Rotation will be the watch out word as Team India prepare to take on Australia in the fourth match of the ongoing CB series on Sunday in Adelaide.

However, wether Sachin Tendulkar will be rested for tomorrow's match as per the rotation policy still remains unclear.

When grilled about the team's rotation policy in the pre-match press conference, Ashwin could not come up with a definitive answer.

"How do I know about the team's selection policy," Ashwin said.

India's batting line-up for Sunday's tri-series match against Australia is again likely to have a change at the top to allow youngsters in the middle order, especially Rohit Sharma, to get a hit in the centre.

The rotation policy, by logic, should now call for Sachin Tendulkar to be put on bench but indications are that the veteran would be a part of the playing eleven, implying either Virender Sehwag or Gautam Gambhir would sit out.

Media manager, GS Walia made it clear that the team's priority is to qualify for the finals of the triangular series and not rotation policy.

"Rotation doesn't mean that we have to adhere to it without seeing the interest of the team," Walia told reporters on the eve of the match.

"The first priority is to qualify for the finals," he added.

Skipper Mahendra Singh Dhoni may like to carry on with the rotation policy but the question is will the team management ask the iconic batsman to sit out of the clash against Australia at the Adelaide Oval to accommodate Sharma.

With a win against the winless Sri Lankans, India are second in the points table. The unbeaten Australians are top of the heap after two successive wins.

India have a selection issue on hand as there is a dilemma on whether to go with two spinners or two medium pacers in the match.

Leg-spinner Rahul Sharma, who pulled out of Perth's game last Friday because of a split webbing, turned his arm over in the nets on Saturday and if he is fit, skipper Mahendra Singh Dhoni would be loath to leave him out.

The tall youngster gains exceptional bounce on his leg-spinners and is very difficult to get away.

While Sharma cooled his heels in Perth, off-spinner Ravichandran Ashwin grabbed his chances with both hands and was man of the match for his 3/32 and unbeaten 30 runs with the bat.

Ashwin can't be dropped now and if Sharma also is brought in, then either Zaheer Khan or Vinay Kumar would miss out in the playing eleven.

Australia, on the other hand, will blood a youngster in the match. Queenslander Peter Forrest or Western Australia's Mitchell Marsh could get a call up to fill in the place left vacant by Michael Hussey.

Australia have pulled out Hussey and pacer Ben Hilfenhaus from the squad which gives an opportunity to either Forrest or Marsh to come into the picture.

Marsh has already played a one-day international, a game against South Africa at Centurion last year, but is in serious reckoning this year with some powerful knocks in the Big Bash league in his bag.

The 20-year-old youngster from a sporting family - his father Geoff Marsh and elder brother Shaun Marsh have both represented Australia - Mitchell also bowls his medium-pacers in high 130s and is an excellent all-round fielder.

Forrest, who originally hails from New South Wales, has had a windfall since he moved to Queensland last year. In six Shield matches, the 26-year-old middle order bat struck three centuries. Skipper Michael Clarke has already spoken in glowing terms about the youngster.

Australia can afford to tinker with the squad as they presently lead the table in the triangular series with nine points from two matches. India are second with four points while Sri Lanka it yet to open account from as many matches.

India have always found it difficult to pin down Australia in the latter's backyard and given how the summer has panned out, it would be doubly so difficult for the visitors.

Australia are not without their own worry. They still are searching for a stable start at the top. Veteran Ricky Ponting has been a failure in both the matches thus far.

Opener David Warner has thumped a stroke or two and then left the scene. Fortunately for them, the work in the field has usually been overwhelming for the opponents.

The last two days in the city have seen intermittent rains and it's generally been cool, unlike in the Test last month when the temperature hovered in the mid-30s all through.
