ABU DHABI, United Arab Emirates: Steven Smith and David Warner hit half centuries on Sunday but Pakistan restricted Australia to 231-9 in the third and final one-day international.
Smith scored a fighting 77 off 105 balls and Warner made 56 off 63 with six fours and a six in a bid to sweep the series after Australia won the first two matches comprehensively.
Out-of-form regular captain Misbah-ul-Haq opted to sit out the final game as Pakistan made four changes.
Pakistan team manager Moin Khan, who is also chief selector, said Misbah wanted to rest but will lead the side in the two test matches against Australia later this month. Shahid Afridi was Pakistan's stand-in captain on Sunday.
Left-arm fast bowler Sohail Tanvir, playing his first match of the series, restricted Australia's batsmen and also got the prized wicket of Smith to finish with 3-40 off 10 overs.
Afridi (2-44) caught and bowled Warner with his legspin as Australia struggled to score freely on the slow wicket of Sheikh Zayed Stadium in the second half of its innings.
Warner provided a 48-run start with Aaron Finch (18) and added 54 more runs with Smith before Pakistan pegged back Australia.
Warner completed his half century with a swept six over midwicket off left-arm spinner Zulfiqar Babar before he lobbed an easy catch back to Afridi.
Fast bowler Mohammad Irfan then removed captain George Bailey without scoring in the next over and Glenn Maxwell (20) was brilliantly caught in the deep by a diving Umar Amin as Australia slipped to 138-4 in the 30th over.
Tanvir bowled to a superb line and length as Pakistan leaked only 9 runs in the second batting powerplay, getting the wickets of struggling Phil Hughes (5) and Brad Haddin (2).
Smith added 40 runs for the seventh wicket stand with James Faulkner (33) before Tanvir first had Smith bowled off a full length delivery and then Amin took his second catch in the deep to dismiss Faulkner.
Pakistan dropped Umar Akmal, injured Wahab Riaz and left-arm spinner Raza Hasan from the team which lost the second match by five wickets at Dubai on Friday.
Middle order batsmen Sohaib Maqsood and Amin, along with left-arm fast bowler Tanvir, got their first chance of the series while Anwar Ali replaced Riaz.
Australia rested key bowlers Mitchell Johnson and Nathan Lyon, who exploited weak Pakistan batting in the previous two matches, and replaced them with Mitchell Starc and Hughes.
