Nineteen of Daniil Medvedev's 21 championships have been earned on hard surfaces
A comeback the Russian player won his first championship for 882 days with success over Frenchman Moutet in the tournament title decider.
Medvedev, a ex- top-ranked player, has endured a difficult period, achieving just one win at the Grand Slams and undergoing a difficult moment at the New York tournament.
His inconsistency on the ATP Tour - and difficulties with his serving in particular - caused him exiting of the top ten and finally splitting with long-term trainer his previous coach.
Currently working with Thomas Johansson and his other coach, the tennis star has gradually progressed in the past month - peaking in a hard-fought three-set win over challenger Moutet.
This marks his first championship since the 2023 Rome Masters and maiden on a hard court after March of 2023.
Success also signifies he has secured twenty-one championships at twenty-one distinct events.
"This marks the first occasion I have attended a event with my two daughters together, so to get a title is especially meaningful," stated world number 14 the champion.
"This championship is in dedication of my child Victoria, because the first title I got when my first daughter Alisa was born was for her."
Medvedev, the 2021 US Open champion, had lost his previous six title deciders, featuring in Halle in the past months.
Medvedev's retrieving strategy and regular emotional displays on court had led commentators to doubt if his ability to compete at the highest level was finished.
But the athlete has made changes in recent weeks, making an effort to approach the net and play aggressively, reinforced by an enhanced serving game.
Medvedev came back from a break down in the first set against the difficult Moutet, securing four of the concluding five exchanges to go ahead.
The competitors exchanged breaks in the second set before Moutet, bidding for his first tour victory, took control to create a decider.
Moutet rescued 4 early opportunities in a tight final set before the Russian secured a break to fifteen to serve for the match.
Suitably, the winner clinched the win with a point at the net, with the Frenchman failing to handle a shot after two hours and 38 minutes.
