Adelaide: The only Australian bowler who has not made an impact so far, off-spinner Nathan Lyon is aiming for a five-wicket haul against a demoralised India in the ongoing fourth and final Test as he feels the Adelaide Oval pitch is showing "natural variation".
"There's plenty of rough for the spinners so hopefully I will be able to play more of a role tomorrow," said Lyon, who took 3 for 57 during India's second innings here on Friday.
"We're starting to see some natural variation and some spin and the ball is starting to keep low," added the bowler who had taken just two wickets in the series coming into this match.
Nathan Lyon is just wicket away from his first fifer against the Indians.
Australia are just four wickets away from completing a 4-0 series whitewash.
Lyon's first wicket was that of Virender Sehwag, who chose a full toss to hit uppishly into the covers.
"It probably wasn't my best ball. 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 about it," he said.
He also claimed Sachin Tendulkar, caught at forward short leg, but didn't seem overwhelmed by the scalp.
"It's been an absolute privilege to get him out," said Lyon.
This is the first time Lyon has got among the wickets but he stressed he had bowled well throughout the series.
"I've felt I've bowled reasonably okay the whole summer.
It's just good to be able to contribute to hopefully a team's victory," he said.
At one stage, Lyon had nine fielders around the bat during India's second innings.
"To have that many fielders around the bat is something I've never done before. It didn't work but we'll give it a crack another time, hopefully," he said.
Lyon has worked as one of the groundstaff at Adelaide Oval and he said he is enjoying his present stint with the Australian team.
"It's been a different type of fence, you could say right now. I'm enjoying the Test match rather than sitting on the roller watching it. It's been a fantastic experience in front of the home crowd and I've enjoyed every moment of it," he said.
Virat Kohli and Ben Hilfenhaus were involved in a verbal spat on the field on the third day and Friday the latter appeared to have had his revenge by running out the young Indian middle-order batsman.
"What's been said on the field stays on the field as far as I'm concerned. Ben Hilfenhaus' run out was pretty special.
"It set us on a good feeling in the change room right now," said Lyon.
Lyon disagreed with critics that India is an average team.
"I wouldn't say India's an average team. They're full of great cricketers and we still have got a lot of work to do.
Australia are heading in the right direction where we want to get to," he said.
