19 of the Russian's 21 championships have been earned on hardcourt
A resurgent Daniil Medvedev won his initial title for 882 days with a win over Frenchman Moutet in the tournament championship match.
Medvedev, a ex- world number one, has had a torrid period, managing just a single victory at the major tournaments and experiencing a meltdown at the American major.
The player's inconsistency on the ATP Tour - and issues with his service game in specific - led to him exiting of the world's top 10 and finally parting ways with long-time coach Cervara.
Now working with his coach and Goetzke, the tennis star has steadily improved in the last few weeks - peaking in a closely contested competitive victory over Frenchman Moutet.
This marks his maiden title after the Rome competition and initial on a hard surface after March of that year.
Success also means the Russian has won twenty-one victories at 21 various competitions.
"For the first time I am participating in a event with my both daughters together, so to win a championship is particularly special," commented world number 14 the champion.
"This title is in honour of my second daughter Victoria, because the first title I achieved when my child her name was born was for her."
Medvedev, the 2021 US Open champion, had lost his previous six championship matches, comprising in Halle previously this season.
Medvedev's counter-punching play style and recurring reactions on the playing surface had caused commentators to wonder if his ability to play at the highest level was over.
Yet the player has altered his approach in the past month, attempting to approach the net and compete aggressively, supported by an improved service.
The champion came back from a deficit in the opening set against the difficult opponent, winning four of the concluding five points to take the lead.
The competitors exchanged service breaks in the middle set before Moutet, attempting for his initial tour championship, took control to force a third set.
He rescued four initial opportunities in a competitive final set before the champion won the break to fifteen to serve for the match.
Appropriately, he clinched the title with a rally at the net, with his opponent failing to handle a return after a lengthy match.
