AFTER spending the first half of their summer changing winning teams, the Australian cricket selectors have stuck to a losing one for Saturday's fourth Test against West Indies in Adelaide.

Matthew Hayden and Justin Langer retain their places despite double failures in the third Test defeat in Melbourne, and the only change to the 12 is enforced, with uncapped Queensland fast bowler Andrew Bichel replacing injured South Australian Jason Gillespie.

There may be more changes in the final XI, however, with Michael Bevan, 12th man in Melbourne, expected to return. Bevan would owe his selection to his left-arm wrist spin, which has continued to cause the West Indies problems throughout the one day series, and not to his batting - he is regarded as a weak link at number six, and could even drop to seven if Australia are prepared to risk going into the game with only two specialist seamers, and Greg Blewett as back-up.

Their hand may be forced, as Paul Reiffel is still suffering from the hamstring injury which he aggravated on New Year's Day. He will have a fitness test later in the week.

The sense of confusion, if not crisis, surrounding Australian cricket was heightened at the weekend by the sacking of the ACB chief executive Graham Halbish for unspecified reasons.

The West Indies, meanwhile, flew to Melbourne yesterday after a second successive heavy one-day defeat by Pakistan at the SCG, this time in the first of the best-of-three final series worth $100,000.

After an opening stand of 99 between Sherwin Campbell and Junior Murray, they lost seven wickets for 24 in the decisive spell of the match, their innings wrecked by Waqar Younis and Pakistan's latest teenage sensation Shahid Afridi.

Waqar took three for seven in four blistering overs after conceding 29 in his first four, while Alfridi snapped up a low return catch to dismiss Brian Lara for a second ball duck, trapped Jimmy Adams lbw and bowled Campbell with his stunning quicker ball.

The 16-year-old then smashed Curtly Ambrose to all corners of the SCG in a 50-ball half century which set Wasim Akram's team on the way to a four-wicket win with more than 11 overs to spare.

Ambrose clearly suffered a reaction to his hamstring injury, adding to West Indies' selection problems for the fourth Test. Kenny Benjamin has already returned to the Caribbean because of a side injury.
