It was a remarkable effort from Harris, who finished up as the Man of  the Match having only been called into the squad late on match eve as  cover for Peter Siddle, who had a sore back. He began with a wicket in  his first over and returned with three in two overs during the batting  Powerplay when Afridi and Rana Naved-ul-Hasan were giving Pakistan hope  of a famous fightback. 
 They had taken 37 from the first three overs of the field restrictions.  Harris was introduced with 65 needed from 42 balls and promptly yorked  Afridi, who had raced to 40 from 29 balls, and two balls later had Umar  Gul caught skying for a duck. The fifth for Harris came in his next over  when Rana (33) was caught at midwicket and Nathan Hauritz finished  things off in the 48th over with Mohammad Asif caught top-edging. 
 That wrapped up the match and the series and consigned the two matches  in Perth over the next week to dead-rubber status, which will test the  patience of Australian fans for ODIs in a summer featuring ten of them.  It would not have escaped Cricket Australia's notice that the crowd of  15,521 was smaller than the attendance for the domestic Twenty20 final  at the same venue on Saturday, when 17,722 turned up to the Adelaide  Oval. 
 There were late onslaughts in both innings and the hint of a surprise  comeback, but overall the manner of Australia's win won't do a lot for  the cause of the 50-over game. Professional though they were, from the  start of the 20th over to the beginning of the 44th Australia struck  only four boundaries and added 114 runs. It's precisely these middle  overs that the Twenty20 format eliminates. 
 Clarke's first four didn't come until he had 56 runs on the board as he  gladly pushed singles and twos to the defensive field. Despite the lack  of pizzazz, it was the sort of innings his team was hoping for and he  built three important partnerships, 85 runs with Marsh, 55 with Cameron  White and 80 with Hussey. 
 The fun came in the last ten overs when, led by Clarke and Hussey,  Australia added 95, helped by sloppy work from Pakistan, who had earlier  missed run-outs and dropped Clarke on 32. The 48th over, bowled by Gul,  featured three consecutive no-balls - an overstep, a full toss above  waist height, and a delivery with too many fielders outside the circle.  The over took nine balls and cost 23 runs. 
 Clarke (80) and Hussey, who hit 49 from 28 balls, both fell to Gul in  the 50th over but by then they'd done their job. The platform had been  built by Marsh and Shane Watson, who combine for a 63-run opening stand  that ended when Watson was bowled trying to slog a wonderful offcutter  from Asif. 
 Marsh went on to pass fifty for the seventh time in one-day  internationals and looked set for his second hundred when he was stumped  for 83, lured at a wide, spinning ball from Saeed Ajmal. Ajmal was the  hardest of Pakistan's bowlers to get away, with 1 for 41 from his ten  overs, but they'd dropped their other spinner Shoaib Malik and Australia  handled the fast men with ease. 
 It wasn't quite the same for Pakistan, even though Australia's three  main fast seamers entered the game with a combined 14 matches of  experience. Harris kicked things off with Kamran Akmal lbw for 1 in the  second over in a decision that, while tight and probably striking him a  fraction outside off, was not a howler from Asoka de Silva.  
 His next call was. Salman Butt loomed as the man most likely to anchor  Pakistan's innings and had 34 when he was sent packing by de Silva, who  upheld Clint McKay's appeal despite the ball pitching a long way outside  leg stump and sailing well over the top of the bails, according  to Hawkeye's prediction. 
 There was no doubt about the second of McKay's three wickets. Younis  Khan, who had taken 20 balls to get off the mark, was surprised by a  sharp rising bouncer that took the top edge and was snaffled by Haddin.  Mohammad Yousuf followed when he chopped on to Watson and it took an  85-run stand from Umar Akmal (59) and Fawad Alam (33) to give Pakistan a  sniff. 
 Afridi and Rana gave them more than that before Harris spoilt their fun.  It will be a brave selection panel to leave Harris, a cover player in  Adelaide, on the sidelines for the next two games.
