19 of Medvedev's 21 victories have been earned on hardcourt
A revitalized the Russian player secured his maiden title for over two years with a win over Frenchman Moutet in the tournament final.
The athlete, a ex- world number one, has experienced a challenging season, winning just a single victory at the Grand Slams and suffering a meltdown at the American major.
His varied form on the professional circuit - and struggles with his service game in particular - caused him dropping out of the world's top 10 and eventually parting ways with long-term coach Gilles Cervara.
Presently working with his coach and Rohan Goetzke, the tennis star has consistently progressed in the last few weeks - climaxing in a hard-fought 7-5 4-6 6-3 victory over challenger Moutet.
This marks his maiden title since the Italian tournament and initial on a hard court since that period of the previous year.
Success also signifies Medvedev has secured 21 titles at twenty-one various competitions.
"This marks the first occasion I have attended a competition with my children at once, so to get a title is really nice," commented ranked player Medvedev.
"This title is in tribute of my child my daughter, because the initial championship I won when my older daughter Alisa was born was for her."
The athlete, the former major winner, had been defeated in his past six championship matches, including in the German tournament in the past months.
The player's counter-punching approach and regular outbursts on the playing surface had prompted commentators to wonder if his skill to perform at the elite level was over.
However the athlete has made changes in the last few weeks, attempting to come to the net and play positively, reinforced by an enhanced serving game.
The champion fought back from a disadvantage in the first set against the challenging Frenchman, winning four of the last five points to gain the advantage.
The pair traded service breaks in the following set before Moutet, bidding for his initial tour title, took control to force a third set.
The opponent defended 4 early-game chances in a close third set before Medvedev won the break to 15 to serve for the match.
Suitably, the winner earned the title with a rally at the net area, with his opponent unable to manage a return after a lengthy match.
