Karen Khachanov upset Tomas Berdych 6-3 6-2 to reach the Marseille Open final.
He will next play Lucas Pouille, who reached his second final of the season after a 6-3 7-6 defeat of Ilya Ivashka.
Khachanov was impeccable on serve, saving the meager three break points Berdych had throughout the duel.
The 21-year-old has now beaten Berdych in both their meetings having also prevailed at last year's French Open.
