Webster defeated fellow World Champions Stephen Bunting, Adrian Lewis and Jelle Klaasen in a sensational run to the last four before bowing out at the hands of world number one van Gerwen.
The Welsh ace felt he could have performed better in the 4-1 reverse but is delighted with his return to form.
He said: “I was annoyed with myself after the semi-final because it was the worst I’d played but credit to Michael. He did the job and that’s why he’s the world number one.
“Before the tournament if someone had offered me a semi-final place I would have snapped their hand off but once you’re in that position, you want to kick on and win the tournament.
“I think I’ve shown that I’ve still got the pedigree to beat these top players. I’ve been putting the hard work in behind the scenes and it is starting to pay off so that is what I will continue to do.”
