Nineteen of the Russian's 21 victories have been achieved on hard courts
A revitalized Daniil Medvedev secured his maiden title for 882 days with victory over Frenchman Moutet in the competition title decider.
The Russian, a former world number one, has endured a difficult season, managing just one match at the Grand Slams and undergoing a meltdown at the New York tournament.
Medvedev's varied form on the professional circuit - and struggles with his serve in especial - caused him dropping out of the top ten and finally splitting with long-term trainer Gilles Cervara.
Now training with Thomas Johansson and Rohan Goetzke, Medvedev has consistently advanced in the recent weeks - climaxing in a hard-fought competitive triumph over opponent Corentin Moutet.
It is Medvedev's maiden championship after the Rome competition and initial on a hard surface since spring of 2023.
Success also signifies Medvedev has won twenty-one championships at 21 distinct events.
"This marks the first occasion I am participating in a tournament with my two daughters together, so to win a trophy is really nice," stated world number 14 the champion.
"This championship is in honour of my second daughter my daughter, because the first title I achieved when my older daughter my daughter was born was for her."
Medvedev, the former major winner, had been defeated in his past six title deciders, comprising in Halle earlier this year.
His counter-punching play style and recurring outbursts on the playing surface had prompted some to wonder if his skill to compete at the elite level was over.
Yet the athlete has made changes in the past month, attempting to approach the net and play assertively, supported by an enhanced serving game.
He recovered from a break down in the opening set against the difficult opponent, winning 4 of the final five points to gain the advantage.
The competitors traded breaks in the following set before the Frenchman, bidding for his first professional title, gained dominance to force a final set.
Moutet saved 4 early opportunities in a tight final set before the champion secured a break to that score to serve for the match.
Appropriately, he clinched victory with a rally at the net, with his opponent incapable to handle a return after over two and a half hours.
