Nineteen of Daniil Medvedev's twenty-one victories have been achieved on hard surfaces
A revitalized Medvedev won his initial trophy for 882 days with a win over opponent Moutet in the competition title decider.
Medvedev, a former world number one, has had a difficult season, winning just a single victory at the Grand Slams and undergoing a difficult moment at the US Open.
His unpredictability on the ATP Tour - and struggles with his service game in specific - resulted in him falling of the world's top 10 and eventually splitting with former trainer Cervara.
Presently collaborating with Johansson and his other coach, the tennis star has gradually improved in the last few weeks - culminating in a hard-fought competitive triumph over challenger Moutet.
It is the player's initial trophy after the 2023 Rome Masters and first on a hardcourt after that period of 2023.
Success also indicates he has secured 21 victories at 21 different events.
"This marks the first occasion I'm at a tournament with my two daughters together, so to secure a championship is particularly special," said world number 14 Medvedev.
"This title is in honour of my younger daughter Victoria, because the maiden victory I won when my child Alisa was delivered was for her."
The athlete, the former major winner, had lost his previous six title deciders, featuring in Halle previously this season.
His defensive strategy and recurring outbursts on court had led observers to question if his ability to perform at the top level was over.
Yet the 29-year-old has implemented adjustments in the last few weeks, making an effort to approach the net and perform positively, supported by an better serving game.
The champion fought back from a deficit in the initial set against the difficult Frenchman, taking 4 of the final five games to go ahead.
The competitors swapped service breaks in the middle set before the challenger, bidding for his first tour victory, seized the initiative to create a decider.
The opponent saved four early-game chances in a competitive third set before the champion secured a break to fifteen to secure the win.
Suitably, Medvedev clinched the title with a shot at the front of the court, with the Frenchman failing to control a volley after a lengthy match.
