19 of the Russian's 21 victories have been achieved on hard courts
A resurgent the Russian player secured his first title for 882 days with victory over Frenchman Moutet in the competition final.
The athlete, a former number one, has experienced a difficult year, winning just a single victory at the major tournaments and suffering a difficult moment at the American major.
Medvedev's inconsistency on the tennis tour - and difficulties with his serve in specific - caused him exiting of the top ten and ultimately parting ways with long-time trainer Gilles Cervara.
Now collaborating with Johansson and his other coach, Medvedev has consistently advanced in the recent weeks - culminating in a hard-fought three-set win over opponent Moutet.
This represents his first championship since the Italian tournament and initial on a hardcourt from spring of 2023.
Victory also means Medvedev has secured 21 victories at twenty-one various competitions.
"This marks the first occasion I am participating in a competition with my children at once, so to win a title is particularly special," stated world number 14 the champion.
"This championship is in dedication of my child Victoria, because the initial championship I won when my older daughter her name was born was for her."
Medvedev, the past champion, had failed in his last six title deciders, comprising in Halle previously this season.
The player's counter-punching play style and recurring emotional displays on the playing surface had led commentators to wonder if his skill to compete at the top level was over.
But the 29-year-old has implemented adjustments in the past month, making an effort to come to the net and compete positively, backed up by an improved service.
Medvedev came back from a deficit in the first set against the tricky Frenchman, winning 4 of the last five exchanges to gain the advantage.
Both players exchanged service breaks in the middle set before Moutet, bidding for his maiden professional victory, gained dominance to create a final set.
The opponent defended four early-game break points in a competitive final set before the champion secured a break to 15 to close out the victory.
Fittingly, he secured the win with a rally at the net area, with his opponent unable to manage a return after two hours and 38 minutes.
