The three-day invitational event, which will take place from September 16-18 at AFAS Live in Amsterdam, will feature 24 players vying for £300,000 in prize money.
Van Gerwen, a four-time champion, will look to maintain his winning streak on home turf, having recently won the Cazoo Premier League and the Betfred World Matchplay.
Clayton will attempt to defend the championship he won a year ago, while two other past champions, Gerwyn Price and James Wade, will also compete in Amsterdam.
Dimitri Van den Bergh, last year’s runner-up, is among the PDC participants, having won back-to-back World Series victories at the Nordic Darts Masters and Dutch Darts Masters earlier this year.
In the main event, reigning World Champion Peter Wright will compete opposite US Darts Masters winner Michael Smith.
Gary Anderson, the runner-up in the Nordic Darts Masters, Fallon Sherrock, the Women’s World Matchplay champion, and Joe Cullen, the 2022 Masters champion, will be joined in Amsterdam by Australia’s World Cup of Darts champions Damon Heta and Simon Whitlock.
In other news, Dutch Darts Masters runner-up Dirk van Duijvenbode has been invited to September’s showpiece, as has North American Championship winner Leonard Gates.
The PalmerBet Queensland Darts Masters, PalmerBet New South Wales Darts Masters, and TAB NZ Darts Masters will all take place this month as part of the World Series.
Following August’s treble-header Down Under, two more spots will be secured, with an extra eight players scheduled to emerge via the Tour Card Holder Qualifier in Barnsley on Saturday August 6.
Gates first American to play World Series of Darts Finals
Leonard Gates will make his PDC World Darts Championship and Grand Slam of Darts debuts later this year, as well as the World Series of Darts Finals.
Gates was one of the invited players for the AFAS Live in Amsterdam, along with the top World Series players this year, as well as Damon Heta and Simon Whitlock, who won the World Cup of Darts and will play the entire Australia/New Zealand leg anyhow.
He won the North American Championship and advanced to the finals of the US Darts Masters after defeating Fallon Sherrock.
But in doing so, Gates becomes the first American to compete in the tournament with only Jeff Smith previously invited through that route albeit he is from Canada.
