19 of Daniil Medvedev's 21 victories have been achieved on hard surfaces
A resurgent the Russian player claimed his initial title for over two years with victory over Frenchman Moutet in the competition title decider.
The athlete, a ex- top-ranked player, has endured a difficult year, managing just a single victory at the big events and suffering a setback at the US Open.
Medvedev's varied form on the ATP Tour - and difficulties with his serving in particular - caused him exiting of the top ten and eventually separating with former mentor Cervara.
Now training with his coach and Goetzke, Medvedev has gradually improved in the last few weeks - climaxing in a hard-fought competitive win over Frenchman Moutet.
This marks the player's first trophy after the Italian tournament and initial on a hardcourt after that period of that year.
Success also means the Russian has achieved 21 championships at twenty-one distinct events.
"It's the first time I'm at a competition with my children simultaneously, so to secure a title is really nice," stated tennis professional the champion.
"This championship is in tribute of my child my daughter, because the maiden victory I achieved when my older daughter her name was born was for her."
The tennis star, the past champion, had failed in his last six title deciders, featuring in Halle previously this season.
Medvedev's retrieving play style and regular emotional displays on the tennis court had prompted observers to doubt if his capacity to compete at the elite level was over.
However the athlete has implemented adjustments in the last few weeks, attempting to approach the net and play aggressively, reinforced by an enhanced service.
Medvedev fought back from a disadvantage in the first set against the tricky Moutet, winning 4 of the concluding five exchanges to go ahead.
The pair traded break points in the second set before Moutet, striving for his initial ATP Tour title, gained dominance to force a third set.
Moutet saved four early opportunities in a tight third set before the Russian secured a break to that score to secure the win.
Suitably, Medvedev clinched the win with a rally at the net area, with Moutet incapable to handle a shot after two hours and 38 minutes.
