Nineteen of Medvedev's 21 championships have been won on hardcourt
A resurgent Medvedev won his maiden championship for nearly 30 months with a win over opponent Moutet in the competition title decider.
Medvedev, a ex- world number one, has experienced a challenging season, winning just one match at the Grand Slams and suffering a setback at the US Open.
His unpredictability on the tennis tour - and struggles with his service game in particular - led to him dropping out of the elite rankings and finally splitting with former trainer Cervara.
Now collaborating with Thomas Johansson and Rohan Goetzke, the tennis star has consistently advanced in the recent weeks - culminating in a tightly fought three-set victory over challenger Corentin Moutet.
This marks his initial title following the Rome competition and first on a hard surface since March of the previous year.
Victory also means he has achieved twenty-one victories at twenty-one distinct tournaments.
"This marks the first occasion I am participating in a event with my both daughters at once, so to win a title is particularly special," commented ranked player the champion.
"This championship is in tribute of my child my daughter, because the first title I got when my child Alisa was born was for her."
The athlete, the former major winner, had lost his last six finals, comprising in Halle previously this season.
Medvedev's defensive play style and recurring outbursts on the playing surface had caused observers to wonder if his ability to compete at the top level was finished.
Yet the athlete has implemented adjustments in the past month, attempting to advance forward and compete aggressively, supported by an better serving game.
He came back from a deficit in the first set against the tricky Moutet, taking four of the concluding five points to gain the advantage.
Both players swapped breaks in the middle set before the Frenchman, bidding for his first ATP Tour title, gained dominance to create a decider.
Moutet saved 4 early-game opportunities in a close third set before the Russian broke to 15 to secure the win.
Appropriately, Medvedev secured victory with a point at the net area, with the Frenchman failing to manage a volley after over two and a half hours.
