19 of Medvedev's 21 championships have been won on hard surfaces
A revitalized Medvedev claimed his initial trophy for 882 days with success over Frenchman Moutet in the competition final.
Medvedev, a ex- top-ranked player, has endured a challenging year, managing just a single victory at the Grand Slams and undergoing a setback at the US Open.
His unpredictability on the tennis tour - and issues with his serve in particular - caused him exiting of the top ten and ultimately splitting with long-term trainer Cervara.
Presently working with his coach and his other coach, he has consistently improved in the recent weeks - culminating in a hard-fought three-set win over opponent Moutet.
This marks the player's initial title after the Rome competition and initial on a hardcourt from March of the previous year.
The win also indicates Medvedev has secured twenty-one victories at twenty-one various events.
"It's the first time I'm at a competition with my both daughters simultaneously, so to secure a title is particularly special," commented ranked player Medvedev.
"This victory is in tribute of my child my daughter, because the maiden victory I achieved when my first daughter my daughter was born was for her."
Medvedev, the 2021 US Open champion, had lost his previous six championship matches, including in the German tournament in the past months.
His defensive strategy and recurring emotional displays on the playing surface had prompted commentators to wonder if his ability to play at the elite level was finished.
But the player has implemented adjustments in recent weeks, striving to come to the net and play assertively, supported by an enhanced serve.
The champion recovered from a disadvantage in the opening set against the challenging opponent, taking 4 of the concluding five points to gain the advantage.
Both players exchanged service breaks in the following set before the challenger, attempting for his maiden ATP Tour title, took control to force a final set.
Moutet defended 4 initial opportunities in a competitive third set before Medvedev won the break to that score to close out the victory.
Fittingly, Medvedev secured the title with a rally at the front of the court, with the Frenchman unable to handle a volley after over two and a half hours.
