The match was a very important one and despite Cilic playing very well, Djokovic was not to be denied. The Serbian applied early pressure on Cilic but the Croatian was able to hang on and win his opening service game. After that Cilic started playing much better finding very good serves at times when he needed them the most.
He applied a bit of pressure on Djokovic as well but the Serbian remained calm. Cilic played very aggressive tennis as he needed to but Djokovic was simply superb in covering the court and there was very little to work with. At 4-4 Cilic had a 40-0 advantage in the game but complicated things quite a bit by losing three consecutive points.
Djokovic eventually created a break opportunity and converted it to take a 5-4 lead. Cilic jumped out to a 40-15 lead on Djokovic's serve but once again the Serbian was superb. He held on to save 4 break points in total to win the opening set with 6-4. After that everything was a bit easier as Cilic lost confidence and his play eroded quickly. Djokovic went in for the kill taking a double break lead 5-1.
After that, he closed it out with 6-2 for a rather easy victory that did consume quite a bit of energy. Djokovic became angry a few times after long rallies that he failed to win. He will need energy for the doubles match against one of the best doubles pairings in the world Mektic and Pavic.
