19 of the Russian's 21 titles have been achieved on hardcourt
A resurgent Medvedev won his initial championship for nearly 30 months with a win over opponent Moutet in the tournament final.
The athlete, a former top-ranked player, has had a challenging season, winning just a single victory at the major tournaments and undergoing a meltdown at the New York tournament.
The player's inconsistency on the ATP Tour - and struggles with his serve in specific - caused him exiting of the world's top 10 and ultimately parting ways with former mentor his previous coach.
Presently collaborating with Johansson and his other coach, he has steadily improved in the last few weeks - climaxing in a closely contested competitive triumph over Frenchman Moutet.
It is his maiden championship since the Italian tournament and maiden on a hard court since that period of that year.
Victory also signifies Medvedev has secured twenty-one victories at 21 various competitions.
"It's the first time I am participating in a event with my two daughters together, so to get a championship is really nice," said ranked player Medvedev.
"This title is in honour of my child Victoria, because the first title I got when my older daughter my daughter was born was for her."
Medvedev, the past champion, had failed in his previous six finals, featuring in Halle in the past months.
His defensive strategy and regular outbursts on court had prompted commentators to doubt if his ability to compete at the highest level was concluded.
Yet the player has made changes in recent weeks, striving to advance forward and compete assertively, backed up by an better serve.
The champion fought back from a deficit in the opening set against the challenging Moutet, taking 4 of the final five games to go ahead.
Both players exchanged breaks in the second set before Moutet, striving for his initial tour title, took control to push for a third set.
Moutet saved four early break points in a competitive final set before the Russian secured a break to that score to serve for the match.
Suitably, Medvedev secured the win with a rally at the net area, with his opponent incapable to control a shot after over two and a half hours.
