19 of the Russian's twenty-one victories have been won on hard courts
A resurgent the Russian player claimed his first trophy for over two years with victory over Frenchman Moutet in the tournament title decider.
The Russian, a former number one, has had a difficult period, winning just one match at the Grand Slams and experiencing a meltdown at the American major.
Medvedev's inconsistency on the tennis tour - and struggles with his serving in particular - resulted in him falling of the elite rankings and finally separating with long-term trainer Gilles Cervara.
Now working with Thomas Johansson and his other coach, Medvedev has steadily advanced in the last few weeks - climaxing in a tightly fought three-set victory over opponent Moutet.
This represents the player's maiden trophy following the Rome competition and first on a hardcourt from March of the previous year.
Victory also indicates the Russian has secured 21 victories at 21 different events.
"This marks the first occasion I'm at a tournament with my two daughters simultaneously, so to secure a trophy is particularly special," commented tennis professional the champion.
"This title is in honour of my child her name, because the first title I won when my child her name was delivered was for her."
The tennis star, the 2021 US Open champion, had failed in his previous six title deciders, featuring in Halle in the past months.
Medvedev's retrieving strategy and frequent emotional displays on court had prompted observers to wonder if his ability to perform at the top level was concluded.
However the player has made changes in the last few weeks, striving to approach the net and compete aggressively, supported by an enhanced serve.
He came back from a deficit in the initial set against the difficult Moutet, winning four of the final five games to go ahead.
The pair exchanged breaks in the second set before the challenger, bidding for his initial ATP Tour championship, gained dominance to create a third set.
The opponent defended 4 initial chances in a competitive final set before the Russian broke to 15 to serve for the match.
Appropriately, the winner secured the win with a point at the front of the court, with his opponent unable to handle a return after over two and a half hours.
