GALLE: Australia are on guard for a spin trap when the second and final Test gets underway in Galle on Thursday despite an unassailable lead in the series.

Steve Smith`s men blew the hosts out of the water in the opening contest, winning by an innings and 242 runs the heaviest defeat Sri Lanka has suffered in Test cricket.

That game also played in Galle was on a good batting deck,but the pitchfor the second Test looks a different beast altogether.

`This looks like a very dry surface. Dare say it`s going to turn square,` Smith told reporters on Wednesday.

`We`re not naming a team justyet. We`ll take a call in the morning once we have a better read on the conditions.

Despite already bagging the Warne-Murali Trophy and a place in the World Test Championship final secured, Smith has no intention of taking the foot off the pedal and wants a sweep.

`I thought we played really well last week, controlling the game from the outset. We didn`t do that last time we were here, so it would be a great achievement to win 2-0,` he said.

Sri Lanka are expected to shuffle the pack for the second Test after the last bruising innings loss. Opening batsman Pathum Nissanka is set to return, having recovered froma groin injury, and will replace OshadaFernando.

Off-spinner Ramesh Mendis is likely to come back into the XI in place of Nishan Peiris, whose 41 wicketless overs leaked 189 runs in the first Test.

`Pathum has been declared fit and he will play. But we haven`t finalised our bowling combination yet,` Sri Lanka skipper Dhananjaya de Silva said.

De Silva admitted that Sri Lanka let themselves down with the bat in the opener.

`It wasn`t the typical Galle wicket last time around. It was a disappointing Test match because we should have batted much better than that,` he said. `Too many guys got startsbut failed to kick on. We know where things went wrong, and we`re looking to correct those mistakes.

Sri Lanka will also be playing for one of their finest openers, Dimuth Karunaratne, who is set to retire after what will be his 100th Test appearance.

`Dimuth has been a fabulous leader and an exceptional player,` de Silva said. `He has done some amazing things for the team and, without a doubt, ranks as the best opening batter Sri Lanka has ever produced. We want to give him a fitting farewell.

KONSTAS RELEASED A team spokesperson earlier confirmed Sam Konstas hadbeen released from Australia`s squad ahead of the second Test and will return home to play for New South Wales in their Sheffield Shield match against Queensland in Brisbane.

Nineteen-year-old Konstas, who scored a swashbuckling 60 on his Test debut against India at the Melbourne Cricket Ground on Boxing Day, was dropped for the series-opener.

Travis Head moved up from the middle order to replace Konstas and scored 57 in Australia`s innings and 242-run win.

`Konstas has been released from the Australian squad to play his first match at the Gabba and gain further experience at the venue,` a team spokesperson said on Wednesday. TheGabba will host the second Ashes Test against England in December. Head said he expected Konstas would return to the Test squad for the World Test Championship final against South Africa at Lord`s in June.

`Most likely I`ll go back in the middle order and Sam will open,` Head told Australian media in Galle.
