19 of the Russian's twenty-one victories have been won on hardcourt
A comeback Daniil Medvedev secured his maiden title for nearly 30 months with a win over opponent Moutet in the competition title decider.
Medvedev, a former world number one, has endured a torrid year, managing just a single victory at the major tournaments and experiencing a setback at the US Open.
Medvedev's inconsistency on the ATP Tour - and difficulties with his serving in particular - caused him exiting of the world's top 10 and eventually parting ways with long-term coach his previous coach.
Presently training with Johansson and Rohan Goetzke, he has gradually advanced in the recent weeks - climaxing in a tightly fought 7-5 4-6 6-3 win over Frenchman Moutet.
It is his initial trophy after the Italian tournament and maiden on a hardcourt from March of that year.
Success also means Medvedev has achieved twenty-one titles at twenty-one distinct tournaments.
"This marks the first occasion I have attended a competition with my children simultaneously, so to win a championship is really nice," commented ranked player Medvedev.
"This victory is in dedication of my child her name, because the maiden victory I won when my first daughter my daughter was delivered was for her."
The athlete, the former major winner, had failed in his past six title deciders, including in Halle previously this season.
Medvedev's retrieving play style and regular reactions on the tennis court had prompted some to doubt if his skill to perform at the top level was over.
Yet the 29-year-old has made changes in the past month, making an effort to advance forward and perform positively, backed up by an improved serve.
He fought back from a break down in the opening set against the difficult opponent, winning four of the final five exchanges to take the lead.
Both players traded break points in the middle set before the challenger, attempting for his first tour victory, seized the initiative to force a decider.
He rescued four early break points in a close third set before the Russian broke to fifteen to secure the win.
Appropriately, Medvedev clinched the win with a shot at the front of the court, with the Frenchman incapable to manage a shot after a lengthy match.
