Nineteen of the Russian's 21 victories have been won on hard surfaces
A resurgent the Russian player claimed his first title for over two years with a win over opponent Moutet in the competition championship match.
The Russian, a former number one, has had a difficult period, winning just one match at the big events and undergoing a difficult moment at the American major.
His inconsistency on the tennis tour - and issues with his serving in specific - led to him exiting of the world's top 10 and finally splitting with long-term mentor Cervara.
Currently collaborating with Johansson and Goetzke, the tennis star has consistently advanced in the last few weeks - peaking in a closely contested 7-5 4-6 6-3 triumph over challenger Moutet.
It is Medvedev's maiden trophy since the Rome competition and maiden on a hardcourt from spring of the previous year.
Success also signifies he has secured twenty-one championships at twenty-one distinct tournaments.
"This marks the first occasion I am participating in a event with my both daughters at once, so to secure a title is really nice," commented world number 14 Medvedev.
"This title is in tribute of my child her name, because the initial championship I achieved when my first daughter her name was born was for her."
The tennis star, the 2021 US Open champion, had lost his previous six title deciders, including in Halle in the past months.
His retrieving strategy and regular outbursts on the tennis court had prompted observers to doubt if his skill to compete at the top level was concluded.
However the 29-year-old has altered his approach in the past month, making an effort to advance forward and play positively, reinforced by an improved serve.
The champion came back from a deficit in the initial set against the difficult Frenchman, securing four of the last five points to take the lead.
The pair traded service breaks in the middle set before the challenger, striving for his initial ATP Tour title, seized the initiative to push for a third set.
He saved four initial chances in a close deciding set before the champion secured a break to fifteen to secure the win.
Appropriately, the winner clinched the win with a shot at the front of the court, with the Frenchman failing to control a shot after a lengthy match.
