19 of Medvedev's twenty-one championships have been won on hard surfaces
A revitalized the Russian player won his initial trophy for nearly 30 months with victory over Frenchman Moutet in the competition title decider.
The Russian, a former number one, has had a torrid period, winning just one win at the big events and suffering a difficult moment at the US Open.
Medvedev's inconsistency on the tennis tour - and issues with his service game in particular - resulted in him exiting of the elite rankings and ultimately splitting with former trainer his previous coach.
Currently working with Thomas Johansson and Rohan Goetzke, Medvedev has gradually improved in the past month - peaking in a tightly fought competitive triumph over challenger Moutet.
This marks his maiden trophy following the Italian tournament and maiden on a hardcourt from March of that year.
Victory also indicates Medvedev has secured twenty-one titles at 21 distinct events.
"It's the first time I'm at a tournament with my children simultaneously, so to secure a trophy is especially meaningful," stated world number 14 Daniil Medvedev.
"This title is in honour of my younger daughter her name, because the maiden victory I won when my older daughter Alisa was delivered was for her."
The tennis star, the former major winner, had been defeated in his previous six title deciders, comprising in the German tournament earlier this year.
The player's defensive approach and recurring reactions on court had prompted some to wonder if his ability to perform at the top level was over.
However the athlete has made changes in the past month, striving to approach the net and compete aggressively, reinforced by an improved serving game.
The champion came back from a disadvantage in the first set against the difficult opponent, securing four of the concluding five points to gain the advantage.
The pair exchanged breaks in the middle set before the Frenchman, attempting for his initial ATP Tour victory, gained dominance to push for a final set.
Moutet rescued 4 early-game opportunities in a competitive third set before Medvedev won the break to that score to close out the victory.
Fittingly, the winner earned the win with a rally at the net, with the Frenchman unable to handle a return after two hours and 38 minutes.
