Stevenson first claimed a PDC Tour Card in 2016, defeating Lee Evans on Day 1 of Q-School. His performances in his first year on the PDC Pro Tour, including his first quarter final in August, resulted in him qualifying for the 2016 Players Championship Finals as the 44th seed, drawing Jelle Klaasen in the first round. He led Klaasen 3-1 and 4-2 but then lost four legs in a row to be defeated.
