Dobey ended up winning 3-2 in sets and will next play Michael Van Gerwen, to continue what has been a ground breaking tournament for the Bedlington ace.
'Hollywood' spoke afterwards and said that he felt great out on stage, and that he's got the belief going into facing Mighty Mike.
"It's great to go out there and show what I can do. I felt great up there, I was a bit patchy at times but I finished well," said Dobey.
"It's put me into my first semi-final and to beat the number ten in the world is great, especially after beating Gary [Anderson] too.
"I've got all the belief in the world and I'm playing well enough to go all the way but I'll just focus on the semis now, whoever I play. I will never look past my next game and I will prepare myself like I would for any other game."
