19 of the Russian's 21 titles have been earned on hardcourt
A revitalized Medvedev claimed his initial trophy for nearly 30 months with victory over Frenchman Moutet in the tournament final.
Medvedev, a ex- number one, has experienced a challenging season, achieving just one match at the Grand Slams and undergoing a setback at the American major.
The player's unpredictability on the tennis tour - and issues with his serving in especial - caused him exiting of the world's top 10 and eventually parting ways with long-term trainer Cervara.
Presently training with Thomas Johansson and Rohan Goetzke, he has consistently progressed in the past month - culminating in a hard-fought three-set triumph over challenger Moutet.
This marks Medvedev's first title after the Italian tournament and initial on a hardcourt after March of the previous year.
The win also indicates Medvedev has achieved twenty-one victories at twenty-one various competitions.
"It's the first time I am participating in a event with my both daughters simultaneously, so to get a championship is especially meaningful," commented world number 14 Daniil Medvedev.
"This victory is in dedication of my second daughter Victoria, because the maiden victory I got when my older daughter her name was born was for her."
Medvedev, the former major winner, had failed in his previous six championship matches, featuring in that event in the past months.
The player's counter-punching approach and frequent reactions on the tennis court had caused some to question if his ability to play at the elite level was finished.
Yet the player has made changes in recent weeks, making an effort to approach the net and compete positively, supported by an improved service.
The champion fought back from a break down in the initial set against the tricky opponent, taking 4 of the concluding five games to go ahead.
The competitors exchanged breaks in the following set before the challenger, attempting for his maiden tour victory, gained dominance to create a final set.
Moutet defended four initial opportunities in a tight final set before Medvedev won the break to 15 to secure the win.
Fittingly, he clinched the title with a point at the net, with the Frenchman failing to handle a volley after two hours and 38 minutes.
