Ugo Humbert upset the odds by overcoming Andrey Rublev to win the Halle Open title, clinching his first ATP 500-level trophy in the process.
Unseeded Humbert already claimed the scalp of Alexander Zverev earlier in the week and, having seen off Felix Auger-Aliassime to reach the final, came out on top against world number seven Rublev 6-3 7-6 (7-4).
Rublev was appearing in his eighth final since the start of 2020, though it was his first on grass. The Russian was seeking a fifth successive victory in an ATP 500 level final, yet ultimately came up short, meaning Humbert made it three wins from three in his career finals.
The 22-year-old won his first two titles – in ATP 250 events in Antwerp and Auckland – last year.
Humbert's victory took just 87 minutes, with the Frenchman winning 45 of 53 points on his first serve.
The only break of the game went Humbert's way when he struck to make it 5-3 in the first set before holding off two break points in the next game to take the lead.
Neither player offered a single break point in the second set, and it was Humbert who nosed himself in the tie-break to secure a third career triumph, becoming the first player to win the Halle Open on his debut at the tournament since Lleyton Hewitt defeated Roger Federer in 2010.
Humbert's win will also take him up six places in the ATP rankings, from 31 to 25.
