Nineteen of the Russian's twenty-one titles have been earned on hard surfaces
A resurgent Medvedev secured his first trophy for nearly 30 months with success over Frenchman Moutet in the competition championship match.
The athlete, a ex- top-ranked player, has had a challenging year, managing just a single victory at the big events and suffering a meltdown at the US Open.
His unpredictability on the ATP Tour - and difficulties with his serving in specific - led to him exiting of the top ten and finally separating with long-time mentor Gilles Cervara.
Now collaborating with his coach and his other coach, Medvedev has steadily advanced in the last few weeks - climaxing in a hard-fought 7-5 4-6 6-3 win over Frenchman Moutet.
This marks his first championship following the 2023 Rome Masters and initial on a hard court after spring of 2023.
Success also means Medvedev has achieved twenty-one victories at twenty-one different events.
"For the first time I am participating in a tournament with my both daughters simultaneously, so to secure a title is particularly special," stated world number 14 Daniil Medvedev.
"This victory is in tribute of my second daughter Victoria, because the first title I got when my older daughter her name was born was for her."
The athlete, the 2021 US Open champion, had lost his previous six finals, including in Halle in the past months.
The player's defensive approach and regular emotional displays on the playing surface had prompted some to doubt if his ability to play at the top level was finished.
But the 29-year-old has made changes in the last few weeks, striving to advance forward and compete assertively, reinforced by an better serve.
Medvedev fought back from a deficit in the initial set against the challenging opponent, winning four of the final five exchanges to gain the advantage.
The competitors swapped breaks in the middle set before the challenger, striving for his first ATP Tour title, seized the initiative to create a decider.
The opponent defended 4 early opportunities in a competitive final set before the champion secured a break to 15 to close out the victory.
Appropriately, the winner secured the title with a rally at the net area, with his opponent incapable to manage a shot after over two and a half hours.
