Nineteen of Medvedev's 21 championships have been earned on hard surfaces
A comeback Medvedev claimed his initial title for over two years with victory over Frenchman Moutet in the competition final.
The Russian, a ex- number one, has endured a torrid period, managing just one win at the Grand Slams and experiencing a difficult moment at the US Open.
The player's inconsistency on the tennis tour - and struggles with his service game in specific - led to him dropping out of the world's top 10 and eventually separating with long-term trainer Cervara.
Currently working with his coach and his other coach, he has consistently progressed in the past month - peaking in a hard-fought competitive win over challenger Moutet.
This represents his initial trophy after the Rome competition and maiden on a hard court from March of that year.
Success also signifies the Russian has secured twenty-one victories at twenty-one distinct events.
"This marks the first occasion I'm at a tournament with my two daughters simultaneously, so to get a trophy is really nice," stated ranked player the champion.
"This title is in honour of my younger daughter my daughter, because the first title I got when my older daughter my daughter was born was for her."
Medvedev, the former major winner, had been defeated in his last six title deciders, featuring in the German tournament previously this season.
The player's counter-punching play style and recurring outbursts on the tennis court had caused observers to wonder if his skill to play at the highest level was finished.
Yet the 29-year-old has implemented adjustments in recent weeks, making an effort to come to the net and perform positively, reinforced by an improved serve.
The champion fought back from a disadvantage in the first set against the tricky Frenchman, securing four of the final five exchanges to gain the advantage.
Both players traded breaks in the second set before the challenger, striving for his maiden tour victory, gained dominance to push for a final set.
The opponent rescued 4 early-game opportunities in a tight final set before Medvedev broke to fifteen to close out the victory.
Fittingly, the winner clinched the win with a rally at the net area, with the Frenchman incapable to handle a shot after two hours and 38 minutes.
