Nineteen of Medvedev's twenty-one victories have been earned on hard surfaces
A revitalized the Russian player secured his first championship for over two years with victory over opponent Moutet in the competition championship match.
The athlete, a ex- top-ranked player, has had a difficult year, achieving just one match at the big events and suffering a meltdown at the US Open.
Medvedev's varied form on the ATP Tour - and struggles with his service game in especial - resulted in him falling of the top ten and finally parting ways with former trainer his previous coach.
Now collaborating with his coach and his other coach, Medvedev has gradually progressed in the recent weeks - culminating in a tightly fought competitive victory over Frenchman Moutet.
This represents his initial trophy since the Rome competition and initial on a hard court from that period of that year.
Victory also means he has achieved 21 titles at 21 different competitions.
"This marks the first occasion I'm at a competition with my children simultaneously, so to get a trophy is really nice," said tennis professional Medvedev.
"This victory is in honour of my younger daughter my daughter, because the maiden victory I got when my first daughter her name was born was for her."
The athlete, the former major winner, had lost his past six title deciders, featuring in Halle in the past months.
His defensive play style and recurring outbursts on the playing surface had prompted some to wonder if his capacity to play at the highest level was finished.
But the player has altered his approach in the past month, attempting to advance forward and compete aggressively, backed up by an enhanced service.
He recovered from a deficit in the initial set against the challenging opponent, winning four of the last five exchanges to go ahead.
Both players exchanged service breaks in the second set before the challenger, attempting for his initial ATP Tour championship, gained dominance to push for a third set.
The opponent saved four early-game chances in a close final set before the Russian secured a break to that score to close out the victory.
Appropriately, he clinched the title with a point at the net area, with Moutet incapable to manage a return after two hours and 38 minutes.
