It was a third day of dramatic collapses in the third Test at the WACA Friday with Australia slumping to 137 for eight in its second innings after bowling West Indies out for 312. The Windies looked out of the game when dismissed just after lunch, 208 runs behind the host. But Sulieman Benn (two for 26), Dwayne Bravo (three for 34) and Kemar Roach (one for 18) bowled them back into the match, with Australia losing seven wickets for 68 runs to establish a lead of 345 at stumps. The West Indies started the day on 214 for two in reply to Australia's 520 for seven declared, and had made steady progress to be 280 for four at lunch. But that was when the drama began. The Windies lost six for 32 after the first interval to miss the follow-on target. The tourists lost their last four wickets for just two runs off 10 balls, as Doug Bollinger (five for 70) and Nathan Hauritz (three for 66) did the damage. Australia elected to bat again and was moving on solidly with Michael Clarke and Shane Watson together after Simon Katich was out early for 10. But the host then lost six wickets for 59 runs to slip to 125 for seven, with Ricky Ponting coming in at number nine due to a tendon injury in his elbow. Roach immediately came on to pepper him with short balls and after he got one hook shot away, he fended one straight to short leg to be out for two and leave Australia on 134 for eight. Hauritz and debutant Clint McKay added three more before the close. Benn suspended, Aussies fined West Indies spinner Sulieman Benn has been suspended for two ODIs, while Australia's Brad Haddin and Mitchell Johnson have been fined over a heated on-field altercation during the third cricket Test. The International Cricket Council said Friday that Benn will miss the opening two limited-overs matches against Australia in Melbourne on Feb. 7 and Adelaide on Feb. 9. Haddin and Johnson have been fined 25 percent and 10 percent of their respective match fees for their part in the altercation. The incident took place during Australia's first innings, when bowler Benn collided with non-striker Johnson while trying to field a ball. Two balls later, Haddin became involved when he pointed his bat at the bowler, who had shaped to throw at the striker's end with the batsman standing in his crease. The three players became embroiled in a heated altercation at the end of the over, with Benn pointing at Haddin over Johnson's shoulder. Benn pleaded not guilty to his level two offense but match referee Chris Broad found him guilty at a hearing following the second day's play in Perth.
