The Dutch sensation averaged just under 100 as he won a potentially tricky tie to reach the quarter-finals at London’s Alexandra Palace.
The first two sets were shared before van Gerwen edged ahead by clinching the third with a 76 finish.
The Dutchman fell two legs behind in the fourth set but checkouts of 76 and 72 saw him pull level before he pinned double eight to lead by three sets to one.
And van Gerwen completed a convincing victory when he took out 65 in the deciding leg in the fifth set.
“I was very pleased with that,” said the world number one, who will take on Robert Thornton or Benito van de Pas in the last eight.
“I’m here to defend my title and Terry has beat me in a couple of big tournaments this year. I couldn’t let that happen in this one.
“I feel like I am getting better with each game so I’m already looking forward to the next one.”
