The Dutch ace, who was crowned Masters champion last month, reached all three finals of the first UK Open Qualifiers at Robin Park, winning Saturday’s and Sunday’s tournaments.
van Gerwen stormed into Friday’s final but was denied victory by Adrian Lewis.
The world number one got his revenge the following day as he defeated Lewis en route to the final, where he saw off compatriot Vincent van der Voort, missing double twelve for a nine-darter in the last leg of his 6-1 win.
And he struck again on Sunday, this time beating James Wade 6-1 in the decider.
The 2014 World Champion has lost just one of his 25 games since suffering a semi-final defeat at the World Championship this year.
“I’m very happy with my form,” said van Gerwen, who faces Stephen Bunting in the Premier League on Thursday.
“I had a short break after the Worlds and I feel good and ready to do a lot of damage this year.
“I already have a TV title and now two Pro Tours under my belt but this is just the start of what I hope will be a fantastic year for me.”
