19 of the Russian's 21 championships have been won on hardcourt
A comeback the Russian player won his maiden championship for over two years with a win over Frenchman Moutet in the tournament championship match.
Medvedev, a former world number one, has endured a challenging year, winning just one match at the big events and undergoing a setback at the American major.
The player's unpredictability on the ATP Tour - and struggles with his serving in particular - resulted in him exiting of the top ten and ultimately parting ways with long-time mentor his previous coach.
Presently working with Johansson and Rohan Goetzke, the tennis star has steadily advanced in the recent weeks - peaking in a hard-fought 7-5 4-6 6-3 triumph over Frenchman Moutet.
This marks the player's first championship since the Rome competition and first on a hard court after spring of 2023.
Victory also signifies the Russian has won 21 championships at 21 various competitions.
"This marks the first occasion I am participating in a competition with my both daughters at once, so to get a championship is particularly special," said world number 14 the champion.
"This victory is in dedication of my younger daughter her name, because the maiden victory I won when my child Alisa was born was for her."
Medvedev, the former major winner, had lost his last six finals, featuring in the German tournament in the past months.
His counter-punching strategy and regular reactions on court had led commentators to question if his capacity to play at the highest level was over.
However the athlete has implemented adjustments in recent weeks, striving to come to the net and perform positively, reinforced by an improved service.
Medvedev recovered from a break down in the initial set against the challenging Frenchman, winning four of the last five points to take the lead.
The competitors swapped service breaks in the middle set before Moutet, striving for his initial tour championship, took control to push for a decider.
The opponent saved 4 early opportunities in a tight final set before Medvedev secured a break to 15 to secure the win.
Appropriately, Medvedev clinched the title with a point at the net area, with his opponent unable to control a shot after two hours and 38 minutes.
