Nineteen of Medvedev's twenty-one victories have been earned on hard surfaces
A resurgent the Russian player secured his maiden title for nearly 30 months with a win over Frenchman Moutet in the tournament championship match.
Medvedev, a ex- number one, has endured a difficult year, winning just one match at the Grand Slams and suffering a difficult moment at the American major.
His unpredictability on the professional circuit - and struggles with his serving in especial - caused him falling of the top ten and finally parting ways with long-time mentor Gilles Cervara.
Currently training with Thomas Johansson and his other coach, Medvedev has steadily improved in the recent weeks - climaxing in a hard-fought three-set triumph over challenger Moutet.
This represents the player's maiden championship after the Rome competition and initial on a hard surface after that period of that year.
The win also means Medvedev has secured twenty-one titles at twenty-one various tournaments.
"For the first time I am participating in a event with my two daughters at once, so to secure a championship is particularly special," said ranked player Daniil Medvedev.
"This victory is in tribute of my child her name, because the initial championship I won when my older daughter my daughter was born was for her."
The tennis star, the 2021 US Open champion, had failed in his last six finals, including in Halle in the past months.
His counter-punching approach and frequent reactions on court had caused observers to doubt if his skill to perform at the elite level was over.
But the 29-year-old has made changes in the past month, striving to advance forward and play assertively, supported by an enhanced service.
He fought back from a deficit in the first set against the challenging Frenchman, securing 4 of the concluding five points to gain the advantage.
The competitors swapped service breaks in the second set before the Frenchman, bidding for his first tour title, took control to force a final set.
The opponent defended 4 early-game break points in a close deciding set before Medvedev won the break to fifteen to close out the victory.
Appropriately, he clinched the title with a point at the front of the court, with his opponent unable to handle a return after over two and a half hours.
