Karachi: The ICC has carried out a scrutiny of the Australia and New Zealand World Cup match played in Ahmedabad after Australian openers Shane Watson and Brad Haddin batted slowly in the first 10 overs.

The opening duo scored just 28 in 11 overs and 53 in 15 overs. Though Australia eventually won comfortably but the slow run rate in the first two overs was scrutinised by the ICC anti-corruption and security unit (ASCU).

"They are taking no chances at all and all matches are under the scanner for possible indications that any spot-fixing has taken place," one source said.

Australian team coach Tim Nielsen has defended his openers said that they played slowly according to the situation.

"I thought they played well in game one. Everyone had this perception that they went slowly. But if Zimbabwe were going to be competitive against us, they needed to take early wickets with their spinners. We're playing the way we think is the right way to play," said Nielsen after the match.

With the specter of spot-fixing now looming over international cricket following the ban on three Pakistani players, sources said the ICC ASCU was keeping a vigilant eye on all matches in the World Cup and the slow start by the Australian openers caught their attention.

Pakistan’s Muhammad Asif and Muhammad Aamir were hauled up after being found guilty of deliberately bowling no-balls during the fourth test against England at Lords last year.

Plenty of fuss was also raised over the India and England match after former Australian leg-spinner Shane Warne correctly tweeted seven hours before the start of the match that it would be a tie.

England skipper Andrew Strauss claimed that Warne had shown he was a cricket genius with his correct prediction but others also observed that it was strange how one could predict a tie so early before a match.

Pakistan's former captain Moin Khan said the Warne tweet could have been just a hunch but felt it had raised questions.

Pakistan's test pacer Sohail Tanvir said on Geo Super that the ICC needed to keep a close eye on all matches of the World Cup as it was a mega event and a big attraction for bookmakers in the subcontinent.

Pakistan's former captain Aamir Sohail rued that if any Pakistani or Indian player had made the same tweet about having a tied match lot of hue and cry would have been raised in the western media by now.

"But since this prediction comes from an Australian player it is declared a stroke of genius," he added.
