Nineteen of Daniil Medvedev's twenty-one championships have been earned on hardcourt
A resurgent the Russian player secured his initial title for 882 days with success over Frenchman Moutet in the tournament final.
Medvedev, a ex- top-ranked player, has endured a torrid year, managing just one win at the major tournaments and undergoing a setback at the American major.
Medvedev's unpredictability on the ATP Tour - and difficulties with his serve in especial - caused him dropping out of the top ten and eventually parting ways with long-time mentor his previous coach.
Currently working with his coach and his other coach, he has gradually improved in the past month - climaxing in a hard-fought competitive win over challenger Corentin Moutet.
It is Medvedev's maiden title after the Italian tournament and first on a hard surface since spring of the previous year.
Success also means the Russian has won twenty-one titles at 21 distinct events.
"It's the first time I have attended a tournament with my children at once, so to get a championship is particularly special," commented tennis professional Daniil Medvedev.
"This victory is in honour of my child my daughter, because the first title I achieved when my child my daughter was born was for her."
Medvedev, the former major winner, had lost his past six finals, featuring in Halle previously this season.
The player's counter-punching approach and recurring reactions on court had prompted observers to wonder if his skill to perform at the elite level was finished.
But the athlete has implemented adjustments in the past month, attempting to advance forward and play assertively, supported by an enhanced serving game.
The champion fought back from a break down in the initial set against the difficult Frenchman, securing four of the last five points to take the lead.
The pair swapped break points in the middle set before the Frenchman, striving for his maiden tour championship, took control to create a final set.
The opponent defended 4 initial break points in a close final set before Medvedev broke to fifteen to secure the win.
Appropriately, the winner earned the title with a point at the front of the court, with Moutet incapable to manage a return after over two and a half hours.
