ABU DHABI - Australian captain Michael Clarke led from the front and hit a most splendid century to seal the five-match series against Pakistan amid blazing Abu Dhabi heat here Friday. With this decisive victory, Australia now lead the series 3-1 with a match to go at the same venue. Clarke blended aggression with method and thwarted a very potent Pakistan attack that had made early in-roads into the Australian batting line-up. It was Shoaib Akhtar who seemed to discover his venomous touch for once and bowled with speed and accuracy to give Pakistan a faint hope. But Clarke not just stayed defiantly at the crease, he played with aggression against a rejuvenated Shoaib. With Watson (unbeaten 85), the stand-in skipper shared a 197 run stand to see his side through. Shoaib had sent Brad Haddin and Marcus North with just three runs on the board. Shoaib, bent on proving his critics wrong, produced a wicket on the second ball of the innings as Brad Haddin had no clue whatsoever of fast out-swinger giving Kamran Akmal an easy chance. And then he followed it with another express delivery that trapped Marcus North plumb in-front. But Clarke and Watson defied Akhtar's piercing four-over opening spell before easing their way to the modest target set by a struggling Pakistani batting line-up. Clarke produced a contrasting performance to his Pakistan counterpart. Leading on the field with shrewd captaincy, he emerged as a role model for his batsmen. Clarke's footwork and timing was magnificent against both pace and spin. Watson, on the other hand played with caution. This is Australia's first one-day series win since they beat Bangladesh last September, having lost to South Africa -- home and away -- and drawn 2-2 with New Zealand before sealing this series win over Pakistan. Earlier Pakistan middle order buckled under pressure yet again giving the Aussies a fairly easier target of 197. Pakistan failed to consume even their full quota of overs (all out in 48.4 overs). Fast bowler Doug Bollinger was the destroyer-in-chief claiming five scalps with a lot of help from Pakistani batsmen who kept gifting him their wickets. Pakistan had themselves to blame for a repeat of what is now a very familiar middle order collapse. In the crucial do-or-die encounter, Pakistan batsmen failed to curb their self-destructing impulses and eventually the team crashed from 80 for three to 197 all out in 48.4 overs. Doug Bollinger, who returned in place of Ben Hilfenhaus, notched up his maiden wicket when he sent out-of-sorts Salman Butt who edged the ball to Brad Haddin. Bollinger had remained wicketless in his previous appearance and the career breakthrough he desperately needed was handed over to him by a most incompetent batting display from the Pakistanis. Not many had put their money on a Pakistan batting collapse this time. For international sides learn from their mistakes. And Pakistan, when they were supposed to dig it out, just caved in. From team captain Younis Khan to Misbahul Haq, and from Salman Butt to Kamran Akmal, it seemed no one had come to crease with an intent to beat the Australians. Younis Khan was clean bowled by Bracken on a regulation good length delivery. The dismissal spoke volumes of the carelessness reflected in every wicket afterwards. Pakistan were now 12 for 2 and hope was that since all batsmen were due for some runs, a recovery was very much likely. Had it not been for a lucky escape when Misbah apparently nicked the ball and the umpire gave him the benefot of the doubt, Pakistan would have found themselves in even deeper a hole. The Australians insisted he had edged the Bracken delivery, but Aleem Dar thought otherwise. It could well have been 12 for three at this juncture. Misbah then started the repair work and pairing with 17-year-old Ahmed Shehzad (32 not out) built a steady stand taking Pakistan to 80. The pair did commendable work as the Australians bowled a very tight line at this stage. Shahid Afridi hit a run-a-ball 40 with four boundaries and opener Ahmed Shahzad added a slow 43 (just two boundaries in his 81 ball innings). Shahzad was involved in a 36 run fourth wicket partnership with Shoaib Malik also. Earlier, Pakistan replaced in-form paceman Umar Gul and included Shoaib Akhtar in his place.
