Nineteen of Daniil Medvedev's twenty-one titles have been won on hardcourt
A revitalized the Russian player claimed his initial trophy for over two years with success over Frenchman Moutet in the tournament final.
Medvedev, a ex- world number one, has had a difficult year, winning just one win at the big events and experiencing a setback at the US Open.
Medvedev's inconsistency on the professional circuit - and difficulties with his serving in especial - caused him dropping out of the elite rankings and ultimately separating with long-time mentor Gilles Cervara.
Presently working with his coach and his other coach, he has gradually improved in the past month - climaxing in a hard-fought 7-5 4-6 6-3 victory over challenger Moutet.
This represents his first title following the Italian tournament and maiden on a hard court since March of that year.
Victory also signifies he has secured 21 victories at 21 distinct tournaments.
"This marks the first occasion I'm at a event with my both daughters together, so to win a championship is particularly special," said ranked player Medvedev.
"This title is in honour of my child Victoria, because the first title I got when my child her name was born was for her."
The tennis star, the past champion, had failed in his last six finals, featuring in Halle in the past months.
Medvedev's defensive strategy and frequent reactions on the playing surface had caused observers to wonder if his ability to play at the elite level was concluded.
However the player has implemented adjustments in recent weeks, attempting to advance forward and compete positively, backed up by an enhanced serving game.
Medvedev recovered from a break down in the initial set against the tricky Moutet, securing 4 of the last five points to take the lead.
The pair exchanged break points in the second set before the Frenchman, bidding for his initial ATP Tour title, took control to push for a third set.
Moutet rescued 4 early chances in a tight deciding set before Medvedev secured a break to that score to serve for the match.
Fittingly, Medvedev secured the win with a rally at the net, with the Frenchman incapable to control a volley after a lengthy match.
