Jose de Sousa is through to the second round at the 2021 European Championship after seeing off Lewy Williams grounding out a 6-4 win.
Williams missed six darts for a 3-1 lead and De Sousa took hold of the tie from there winning through 6-4.
He believed experience told and also discussed a noticeable change in not wearing glasses on the oche.
"He started very well but I think after that he started to become a little bit nervous," De Sousa suggested.
"I had to control the game because in the first round it's hard but I did a good job.
"He is a brilliant player but the game is what it is, and it was for me this time.
"Right now I feel much better without glasses. I'm okay, I see well and have no problem so I can play well."
