19 of Medvedev's twenty-one championships have been won on hard surfaces
A resurgent the Russian player won his initial trophy for over two years with a win over Frenchman Moutet in the competition final.
Medvedev, a ex- number one, has had a challenging period, winning just one win at the big events and suffering a meltdown at the US Open.
Medvedev's inconsistency on the ATP Tour - and difficulties with his serving in particular - resulted in him falling of the top ten and finally parting ways with long-time mentor Gilles Cervara.
Now working with Johansson and his other coach, he has consistently improved in the recent weeks - peaking in a hard-fought three-set victory over opponent Moutet.
This marks Medvedev's maiden championship after the Italian tournament and initial on a hardcourt from spring of the previous year.
The win also indicates Medvedev has secured twenty-one championships at twenty-one various competitions.
"For the first time I'm at a competition with my two daughters simultaneously, so to win a title is especially meaningful," stated ranked player the champion.
"This victory is in dedication of my second daughter my daughter, because the first title I got when my older daughter Alisa was delivered was for her."
The tennis star, the past champion, had lost his previous six finals, comprising in the German tournament previously this season.
The player's defensive approach and frequent reactions on the playing surface had prompted commentators to question if his capacity to play at the highest level was concluded.
Yet the 29-year-old has altered his approach in the past month, making an effort to approach the net and play aggressively, supported by an improved serving game.
The champion came back from a deficit in the first set against the challenging Frenchman, winning four of the concluding five games to go ahead.
Both players exchanged service breaks in the second set before the challenger, striving for his maiden tour victory, seized the initiative to force a final set.
He rescued four early chances in a competitive deciding set before the Russian won the break to fifteen to serve for the match.
Suitably, he earned the title with a rally at the net, with his opponent unable to control a shot after over two and a half hours.
