First Test, Fatullah, day four (close): Bangladesh 427 & 148 v Australia 269 & 212-4
Ponting strokes one of his seven boundaries away through the covers
Skipper Ricky Ponting stood firm for Australia with an unbeaten 72 as they chased a victory target of 307 in the the first Test against Bangladesh.
They were 212-4 at the end of the fourth day's play but the outcome of the game is still in the balance.
Matthew Hayden (72) shared a second wicket stand of 109 with Ponting, but was run out going for a quick single.
Bangladesh were all out for 148 earlier in the day as Shane Warne and Jason Gillespie took three wickets each.
Gillespie finished with figures of 3-18, while Warne bounced back from rough treatment in the home side's first innings, to claim 3-28.
Resuming on 124-5, Bangladesh lost Khaled Mashud in the second over of play when he offered no stroke to a good delivery from Gillespie and was bowled for a duck.
Mohammad Rafique struck three fours off Warne, but the veteran spinner gained his revenge by winning lbw decisions against Rafique (14) and Enamul Haque off successive deliveries.
Bangladesh only managed to extend their innings by nine overs
Rajin Saleh added only four to his overnight score before he was caught by Hayden off Gillespie for 33 and Warne wrapped the innings up by bowling Mashrafe bin Mortaza for nought.
Facing a difficult run chase, Australia's openers avoided unnecessary risk as they put on 67 for the first wicket either side of tea.
But Mike Hussey's attempt to sweep slow left-armer Haque proved his undoing when he played a fraction too early and under-edged the ball into his stumps, departing for 37.
Hayden and Ponting took the total to 173 before Hayden was beaten by Haque's direct hit at the bowler's end after a 152-ball innings, which included a six and eight fours.
It provided a timely boost for Bangladesh and they were soon celebrating again as left-arm spinner Rafique removed Damien Martyn and Michael Clarke before the close.
Martyn was bowled for seven and Clarke edged a catch to keeper Mashud after making nine.
First innings centurion Adam Gilchrist came to the middle with two overs to survive before the close, and he did so to finish on six not out.
But Australia only have their five bowlers to come and Bangladesh could yet pull off one of the biggest upsets in Test history if they can separate Ponting and Gilchrist early on the final day.
