Nineteen of Daniil Medvedev's 21 championships have been earned on hard surfaces
A resurgent the Russian player claimed his first title for 882 days with success over Frenchman Moutet in the competition championship match.
The athlete, a ex- world number one, has had a difficult period, achieving just one match at the Grand Slams and suffering a meltdown at the New York tournament.
Medvedev's varied form on the ATP Tour - and struggles with his serve in especial - led to him dropping out of the elite rankings and eventually separating with long-term mentor Gilles Cervara.
Presently collaborating with Thomas Johansson and Goetzke, he has gradually advanced in the past month - peaking in a tightly fought three-set victory over challenger Moutet.
This represents Medvedev's maiden title since the Rome competition and maiden on a hard surface from that period of the previous year.
Success also signifies Medvedev has secured twenty-one championships at 21 different tournaments.
"This marks the first occasion I am participating in a event with my both daughters together, so to win a trophy is especially meaningful," commented world number 14 Daniil Medvedev.
"This championship is in dedication of my second daughter her name, because the initial championship I got when my older daughter my daughter was delivered was for her."
Medvedev, the 2021 US Open champion, had lost his past six championship matches, featuring in that event previously this season.
Medvedev's retrieving strategy and regular outbursts on the tennis court had prompted observers to question if his capacity to play at the highest level was concluded.
However the 29-year-old has made changes in recent weeks, making an effort to approach the net and compete assertively, supported by an better serving game.
The champion recovered from a disadvantage in the first set against the tricky opponent, winning four of the last five points to go ahead.
The pair exchanged breaks in the middle set before the Frenchman, bidding for his first ATP Tour title, gained dominance to create a decider.
Moutet saved 4 initial opportunities in a competitive deciding set before the champion won the break to that score to close out the victory.
Appropriately, the winner clinched the title with a shot at the front of the court, with the Frenchman failing to manage a return after over two and a half hours.
