Ricky Ponting went two years without a Test hundred and now the veteran has scored two in three innings in a strong response to speculation his best cricket is behind him.
The 37-year-old hit 137 not out on Tuesday's opening day of the fourth Test against India at Adelaide Oval to steer the home side to 3-335 at stumps, with skipper Michael Clarke scoring an unbeaten 140 on a flat batting track.
The 251-run stand between Clarke and Ponting was the pair's second huge stand of the series after adding 288 in Sydney, where Clarke scored an unbeaten 329.
Ponting's 41st century prompted a spirited waving of the bat to all parts of the ground and places the 162-Test veteran equal with South Africa's Jacques Kallis, trailing only India's Sachin Tendulkar (51).
"It just shows how much it means to him," Australian batting coach Justin Langer told ABC Radio.
