19 of the Russian's twenty-one victories have been won on hard surfaces
A resurgent the Russian player secured his initial trophy for over two years with a win over opponent Moutet in the competition championship match.
The athlete, a ex- world number one, has endured a torrid year, achieving just a single victory at the big events and experiencing a setback at the New York tournament.
The player's unpredictability on the ATP Tour - and struggles with his serve in particular - caused him dropping out of the world's top 10 and finally parting ways with long-time coach Gilles Cervara.
Now working with Thomas Johansson and Goetzke, he has gradually improved in the recent weeks - climaxing in a tightly fought three-set triumph over Frenchman Corentin Moutet.
This marks the player's initial title after the 2023 Rome Masters and initial on a hardcourt from spring of that year.
Victory also means he has won 21 victories at 21 different competitions.
"This marks the first occasion I am participating in a event with my both daughters simultaneously, so to win a championship is especially meaningful," said world number 14 the champion.
"This victory is in dedication of my younger daughter my daughter, because the maiden victory I got when my first daughter her name was delivered was for her."
The tennis star, the former major winner, had lost his last six title deciders, comprising in that event in the past months.
The player's counter-punching approach and frequent emotional displays on court had caused some to doubt if his capacity to perform at the highest level was concluded.
Yet the player has made changes in the past month, striving to advance forward and compete positively, supported by an improved serving game.
He fought back from a disadvantage in the opening set against the difficult Moutet, securing four of the final five exchanges to go ahead.
Both players exchanged breaks in the middle set before the Frenchman, attempting for his maiden tour victory, seized the initiative to force a decider.
He rescued 4 initial chances in a close final set before the Russian broke to fifteen to secure the win.
Fittingly, he earned the win with a shot at the net, with Moutet failing to control a return after a lengthy match.
