Eklent Kaci claimed the UK Open Pool Championship after hammering defending champion Joshua Filler 13-4 in the final at the Copper Box Arena on Sunday.
Kaci, who suffered a heartbreaking defeat to Ko Pin Yi at the World Pool Masters just a few weeks ago made amends to tame favourite Filler.
"I feel amazing," said the Albanian. "This is the first singles event that I have won in the Matchroom arena.
"I felt focused and I stayed calm. I played the right shots with no crazy efforts and played safe when I needed to.
"Joshua didn't have many chances and when you stay in the chair for too long, you do not feel comfortable.
"I feel I will be a bigger problem in Matchroom events now. A few weeks ago, I played the final of the World Pool Masters. I felt I didn't give him a hard final."
At 4-4, Kaci took firm control of the contest by winning the next six racks to move 10-4 ahead.
Filler was then handed a rare opportunity at the table but he saw his jump effort on the three wide of the mark and Kaci swooped in to seal a memorable win.
He said: "Of course I am disappointed but when you see someone play like that, you have to say he's the deserved winner.
"He kept me in the chair, I was the first-row spectator! I am happy with my overall performance over the week. Well deserved to Eklent, he played unbelievable."
