Nineteen of the Russian's twenty-one titles have been earned on hardcourt
A comeback Medvedev won his initial trophy for over two years with victory over opponent Moutet in the competition final.
The athlete, a former top-ranked player, has had a difficult season, managing just one win at the major tournaments and experiencing a setback at the American major.
His unpredictability on the ATP Tour - and issues with his serve in especial - caused him dropping out of the world's top 10 and finally separating with long-term trainer Cervara.
Presently training with his coach and Goetzke, the tennis star has gradually improved in the last few weeks - peaking in a tightly fought three-set triumph over Frenchman Moutet.
This represents the player's initial title after the Italian tournament and maiden on a hard surface since spring of that year.
Success also indicates Medvedev has won twenty-one victories at 21 various events.
"For the first time I'm at a tournament with my two daughters together, so to secure a championship is especially meaningful," stated ranked player Daniil Medvedev.
"This victory is in dedication of my younger daughter her name, because the maiden victory I achieved when my child Alisa was delivered was for her."
The athlete, the past champion, had been defeated in his last six finals, including in Halle previously this season.
The player's defensive strategy and frequent reactions on court had caused observers to wonder if his capacity to play at the highest level was concluded.
But the player has implemented adjustments in recent weeks, striving to come to the net and play assertively, reinforced by an enhanced service.
Medvedev came back from a disadvantage in the first set against the challenging Frenchman, taking four of the last five points to go ahead.
The competitors traded service breaks in the following set before the Frenchman, attempting for his initial ATP Tour championship, took control to create a decider.
The opponent saved four initial opportunities in a tight final set before Medvedev broke to fifteen to serve for the match.
Appropriately, Medvedev clinched victory with a point at the net area, with Moutet incapable to control a return after a lengthy match.
