Nineteen of Medvedev's twenty-one championships have been achieved on hardcourt
A comeback Medvedev won his maiden trophy for 882 days with success over Frenchman Moutet in the competition championship match.
The Russian, a former number one, has had a torrid year, managing just a single victory at the big events and experiencing a setback at the American major.
His inconsistency on the professional circuit - and difficulties with his serving in specific - caused him dropping out of the top ten and ultimately splitting with long-time trainer Gilles Cervara.
Presently collaborating with Johansson and Goetzke, he has gradually progressed in the past month - culminating in a hard-fought 7-5 4-6 6-3 win over Frenchman Corentin Moutet.
This represents the player's maiden title since the Italian tournament and maiden on a hard court from that period of 2023.
Success also indicates Medvedev has secured twenty-one victories at twenty-one distinct events.
"It's the first time I have attended a event with my both daughters together, so to win a trophy is especially meaningful," said tennis professional Medvedev.
"This title is in honour of my second daughter Victoria, because the first title I won when my older daughter her name was born was for her."
The athlete, the 2021 US Open champion, had been defeated in his last six championship matches, featuring in Halle previously this season.
The player's retrieving strategy and frequent outbursts on the tennis court had caused observers to doubt if his skill to play at the highest level was finished.
But the athlete has made changes in recent weeks, striving to advance forward and perform positively, supported by an enhanced serve.
Medvedev fought back from a disadvantage in the initial set against the difficult opponent, securing four of the concluding five exchanges to gain the advantage.
Both players swapped break points in the following set before the Frenchman, striving for his initial ATP Tour championship, gained dominance to push for a third set.
The opponent saved 4 early-game break points in a competitive final set before Medvedev won the break to that score to serve for the match.
Suitably, he clinched the title with a shot at the net, with his opponent incapable to manage a shot after over two and a half hours.
