Nineteen of Daniil Medvedev's 21 titles have been earned on hard courts
A resurgent Medvedev claimed his initial title for 882 days with victory over opponent Moutet in the tournament title decider.
Medvedev, a former world number one, has had a torrid period, winning just one match at the major tournaments and experiencing a difficult moment at the US Open.
The player's inconsistency on the professional circuit - and difficulties with his serve in specific - caused him exiting of the elite rankings and eventually parting ways with long-term mentor Gilles Cervara.
Presently training with his coach and Rohan Goetzke, the tennis star has steadily progressed in the past month - climaxing in a closely contested competitive victory over opponent Corentin Moutet.
It is Medvedev's first championship since the Rome competition and first on a hard surface from that period of that year.
Success also means Medvedev has won twenty-one titles at twenty-one distinct competitions.
"For the first time I am participating in a competition with my two daughters simultaneously, so to win a championship is particularly special," commented ranked player Daniil Medvedev.
"This victory is in dedication of my younger daughter Victoria, because the maiden victory I won when my first daughter my daughter was born was for her."
The tennis star, the past champion, had lost his previous six title deciders, including in the German tournament previously this season.
The player's defensive approach and recurring reactions on court had led commentators to question if his ability to play at the highest level was finished.
However the 29-year-old has altered his approach in the last few weeks, making an effort to approach the net and perform aggressively, supported by an better serving game.
Medvedev came back from a disadvantage in the first set against the difficult Moutet, securing four of the final five games to go ahead.
Both players traded breaks in the second set before the Frenchman, striving for his maiden ATP Tour title, gained dominance to force a decider.
He saved four early-game opportunities in a competitive third set before the Russian secured a break to fifteen to serve for the match.
Appropriately, the winner clinched the title with a rally at the net, with the Frenchman failing to control a return after over two and a half hours.
