Nineteen of Daniil Medvedev's 21 titles have been won on hardcourt
A revitalized Medvedev won his initial championship for 882 days with a win over Frenchman Moutet in the competition final.
The athlete, a ex- world number one, has had a difficult season, winning just a single victory at the big events and suffering a meltdown at the American major.
His varied form on the ATP Tour - and difficulties with his serve in especial - caused him falling of the elite rankings and ultimately splitting with long-term coach Cervara.
Currently training with Thomas Johansson and his other coach, Medvedev has gradually improved in the recent weeks - peaking in a tightly fought competitive win over challenger Moutet.
It is his maiden title following the Italian tournament and first on a hardcourt from spring of the previous year.
Victory also indicates the Russian has achieved 21 championships at twenty-one different events.
"It's the first time I have attended a competition with my both daughters simultaneously, so to get a title is really nice," commented ranked player Daniil Medvedev.
"This championship is in tribute of my younger daughter my daughter, because the maiden victory I won when my child Alisa was born was for her."
Medvedev, the past champion, had failed in his past six title deciders, comprising in the German tournament earlier this year.
The player's defensive play style and frequent outbursts on the tennis court had caused commentators to question if his skill to play at the elite level was concluded.
But the 29-year-old has altered his approach in the past month, striving to advance forward and compete positively, supported by an better serve.
He came back from a deficit in the initial set against the tricky Frenchman, winning 4 of the concluding five exchanges to go ahead.
The pair exchanged breaks in the second set before the Frenchman, bidding for his maiden professional victory, seized the initiative to force a final set.
The opponent rescued four early chances in a close third set before the champion broke to that score to secure the win.
Fittingly, the winner earned the title with a shot at the net area, with the Frenchman failing to manage a volley after a lengthy match.
