Sixteen-year-old Luke Littler will make his World Series debut this month after becoming the youngest player to reach the PDC World Championship final.
Littler will compete in the Bahrain Darts Masters on 18-19 January and the Dutch Darts Masters on 26-27 January.
Last week he was named among the eight players who will feature in Premier League Darts.
England’s Littler lost 7-4 to Luke Humphries in the World Championship final on 3 January.
World number one Humphries will also feature at the Bahrain International Circuit – his first tournament since becoming world champion – and Maaspoort Den Bosch in s-Hertogenbosch.
Former world champions Michael van Gerwen, Peter Wright, Gerwyn Price, Michael Smith and Rob Cross, and World Matchplay champion Nathan Aspinall will compete alongside eight local representatives in both tournaments.
