Good friends van Gerwen and van der Voort are both in Group D following Monday’s draw after the latter sealed one of the four wildcard qualifier places for the Wolverhampton tournament.
Joining them are Kim Huybrechts and Dean Winstanley, with two players progressing from each group to form the last 16.
van Barneveld, who defeated van Gerwen in last year’s final and enjoyed a run to the semi-finals of The Masters in Edinburgh last week, is in Group E with Mervyn King, Tony O’Shea and Ricky Evans.
Former finalist James Wade, who also reached the last four in Edinburgh, will face the Scottish pair of Gary Anderson and Peter Wright as well as Holland’s Wesley Harms.
Group A sees Paul Nicholson pitted against world number one Phil Taylor, Kevin Painter and Stuart Kellett.
The schedule of play for Grand Slam of Darts, which begins on Saturday will be released in due course.
