Nineteen of the Russian's twenty-one titles have been won on hard surfaces
A revitalized Daniil Medvedev secured his first championship for nearly 30 months with victory over Frenchman Moutet in the competition final.
The athlete, a ex- top-ranked player, has endured a difficult year, winning just a single victory at the major tournaments and experiencing a difficult moment at the American major.
His unpredictability on the tennis tour - and struggles with his service game in especial - caused him exiting of the elite rankings and finally parting ways with former mentor Gilles Cervara.
Now collaborating with Thomas Johansson and Rohan Goetzke, Medvedev has consistently progressed in the past month - climaxing in a closely contested three-set win over challenger Moutet.
This marks Medvedev's maiden title after the Italian tournament and maiden on a hardcourt after spring of that year.
Victory also means he has achieved 21 victories at twenty-one different competitions.
"This marks the first occasion I have attended a competition with my both daughters simultaneously, so to win a title is especially meaningful," said tennis professional Medvedev.
"This victory is in dedication of my second daughter her name, because the initial championship I got when my first daughter Alisa was born was for her."
Medvedev, the former major winner, had lost his past six title deciders, featuring in Halle previously this season.
The player's defensive approach and recurring emotional displays on the playing surface had prompted observers to wonder if his skill to perform at the top level was concluded.
Yet the athlete has made changes in recent weeks, attempting to come to the net and play aggressively, supported by an better serving game.
Medvedev recovered from a deficit in the initial set against the tricky Frenchman, taking four of the final five games to take the lead.
The competitors exchanged breaks in the middle set before the challenger, attempting for his first professional championship, seized the initiative to create a final set.
He defended 4 initial chances in a competitive third set before the Russian secured a break to fifteen to close out the victory.
Suitably, Medvedev earned the win with a shot at the net, with the Frenchman failing to manage a shot after two hours and 38 minutes.
