A last gasp qualification attempt saw Petersen average 113 against Gerwyn Price but it still wasn't enough to move into the final which would have gave him the opportunity.

It has been duly noted previously that he has worked with Wayne Mardle and Colin Lloyd to help improve his game; he spoke to the Weekly Dartscast about the process to get to where he is now.

"It started obviously with the technique and understanding from the ground up; so your platform which is your feet and all of these things that obviously people don't look at. I dissected my entire throw and obviously put it back together exactly how I wanted it to be," said Petersen on the Weekly Dartscast.

I think I'm probably about 75% to 80% there now and I think I've still got 20-25% to complete in a sense; but that only comes with time and obviously your body gets to understand that that's the way in which you throw all the time.

Then you are talking about mentality, confidence and understanding that you have to trust the process and once you see the reward, you start trusting the process even more.

Obviously with Colin Lloyd and Wayne Mardle still I'm able to obviously gain from their experience with any questions I have and they quickly respond to me. Obviously a big thing in elite sports is mentorship and coaching which darts players don't really have. It's one of the areas I see that not a lot of dart players have and I think I've embraced it and I'm reaping the rewards."
