Novak Djokovic will have a chance to avenge his Wimbledon final defeat to Carlos Alcaraz when the pair meet in the Cincinnati Open final.
World number one Alcaraz saved match point before going on to beat Poland's Hubert Hurkacz 2-6 7-6 (7-4) 6-3 in Saturday's semi-final.
Then the world number two Djokovic overcame Germany's Alexander Zverev 7-6 (7-5) 7-5 to set up the Alcaraz match.
"It's the ultimate challenge at the moment for me," Djokovic said.
Spain's Alcaraz, 20, beat the Serb in five sets in last month's Wimbledon final and has won two of their three meetings to date.
