Australia captain Ricky Ponting feels his team could have won the crucial third Test at Perth - but for India pacer Ishant Sharma.

An awesome spell by Sharma during the hosts second innings led to Australia's defeat, and despite the loss, said he was lucky to be part of a great sporting duel.

"I will always reckon that if I could have got through just one more over in our second innings, then we might still have won," Ponting wrote in his 'Captain's Diary 2008'.

"Tall, lean, ultra-impressive Ishant Sharma, playing just his fourth Test and still eight-and-a-half months short of his 20th birthday, had bowled an awesome spell to me: seven overs when he was fast, aggressive and relentless, where I never felt as if I was truly 'in'," he said.

Ponting lamented that Australia, who had never lost a Test to a team from the sub-continent at the difficult WACA track, went down to India by 72 runs in January this year.

"But even with his heroics, we were 2-117 seeking 413, I was 45 not out, Mike Hussey was 26 not out and I sensed Sharma was about to be taken off. However, Kumble gave his teenage quick one more over. First ball, I pushed forward at a delivery that fizzed through and edged a straightforward catch to Dravid at first slip. From then on, whenever we seemed we might be a chance to reach our imposing target, we faltered," he added.

Ponting, however, said he cherished his duel with the Delhi speedster as it was a great cricketing moment which put the bitterness of Sydney Test behind.
