Nathan Lyon picked up three big wickets at the Adelaide Oval on Friday to help Australia move toward a whitewash over India - a situation he is amazed to be a part of.

A touch over a year ago, Lyon was the groundsman at the Oval as the Aussies crumbled against England during the Ashes. Fast forward to the present and the 24-year-old is mixing it up with the best and dismissing one of the game's greatest players - Sachin Tendulkar.

"It's been a different side of the fence enjoying the Test match rather than sitting on the roller watching it," he said after play on day four.

"It's been a fantastic experience playing in front of the home crowd and I've enjoyed every moment of it."

Lyon has largely been a bystander during the series, with the quicks running riot while he provided solid support. However, he certainly did his bit on Friday as he nipped in with the wickets of Virender Sehwag, Tendulkar and VVS Laxman, helping Australia surge toward victory.

It was Ryan Harris who made the initial breakthrough for the hosts, removing Gautam Gambhir, before Lyon got rid of the dangerous Sehwag as he looked to attack the bowling.

"Sehwag? It was a full toss," he said of the wicket. "Probably wasn't my best ball but I'm not going to call him back, that's for sure.

"Ricky Ponting came up to me just before that ball and said 'do him in the air' so I was pretty happy with it."

The off-spinner then got a wicket he'll certainly remember, that of Tendulkar, caught at short-leg.

"It was an absolute privilege to get him out," admitted Lyon.

"I felt I've bowled reasonably OK all Australian summer. It's just good to be able to contribute, hopefully, to a team victory."

However, Lyon was quick to point out that there is still much work to be done despite Australia needing just four wickets to win, with the Indians still 334 runs behind.

"We've still got another four wickets to go tomorrow," he asserted.

"The job's not done as far as we're concerned.

"We're going to have to turn up and be on our game and hopefully get these four wickets."

The Australians left the field feeling particularly buoyed after Virat Kohli was run out in the penultimate over of the day. Kohli had on Thursday accused the hosts of excessive sledging, pointing a finger at Ben Hilfenhaus in particular. As fate would have it, it was Hilfenhaus' direct-hit that sent him packing.

"There's some good feeling in the change room right now (after the Kohli run out)," added Lyon.

"What's been said on the field stays on the field as far as I'm concerned.

"Ben Hilfenhaus's run out was pretty special."
