Stefanos Tsitsipas beat Mikhail Kukushkin 7-5, 7-6 (5) to win the Open 13 title in Marseille.
Tsitsipas delivered 14 aces but still had to fight off the Kazakhstan native in a second-set tiebreaker to prevail.
Kukushkin had two aces while failing to win his second career title.
"I lost the spark [after the Australian Open] and I was frustrated because it felt like I couldn't find it again," said Tsitsipas. "This week, I can say I am really happy because I felt this hunger back again... I really hope it stays the same because there are many good players out there that play for the same prize."
"Winning titles is the thing that I am working for... It is the biggest satisfaction and the biggest joy in tennis," said Tsitsipas.
"[I have] satisfaction. There was a lot of stress this week because I knew I had to face some good opponents... When you care a lot, you tend to be more stressed than usual. I am happy that I got through that stress and played the game that I was supposed to play," said Tsitsipas.
Kukushkin gains 150 ATP Ranking points and earns €47,105. Tsitsipas collects 250 ATP Ranking points and receives €89,435 in prize money.
