The world number one edged closer to winning his first title at the Winter Gardens in high-quality affair, in which both players averaged over 100.
van Gerwen looked fairly comfortable throughout the match thanks to a run of five straight legs from 3-2 down.
But the Dutch sensation believes he will have to improve to defeat James Wade in the final after ‘The Machine’ eliminated Phil Taylor.
“I didn’t play my best game but it was enough,” said the 25-year-old, who will play in the decider for the second consecutive year.
“It will be a tough final but if I play my best game I should win. This could have been more comfortable but I lost concentration a couple of times but I’ll be focused tomorrow. It is one of my main targets this year to win this tournament.”
van Gerwen hit four 180s in the opening six legs, which were shared, before grabbing the first break of throw during a run of five consecutive legs for the Dutchman, as he moved into a 7-3 lead.
Wright then stemmed the tide and van Gerwen pinned double top to stay four legs clear. The pair then held throw in the following two legs and a brilliant 161 finish from ‘Snakebite’ kept him in touching distance.
‘Mighty Mike’ pegged double four before a run of four consecutive breaks of throw left the world number one with a 12-8 advantage.
Another break saw van Gerwen move five legs ahead and leaving himself on double one in the next leg proved to be no trouble as he made it 14-8.
Wright hit back, winning the next three legs before van Gerwen moved two legs away from victory.
He then scored his ninth 180 but saw his opponent take out 81.
van Gerwen added his tenth maximum and then finished in style, breaking with a ten-dart-leg.
