Nineteen of Daniil Medvedev's twenty-one titles have been won on hardcourt
A resurgent Medvedev won his initial trophy for 882 days with a win over Frenchman Moutet in the tournament championship match.
The Russian, a ex- number one, has had a difficult year, managing just one match at the major tournaments and experiencing a meltdown at the American major.
The player's inconsistency on the ATP Tour - and struggles with his service game in particular - caused him falling of the top ten and finally separating with long-time coach Cervara.
Currently working with his coach and Rohan Goetzke, the tennis star has gradually improved in the last few weeks - culminating in a closely contested competitive win over challenger Moutet.
This marks his maiden championship since the Italian tournament and initial on a hard surface since spring of that year.
Success also means Medvedev has won 21 championships at twenty-one distinct events.
"This marks the first occasion I'm at a competition with my two daughters together, so to get a championship is particularly special," said tennis professional Daniil Medvedev.
"This championship is in tribute of my second daughter her name, because the first title I got when my older daughter my daughter was born was for her."
The athlete, the former major winner, had lost his previous six championship matches, comprising in Halle in the past months.
Medvedev's counter-punching play style and recurring outbursts on the tennis court had prompted observers to question if his capacity to compete at the highest level was concluded.
Yet the 29-year-old has implemented adjustments in recent weeks, making an effort to come to the net and perform assertively, supported by an improved service.
Medvedev came back from a deficit in the opening set against the tricky opponent, taking 4 of the final five points to take the lead.
The competitors traded break points in the second set before the challenger, bidding for his first ATP Tour title, seized the initiative to create a final set.
He rescued four initial opportunities in a close deciding set before Medvedev secured a break to that score to secure the win.
Fittingly, he earned the win with a shot at the front of the court, with the Frenchman unable to handle a shot after two hours and 38 minutes.
