Nineteen of Daniil Medvedev's 21 titles have been earned on hardcourt
A comeback the Russian player secured his initial championship for 882 days with victory over opponent Moutet in the competition final.
The Russian, a former world number one, has experienced a difficult year, winning just one win at the big events and suffering a meltdown at the New York tournament.
Medvedev's varied form on the tennis tour - and difficulties with his service game in specific - resulted in him falling of the world's top 10 and ultimately parting ways with long-term mentor Cervara.
Now collaborating with his coach and his other coach, Medvedev has steadily improved in the last few weeks - culminating in a hard-fought competitive victory over Frenchman Moutet.
This marks his initial title since the Rome competition and initial on a hard surface from that period of the previous year.
The win also signifies the Russian has won 21 championships at twenty-one various tournaments.
"This marks the first occasion I have attended a competition with my both daughters simultaneously, so to win a trophy is particularly special," commented tennis professional the champion.
"This victory is in honour of my second daughter her name, because the initial championship I got when my older daughter my daughter was born was for her."
The athlete, the 2021 US Open champion, had lost his previous six title deciders, including in Halle in the past months.
The player's retrieving play style and frequent outbursts on the playing surface had caused commentators to wonder if his skill to perform at the elite level was over.
However the player has implemented adjustments in the past month, making an effort to come to the net and play aggressively, reinforced by an better serving game.
He came back from a break down in the first set against the difficult Moutet, winning 4 of the concluding five points to go ahead.
The competitors exchanged break points in the second set before Moutet, bidding for his first professional championship, gained dominance to force a decider.
Moutet rescued four initial opportunities in a close third set before Medvedev broke to 15 to secure the win.
Appropriately, he secured the win with a point at the net area, with Moutet failing to handle a shot after over two and a half hours.
