“In the first set I did not start very good. I was very nervous coming into the match. I did not know what to expect what to expect. I was not playing good and then I obviously found my rhythm and started to play much better. I started to read his serve a little bit as well and I was very solid on my serve”, said Coric.
Coric set up a semifinal match against Milos Raonic, who beat Karen Khachanov 6-1 7-6 (7-1) in 86 minutes. Raonic got two consecutive breaks to win the first set 6-1.
