NEW YORK, Sept 8, 2018 (News Wires) - Novak Djokovic will face Juan Martin del Potro for the US Open title after the Serb beat Kei Nishikori 6-3 6-4 6-2 in their semi-final. Djokovic, this year's Wimbledon champion, kept Nishikori under relentless pressure, carving out 17 break point opportunities and winning 80 per cent of his own first serve points to win in two hours and 23 minutes. Twice champion Djokovic, who reached his eighth final at Flushing Meadows and is seeded sixth this year, broke Nishikori in his first service game and closed out the opening set with an ace in 37 minutes without facing a break point. "It felt really good," Djokovic said courtside. "Easier said than done — you have to execute the shots against Kei Nishikori, who is one of the quicker movers on the tour."
