Nineteen of Medvedev's twenty-one championships have been earned on hardcourt
A resurgent the Russian player claimed his initial title for nearly 30 months with victory over Frenchman Moutet in the tournament title decider.
Medvedev, a former number one, has endured a difficult year, achieving just a single victory at the major tournaments and experiencing a meltdown at the New York tournament.
His unpredictability on the professional circuit - and struggles with his serving in particular - led to him falling of the elite rankings and eventually separating with long-term coach Cervara.
Presently working with Johansson and Rohan Goetzke, the tennis star has consistently progressed in the last few weeks - peaking in a tightly fought competitive victory over opponent Moutet.
This represents the player's maiden title after the Rome competition and maiden on a hardcourt since that period of the previous year.
Victory also means the Russian has achieved twenty-one victories at 21 distinct competitions.
"It's the first time I have attended a tournament with my children at once, so to win a title is particularly special," stated ranked player the champion.
"This championship is in tribute of my younger daughter Victoria, because the initial championship I got when my child her name was born was for her."
Medvedev, the former major winner, had been defeated in his previous six finals, comprising in the German tournament in the past months.
The player's counter-punching approach and regular emotional displays on court had prompted commentators to question if his capacity to compete at the elite level was finished.
But the 29-year-old has implemented adjustments in the past month, attempting to advance forward and compete aggressively, backed up by an better serving game.
The champion fought back from a disadvantage in the opening set against the challenging Moutet, winning four of the final five games to go ahead.
The competitors swapped break points in the following set before Moutet, striving for his first ATP Tour victory, seized the initiative to force a decider.
Moutet saved 4 initial break points in a close third set before Medvedev broke to fifteen to close out the victory.
Suitably, the winner earned the title with a rally at the net, with his opponent incapable to handle a return after over two and a half hours.
