A Yousuf Youhana century and a late West Indies batting collapse combined to give Pakistan a place in the tri-series one-day cricket final against Australia.

Man of the match Yousuf's 105 from just 100 balls helped Pakistan reach an impressive 8-307 from its 50 overs at the WACA, with the West Indies managing 277 from 48.1 overs in reply.

Pakistan, which inflicted the first defeat on Australia in the competition at the WACA on Sunday, will now meet the world champions in a best-of-three decider starting at the MCG on Friday.

Yousuf produced a 134-run fourth-wicket stand with captain Inzamam-ul-Haq (74 from 67) as Pakistan recorded the second highest one-day total ever at the WACA.

The all-time mark is 309 by the West Indies against Sri Lanka in 1984, while only five teams have bettered the 300-run mark in 56 one-dayers in Perth.

The West Indies were on track to nudge the 21-year-old record when Ramnaresh Sarwan (87) and Shivnarine Chanderpaul (58) took the score to 3-194 after 32.5 overs.

But they lost 7-83 to spoil their finals hopes.

Their lower order attempted to reproduce last year's ICC Champions Trophy final heroics, when Courtney Browne and Ian Bradshaw compiled a 71-run ninth wicket stand for an unlikely win over England at The Oval.

The pair did come together at 7-257 still requiring 51 runs for victory, but a fourth-ball duck by Bradshaw gave Pakistan the last laugh.

Brian Lara's men end the triangular competition with just one win and one no result from six matches.
