The crack pairing have been drawn in Group D for the two-day event where the top two from each of Saturday's four pools goes forward to the knockouts on Sunday.
Joining co-favourites Sanders and Price in their group will be the all-Vale Rec combination of Nigel Collins and Rose Ogier, the Guernsey Bowling Club partnership of Francis Tardif and Jackie Le Tissier, and one other wild card.
Group A features the hotly-favoured pair of Matt Le Ber and Gary Pitschou who have 11 island singles title between them, while the new pairing of Chris Dyer and Micky Ogier find themselves in Group C where a potential quarter-final clash with Sanders and Price is just possible.
With £500 going to the winners and Sanders and Price aboard, a feat of bowls is promised, said Bowls Guernsey president Rob Batiste.
'The film Blackball was based on Griff's controversial and enigmatic early career and paired with John, who has won the Welsh national title 10 times, the world indoor trophy once and a Commonwealth Games silver medal, they should provide the local bowls community with plenty of entertainment.'
