Petersen utilising European Tour success as European Championship run continues: "I'm just carrying on with that winning mentality and confidence"
Petersen claimed his maiden European Tour title earlier this year and has continued that form into the season ending event.
He spoke afterwards and admitted he has carried on that mentality into future events and he is looking to claim the title if he can keep it up.
"I'm happy that the game didn't ignite. If it did it would've been a tougher scenario," said Petersen.
"I knew Ian's first dart was slightly high and I tried to jump on that, which actually impeded the way I was playing.
"I kept letting him in. I felt like I had the upper-hand but I wasn't showing it until the 143 went in.
"I've always dreamt of being a champion on the PDC tour, and when I achieved that it validated my hard work. Now I'm just carrying on with that winning mentality and confidence.
"If I keep it going, who knows, I could be the one lifting the trophy tomorrow night."
