Sherrock, the first female finalist in a teelvised PDC event, led 6-3 before the Dutch star roared back to win 11-7.
The three-time world champion overcame Madars Razma 10-4 in his quarter-final earlier in the day before seeing off 超级联赛 winner Jonny Clayton 11-7 in the semi-finals.
Sherrock had reached her first PDC final by producing a thrilling comeback to beat former World Matchplay champion Dimitri Van den Bergh 11-10 in the last four, having faced deficits of 8-2 和 10-6.
Having produced finishes of 101 和 100 in the last two legs of that match, she looked capable of causing another stunning upset as she led 6-3 during the early stages of the final but Van Gerwen reeled off six straight legs to clinch the crown.
“I had to wait a long time to win a trophy,” said Van Gerwen in an emotional on-stage interview.
“Fallon played a phenomenal tournament and I think she played one of her best games in her life in the final and I want to give her all the credit because she made it really difficult.
“I think I deserved it this weekend. I played really well overall but also the crowd has been absolutely phenomenal. It’s been too long since we had crowds like this, especially on a televised tournament, all I can say is thank you very much.
“I’ve been through a really tough period, this means so much to me. I’ve been working really hard on my game and then it finally pays off and I think I played really well over here.”
Sherrock tweeted afterwards: “What a night… absolutely buzzing despite not winning – so proud of myself.
“Congrats to @MvG180 – I can see why your the best now”
