19 of Medvedev's twenty-one championships have been achieved on hardcourt
A comeback the Russian player won his first trophy for nearly 30 months with success over Frenchman Moutet in the competition final.
Medvedev, a former top-ranked player, has endured a difficult period, managing just one win at the Grand Slams and undergoing a meltdown at the New York tournament.
His varied form on the professional circuit - and issues with his serving in especial - resulted in him dropping out of the elite rankings and ultimately separating with long-time coach Cervara.
Now collaborating with Johansson and his other coach, the tennis star has consistently advanced in the past month - climaxing in a closely contested three-set win over challenger Moutet.
It is his maiden title after the Rome competition and initial on a hardcourt after spring of the previous year.
Success also signifies the Russian has secured twenty-one championships at 21 various tournaments.
"It's the first time I'm at a tournament with my both daughters at once, so to get a championship is really nice," commented tennis professional the champion.
"This victory is in dedication of my younger daughter her name, because the maiden victory I got when my first daughter her name was delivered was for her."
Medvedev, the past champion, had been defeated in his past six title deciders, featuring in Halle previously this season.
His retrieving play style and recurring reactions on the tennis court had prompted commentators to question if his capacity to perform at the highest level was over.
However the athlete has altered his approach in the last few weeks, striving to approach the net and play aggressively, supported by an better serving game.
He fought back from a break down in the opening set against the challenging Moutet, winning 4 of the final five exchanges to take the lead.
The pair traded service breaks in the following set before the challenger, attempting for his maiden professional victory, seized the initiative to create a decider.
The opponent rescued four early opportunities in a tight third set before the Russian secured a break to that score to serve for the match.
Appropriately, the winner clinched victory with a point at the net area, with the Frenchman unable to handle a shot after two hours and 38 minutes.
