Nineteen of Daniil Medvedev's twenty-one victories have been won on hard surfaces
A resurgent Medvedev claimed his initial championship for nearly 30 months with success over Frenchman Moutet in the tournament final.
The Russian, a ex- world number one, has had a torrid year, achieving just one match at the big events and undergoing a setback at the US Open.
The player's unpredictability on the professional circuit - and issues with his serve in especial - resulted in him dropping out of the top ten and finally splitting with long-term coach his previous coach.
Now working with his coach and Goetzke, the tennis star has steadily advanced in the past month - peaking in a hard-fought 7-5 4-6 6-3 victory over opponent Moutet.
It is his first championship since the Rome competition and initial on a hardcourt from that period of the previous year.
The win also signifies Medvedev has secured twenty-one victories at twenty-one distinct tournaments.
"This marks the first occasion I'm at a event with my children at once, so to win a championship is particularly special," commented ranked player Medvedev.
"This championship is in dedication of my younger daughter her name, because the initial championship I won when my child her name was delivered was for her."
Medvedev, the 2021 US Open champion, had failed in his last six finals, featuring in the German tournament earlier this year.
The player's retrieving strategy and regular reactions on the playing surface had caused observers to doubt if his skill to compete at the top level was concluded.
But the 29-year-old has made changes in the last few weeks, attempting to approach the net and play aggressively, backed up by an improved service.
Medvedev fought back from a break down in the opening set against the difficult Moutet, winning four of the concluding five points to go ahead.
The competitors exchanged breaks in the second set before the challenger, bidding for his maiden professional victory, took control to create a decider.
He rescued four early-game opportunities in a close third set before the champion broke to 15 to close out the victory.
Fittingly, Medvedev secured the title with a rally at the net area, with his opponent unable to handle a shot after a lengthy match.
