McEvoy secured his first Australian Olympic Team berth when he finished fifth in the 100m freestyle and sixth in the 200m freestyle at the 2012 nomination trials. He helped qualify the 4x100m and 4 x 200m freestyle relay teams for the finals before Australia went on to finish fourth and fifth respectively.
Four years later in Rio, McEvoy claimed bronze as part of the 4x100m freestyle relay quartet, combining with James Magnussen, Kyle Chalmers and James Roberts.
McEvoy anchored the team home, swimming over the Russians to claim third. His split of 47.00 was the second fastest of all the swimmers, behind only Nathan Adrian of the United States.
In his individual events, McEvoy finished 7th in the 100m freestyle final in 48.12. He finished 11th in his 50m freestyle semi-finals in 21.89.
McEvoy’s brilliance can be traced back to an obsession to be the most efficient as a 7-year-old, sitting pool deck after his training at the Miami pool watching Grant Hackett, and Ian Thorpe when he visited, and learning from their stroke technique.
