Nineteen of the Russian's 21 victories have been earned on hard courts
A revitalized the Russian player claimed his maiden championship for nearly 30 months with a win over Frenchman Moutet in the competition title decider.
Medvedev, a former number one, has endured a torrid period, achieving just a single victory at the big events and experiencing a meltdown at the New York tournament.
His unpredictability on the ATP Tour - and difficulties with his serve in especial - caused him falling of the top ten and eventually parting ways with long-term trainer his previous coach.
Currently training with Johansson and Rohan Goetzke, the tennis star has gradually improved in the past month - peaking in a hard-fought three-set win over opponent Corentin Moutet.
This represents Medvedev's initial title since the Italian tournament and initial on a hard surface after March of that year.
The win also signifies Medvedev has won 21 titles at twenty-one different tournaments.
"This marks the first occasion I'm at a tournament with my two daughters at once, so to get a championship is particularly special," commented tennis professional Medvedev.
"This title is in tribute of my second daughter Victoria, because the maiden victory I achieved when my older daughter my daughter was born was for her."
The tennis star, the former major winner, had failed in his previous six title deciders, comprising in the German tournament earlier this year.
His retrieving play style and frequent outbursts on the playing surface had prompted observers to wonder if his skill to play at the elite level was concluded.
However the player has altered his approach in the last few weeks, making an effort to advance forward and compete assertively, supported by an improved serving game.
Medvedev recovered from a disadvantage in the first set against the difficult opponent, winning 4 of the last five games to go ahead.
The competitors exchanged breaks in the following set before Moutet, striving for his initial tour title, gained dominance to force a decider.
Moutet rescued 4 early break points in a close final set before Medvedev won the break to 15 to serve for the match.
Fittingly, the winner secured victory with a point at the front of the court, with Moutet unable to handle a shot after two hours and 38 minutes.
