Nineteen of Medvedev's 21 victories have been won on hard surfaces
A revitalized the Russian player secured his maiden trophy for 882 days with a win over Frenchman Moutet in the competition title decider.
The athlete, a former world number one, has had a difficult period, managing just a single victory at the major tournaments and undergoing a meltdown at the US Open.
His unpredictability on the ATP Tour - and difficulties with his serving in particular - resulted in him exiting of the world's top 10 and ultimately splitting with long-term mentor his previous coach.
Presently collaborating with his coach and Rohan Goetzke, he has gradually progressed in the past month - culminating in a hard-fought three-set triumph over Frenchman Corentin Moutet.
This marks the player's first trophy following the 2023 Rome Masters and first on a hard surface since March of that year.
Success also signifies the Russian has secured 21 championships at 21 distinct events.
"It's the first time I have attended a event with my children together, so to secure a championship is really nice," stated tennis professional the champion.
"This victory is in tribute of my second daughter her name, because the maiden victory I achieved when my older daughter her name was delivered was for her."
The tennis star, the 2021 US Open champion, had lost his last six championship matches, including in that event previously this season.
Medvedev's counter-punching play style and recurring reactions on court had led some to wonder if his skill to perform at the highest level was over.
However the athlete has implemented adjustments in the past month, attempting to come to the net and compete assertively, reinforced by an improved service.
Medvedev recovered from a deficit in the opening set against the challenging opponent, taking four of the last five games to gain the advantage.
Both players exchanged break points in the second set before the challenger, striving for his first ATP Tour title, gained dominance to force a third set.
He defended 4 initial break points in a tight deciding set before the Russian secured a break to 15 to serve for the match.
Fittingly, Medvedev secured the win with a shot at the front of the court, with the Frenchman failing to manage a return after two hours and 38 minutes.
