

"It is not easy knowing your opponent is not 100 per cent but I'm came out with good focus and intensity and executed the gameplan."
