Nathan Lyon has declared he is in the best shape of his career ahead of his 39th birthday, having given up alcohol and taken up an intense fitness regime.
Australia's bowlers again showed off their longevity in Durban on day three, working over South Africa to dismiss them for 284 and set up a 106-run first-innings lead.
As a quartet, Lyon, Pat Cummins, Mitchell Starc and Josh Hazlewood also became the first in history to take 600 wickets in Tests played together on day three.
