Man of the match Abdul Razzaq was 63 not out and took 4-53 to lead Pakistan to a three-wicket win over Australia in their VB Series match today at the WACA ground.Yousuf Youhana was top scorer for Pakistan with 72 runs as the winners moved ahead of the West Indies and into second place in the tri-series standings.The winner of the Pakistan-West Indies match on Tuesday in Perth will meet Australia in the best-of-three finals series starting next Friday in Melbourne.Australia reached 265 from its 50 overs but Razzaq, Youhana and a late burst from Shahid Afridi — 30 off 13 balls — steered Pakistan to 268-7 with 16 balls to spare.Earlier, Michael Clarke made a defiant half-century for Australia. Hot weather and a hard, fast pitch at the WACA ground favored batsmen, and Australia captain Ricky Ponting set out to take advantage of those conditions when he won the toss and elected to bat first.Australia scored slowly and lost wickets regularly against an accurate Pakistan attack. Australia was only 196-7 after 40, but Clarke generated some impetus in the latter part of the innings, reaching 75 from 75 balls.Clarke came to the crease when Australia was 111-3 in the 22nd over and survived the remainder of the innings. Earlier, Adam Gilchrist made a strong return to the squad after an extended absence through injury, scoring 47 from 46 balls with seven boundaries.Gilchrist did most of the early scoring as Australia reached 48-1 after 10 overs. Hayden failed again, making only six from 16 balls, while Ponting made 29 and Damien Martyn 24.Brief scores: Australia: 265 (A Gilchrist 47, M Clarke n.o. 76; A Razzaq 4/53) lost to Pakistan: 268/7 (Y Youhana 72, A Razzaq n.o. 63, S Afridi 30; G McGrath 2/27, Symonds 2/65).
