Nineteen of Medvedev's twenty-one victories have been earned on hardcourt
A resurgent Medvedev secured his first championship for nearly 30 months with a win over opponent Moutet in the competition final.
The Russian, a former top-ranked player, has experienced a difficult year, achieving just a single victory at the big events and suffering a meltdown at the American major.
His inconsistency on the professional circuit - and difficulties with his serve in especial - caused him dropping out of the world's top 10 and finally separating with long-term mentor his previous coach.
Now collaborating with Thomas Johansson and his other coach, the tennis star has consistently progressed in the last few weeks - culminating in a tightly fought three-set victory over challenger Moutet.
This represents his first championship since the Rome competition and maiden on a hard surface after spring of that year.
Victory also indicates the Russian has achieved twenty-one championships at 21 distinct events.
"This marks the first occasion I'm at a tournament with my children together, so to win a title is particularly special," said ranked player Medvedev.
"This championship is in tribute of my second daughter my daughter, because the first title I achieved when my older daughter her name was born was for her."
The tennis star, the former major winner, had been defeated in his previous six title deciders, including in Halle previously this season.
The player's defensive play style and regular reactions on the tennis court had led commentators to question if his ability to compete at the top level was over.
But the athlete has altered his approach in recent weeks, attempting to advance forward and perform aggressively, supported by an better serving game.
He recovered from a disadvantage in the opening set against the tricky Frenchman, winning 4 of the final five exchanges to go ahead.
The pair traded service breaks in the second set before the challenger, bidding for his initial ATP Tour championship, took control to push for a decider.
He rescued 4 initial break points in a close third set before the champion secured a break to 15 to close out the victory.
Fittingly, Medvedev earned victory with a rally at the net, with the Frenchman failing to handle a volley after over two and a half hours.
