Rain has delayed play in the fifth one-day international between Australia and the West Indies in St Lucia.

Australia, who need to win the match to avoid losing an ODI series to the Windies for the first time in 17 years, were 3-201 in the 39th over when rain started to fall.

Peter Forrest is not out on 37 while Brett Lee, promoted in a pinch-hitting role, is unbeaten on three.

Shane Watson (66) and David Warner (69) earlier set Australia a good platform to post a big total, making 118 at a run-a-ball for the first wicket.
