Nineteen of the Russian's twenty-one championships have been won on hard surfaces
A resurgent the Russian player secured his maiden trophy for 882 days with success over Frenchman Moutet in the competition championship match.
The Russian, a former top-ranked player, has experienced a challenging season, achieving just a single victory at the Grand Slams and experiencing a meltdown at the US Open.
His unpredictability on the ATP Tour - and struggles with his serving in specific - caused him dropping out of the elite rankings and ultimately parting ways with former trainer Gilles Cervara.
Now working with Thomas Johansson and Goetzke, the tennis star has steadily progressed in the recent weeks - climaxing in a hard-fought three-set victory over opponent Moutet.
This represents his first title after the 2023 Rome Masters and first on a hard surface since spring of the previous year.
Success also signifies the Russian has achieved twenty-one victories at twenty-one various competitions.
"It's the first time I am participating in a competition with my children together, so to win a title is especially meaningful," said world number 14 the champion.
"This championship is in dedication of my second daughter her name, because the first title I got when my first daughter my daughter was born was for her."
The athlete, the 2021 US Open champion, had lost his previous six title deciders, including in the German tournament in the past months.
The player's defensive approach and recurring reactions on the playing surface had led commentators to question if his skill to compete at the elite level was finished.
Yet the athlete has altered his approach in recent weeks, striving to advance forward and compete aggressively, backed up by an enhanced service.
The champion came back from a deficit in the initial set against the challenging Moutet, winning four of the concluding five exchanges to gain the advantage.
The pair swapped service breaks in the middle set before Moutet, attempting for his first ATP Tour championship, gained dominance to create a final set.
Moutet defended 4 early break points in a tight deciding set before the Russian secured a break to that score to close out the victory.
Suitably, he secured the win with a point at the front of the court, with Moutet unable to manage a shot after two hours and 38 minutes.
