Nineteen of Daniil Medvedev's 21 victories have been achieved on hardcourt
A revitalized Medvedev won his initial title for 882 days with victory over Frenchman Moutet in the tournament championship match.
The Russian, a former world number one, has had a challenging season, managing just one match at the big events and undergoing a setback at the New York tournament.
His inconsistency on the tennis tour - and difficulties with his serving in especial - led to him exiting of the world's top 10 and ultimately parting ways with former coach Gilles Cervara.
Presently training with Johansson and his other coach, Medvedev has gradually improved in the recent weeks - culminating in a closely contested competitive win over Frenchman Moutet.
This marks the player's first title since the Italian tournament and maiden on a hardcourt from spring of that year.
The win also signifies he has achieved twenty-one titles at 21 different tournaments.
"It's the first time I'm at a event with my two daughters together, so to win a championship is particularly special," commented tennis professional the champion.
"This championship is in honour of my younger daughter Victoria, because the first title I won when my first daughter Alisa was born was for her."
The tennis star, the 2021 US Open champion, had lost his past six title deciders, featuring in that event earlier this year.
The player's counter-punching play style and frequent outbursts on the tennis court had prompted observers to wonder if his ability to play at the elite level was concluded.
However the player has altered his approach in the last few weeks, making an effort to advance forward and play positively, reinforced by an enhanced service.
Medvedev recovered from a deficit in the first set against the difficult Moutet, winning four of the concluding five games to take the lead.
The competitors swapped break points in the middle set before Moutet, attempting for his first professional championship, gained dominance to create a final set.
He saved four early-game break points in a close third set before the Russian won the break to fifteen to close out the victory.
Appropriately, Medvedev earned victory with a shot at the front of the court, with his opponent unable to manage a return after over two and a half hours.
