With the Sydney Swans' win in the 2012 Grand Final on 29 September 2012, Pyke became the first Canadian to play in an AFL premiership winning team. When Swans coach John Longmire substituted primary ruckman Shane Mumford, suffering from a sore hamstring, out of the game in the fourth term, Pyke was left to handle the ruck duties alone. He was recognised as playing an important role in the Swans' win. He was credited with 16 disposals, a career high, and three contested marks, more than anyone else on the field except Hawthorn star Lance Franklin, who took four.
