19 of Daniil Medvedev's twenty-one championships have been won on hard surfaces
A resurgent the Russian player secured his first title for 882 days with victory over Frenchman Moutet in the competition championship match.
The Russian, a ex- world number one, has had a torrid period, achieving just one match at the big events and experiencing a difficult moment at the American major.
His inconsistency on the tennis tour - and difficulties with his serving in especial - led to him falling of the elite rankings and ultimately separating with long-term mentor his previous coach.
Now collaborating with Johansson and Rohan Goetzke, the tennis star has steadily progressed in the last few weeks - peaking in a closely contested three-set triumph over opponent Moutet.
This marks Medvedev's initial title after the 2023 Rome Masters and maiden on a hard surface after that period of the previous year.
Victory also signifies the Russian has won 21 championships at twenty-one distinct tournaments.
"For the first time I'm at a event with my children simultaneously, so to secure a trophy is particularly special," stated world number 14 Medvedev.
"This title is in honour of my second daughter Victoria, because the maiden victory I won when my older daughter my daughter was born was for her."
The athlete, the former major winner, had failed in his past six championship matches, including in the German tournament in the past months.
The player's counter-punching approach and recurring reactions on court had led commentators to doubt if his skill to play at the top level was concluded.
But the 29-year-old has altered his approach in the past month, attempting to approach the net and compete assertively, supported by an better serving game.
The champion recovered from a break down in the first set against the difficult Frenchman, winning four of the last five games to gain the advantage.
The competitors traded break points in the middle set before the challenger, bidding for his initial tour championship, gained dominance to create a third set.
The opponent saved four initial break points in a close final set before the champion broke to 15 to serve for the match.
Appropriately, Medvedev earned the win with a point at the net area, with the Frenchman unable to manage a return after two hours and 38 minutes.
