Grigor Dimitrov defeated Lukas Rosol 7-6(2) 6-1 in the BRD Nastase Tiriac Trophy final in Bucharest on Sunday evening.
It took the Bulgarian 81 minutes to end the nine-match winning streak of the defending champion.
Dimitrov, who turned professional in 2008, did not drop a single set in four matches this week to win the third ATP World Tour title of his career.
The top seed was rewarded €77,315 in prize money and a 250-point boost to his Emirates ATP World Ranking, equalling his best-ever world ranking by taking him to number 14.
Currently ranked 51 in the ATP World Rankings and yet to clinch his first title in 2014, Rosol took home €40,720 and 150 Emirates Ranking points.
After claiming his second piece of silverware for the season, Dimitrov reviewed his impressive performance with fondness and has every reason to be confident going into the French Open in late May.
“It feels good to have won,” said the 22-year-old.
“I lifted my game, not having been happy with my previous matches in the tournament. I knew I had to lift my level, especially after the first set.
"Lukas is a very good winner, who hit some outstanding winners. It was a pleasure to play in front of Ilie Nastase and other greats.
“I have worked really hard to start winning titles. I have put in enough effort, time and sacrifices to get here.”
Dimitrov earned a 2-0 lead in the first set before Rosol saved four break points to hold and ensure the tightly contested opener was decided by a tie-break.
However, the Czech offered little resistance in the breaker, conceding the opening five points before the Bulgarian converted his second set point to take the lead in 55 minutes.
Dimitrov carried his momentum into second set by again taking a 2-0 lead in the early stages.
A demoralised Rosol was broken for a third time at 3-1, inviting the 2014 Australian Open quarter-finalist to chalk up his 20th victory of the year and first-ever title on clay-court.
Dimitrov swept aside Jiri Vesely, Sergiy Stakhovsky and Gael Monfils, who retired from their semi-final clash due to an ankle injury, to reach the fourth singles final of his career.
The 22-year-old has tasted defeat in a final only once during his short time on the senior tour, losing at the 2013 Brisbane International to then defending champion Andy Murray.
After conquering Jarko Nieminen, Giles Simon and Robin Haase en route to the last two, Rosol went into the first meeting between the two finalists seeking to become only the second player to secure back-to-back titles at the BRD Nastase Tiriac Trophy clay-court event.
Giles Simon, who won the tournament in 2007 and 2008, is currently the only player to achieve the feat.
Dimitrov, who is currently coached by Australian Roger Rasheed, will continue his preparation for the 2014 Roland Garros at the Madrid Masters beginning the week of 5 May.
