In a game that lasted 63 minutes, Federer was too much for Hyeon but he was not happy with the way the semi-final clash ended.
“I know he has had a problem with a blister, I've played with them a lot and they hurt a lot,” Federer said after the game.
“It is better to stop. I'm incredibly happy to be in the final but not like this. He has had such a wonderful tournament.”
In the final, Federer will now face Croatian Marin Cilic who defeat Kyle Edmund in the other semi-final on Thursday, January 25.
