19 of the Russian's 21 victories have been earned on hardcourt
A resurgent the Russian player won his maiden title for 882 days with success over Frenchman Moutet in the tournament title decider.
The athlete, a ex- number one, has endured a difficult year, achieving just a single victory at the big events and undergoing a difficult moment at the New York tournament.
The player's unpredictability on the tennis tour - and difficulties with his service game in particular - led to him exiting of the world's top 10 and eventually separating with former trainer his previous coach.
Presently training with his coach and Goetzke, he has gradually improved in the last few weeks - climaxing in a tightly fought 7-5 4-6 6-3 victory over opponent Corentin Moutet.
It is the player's maiden title since the Rome competition and initial on a hard court after spring of the previous year.
Success also indicates the Russian has achieved 21 championships at twenty-one distinct tournaments.
"This marks the first occasion I'm at a competition with my both daughters together, so to secure a trophy is particularly special," said world number 14 the champion.
"This title is in tribute of my second daughter her name, because the first title I got when my child her name was born was for her."
The tennis star, the past champion, had been defeated in his last six championship matches, including in the German tournament in the past months.
The player's counter-punching play style and regular reactions on court had caused commentators to wonder if his ability to compete at the top level was concluded.
But the athlete has implemented adjustments in the last few weeks, attempting to come to the net and play positively, backed up by an enhanced serving game.
He came back from a break down in the first set against the challenging Frenchman, taking four of the final five points to gain the advantage.
Both players traded service breaks in the second set before the challenger, attempting for his maiden ATP Tour championship, seized the initiative to create a third set.
He rescued 4 initial opportunities in a tight third set before Medvedev secured a break to 15 to secure the win.
Suitably, the winner secured victory with a shot at the front of the court, with the Frenchman unable to control a volley after two hours and 38 minutes.
