Nineteen of Daniil Medvedev's 21 titles have been won on hardcourt
A revitalized the Russian player secured his maiden championship for 882 days with victory over opponent Moutet in the competition final.
The athlete, a ex- top-ranked player, has endured a torrid season, managing just one win at the major tournaments and suffering a difficult moment at the American major.
The player's varied form on the tennis tour - and difficulties with his serve in especial - resulted in him exiting of the top ten and eventually separating with long-term coach his previous coach.
Currently collaborating with Thomas Johansson and Goetzke, Medvedev has steadily progressed in the last few weeks - culminating in a closely contested three-set win over Frenchman Moutet.
This marks the player's first championship following the Rome competition and first on a hard court after that period of that year.
Victory also means he has won 21 victories at 21 different tournaments.
"This marks the first occasion I have attended a competition with my both daughters together, so to win a championship is especially meaningful," commented tennis professional Daniil Medvedev.
"This title is in tribute of my second daughter her name, because the first title I got when my first daughter Alisa was born was for her."
Medvedev, the past champion, had lost his last six championship matches, including in Halle previously this season.
Medvedev's retrieving play style and regular emotional displays on court had prompted commentators to wonder if his ability to perform at the highest level was over.
But the athlete has altered his approach in recent weeks, striving to approach the net and play positively, supported by an improved service.
Medvedev came back from a break down in the first set against the challenging opponent, securing 4 of the last five points to go ahead.
The pair swapped service breaks in the middle set before the Frenchman, bidding for his maiden ATP Tour championship, took control to create a final set.
Moutet defended four early opportunities in a competitive final set before the Russian won the break to that score to secure the win.
Suitably, the winner earned the win with a rally at the net area, with his opponent incapable to control a shot after over two and a half hours.
