Cameron Norrie fell to Borna Coric in straight sets in their semi-final match in Cincinnati, ending his run in the masters tournament.
Norrie was defeated 6-3 6-4 by the Croatian, who will play Stefanos Tsitsipas in the final.
The Briton had beaten Spanish third seed Carlos Alcaraz 7-6 (4) 6-7 (4) 6-4 to set up a last-four showdown with Coric.
Norrie admitted he lost focus before battling his way back from the brink of defeat to book the semi-final.
Norrie told the ATP Tour’s official website: “That was unbelievable. Credit to Carlos. I was up a set and a break, 4-1, and I kind of lost a little bit of vision.”
