Herbert wins over Tsitsipas in Marseille and will face Humbert in the semis A small sensation in Marseille: Frenchman Pierre-Hugues Herbert has won over Greek Stefanos Tsitsipas, the world's fifth-ranked player, and will face a compatriot, Ugo Humbert, who defeated another Frenchman, Arthur Rinderknech, in the evening final. The other semi-final will pit Russia's Daniil Medvedev, the world's No.1 seed, against Australia's Matthew Ebden. Medvedev easily defeated Italy's Jannick Sinner 6-2, 6-4, while Ebden pulled off an upset over Russia's Karen Khachanov, seeded No.3, losing 4-6, 6-4, 6-2. But the sensation of the day came from Pierre-Hugues Herbert, who scored the biggest win of his career against Tsitsipas in three sets 6-7 (6/8), 6-4, 6-2. The Frenchman, who is currently 93rd in the ATP rankings, is a doubles specialist - he has won the Grand Slam in his career with Nicolas Mahut - and did not give up after losing the first set in a tie-break. "At 4-4 in the second set, I played a very good game to break him and from then on I played very well. I had to go to the net, I had to do something, be aggressive, I couldn't win from the baseline. It worked. I'm very happy with this victory," said the Frenchman. "There will be a Frenchman in the final, that's good. I hope it will be me," he concluded. He will have to get past Ugo Humbert, world No.31, who won the French quarter-final with authority against Arthur Rinderknech in three sets 4-6, 7-5, 7-6 (7/4). Humbert, seeded No.4, had to work hard to eliminate his compatriot, ranked 138th in the world, after rejecting a match point.
