Stefanos Tsitsipas will not want reminding, but the match isn’t over until it’s over, after Borna Coric stunned the Greek No.4 seed with a stunning comeback in New York overnight.

Coric, seeded 27, saved six match points, including three in a row with Tsitsipas serving at 5-4 in the fourth set.

And the tough Croat then moved in for the kill, eventually winning 6-7(2), 6-4, 4-6, 7-5, 7-6(4).

“I have to be honest and say that I was really lucky. I made some unbelievable returns and I was a little bit lucky at the end,” Coric said.

“In the third and fourth set, he was playing unbelievable tennis and I felt like I had no chance.

“In the fifth-set tie-break, I knew it was not going to be easy for him, so I tried to just keep the ball in court and make him play as many balls as possible.”
