Nineteen of the Russian's 21 titles have been earned on hardcourt
A comeback Medvedev secured his first title for over two years with victory over opponent Moutet in the competition title decider.
The Russian, a ex- number one, has endured a torrid season, achieving just one match at the major tournaments and undergoing a setback at the American major.
The player's inconsistency on the professional circuit - and issues with his serve in especial - caused him dropping out of the elite rankings and finally separating with long-term mentor Cervara.
Presently training with his coach and Rohan Goetzke, the tennis star has consistently advanced in the recent weeks - climaxing in a closely contested competitive win over opponent Corentin Moutet.
This represents his initial trophy after the Italian tournament and initial on a hard court since March of 2023.
Success also signifies the Russian has won twenty-one championships at 21 distinct competitions.
"For the first time I am participating in a competition with my children together, so to win a trophy is really nice," said world number 14 the champion.
"This victory is in tribute of my child my daughter, because the first title I achieved when my older daughter her name was delivered was for her."
The tennis star, the past champion, had failed in his previous six finals, including in Halle in the past months.
Medvedev's retrieving play style and regular reactions on court had led commentators to wonder if his skill to perform at the highest level was concluded.
However the player has made changes in the last few weeks, striving to come to the net and play positively, backed up by an improved service.
The champion recovered from a deficit in the opening set against the challenging Moutet, winning 4 of the final five games to take the lead.
The competitors exchanged break points in the middle set before the Frenchman, attempting for his initial professional victory, gained dominance to push for a final set.
He rescued four early chances in a tight third set before the Russian won the break to 15 to serve for the match.
Suitably, Medvedev secured the title with a rally at the front of the court, with his opponent failing to control a volley after a lengthy match.
