Sorry Doddle.

Pretty much perfect snooker.

What a phenomenal time for him.
Well done.
I watched a lot of it, and was glad that he got it done. I was pleased Ronnie compared him to Tony Drago during his semi-final, a view I share. He's had such a clattering from commentators over the years, so it's good that he put it together.
