CHRISTCHURCH: A revitalised West Indies cashed in on a sensational Pakistan batting collapse to notch their first victory of the World Cup by 150 runs at Hagley Oval in Christchurch on Saturday.

The Caribbean cricketers scored 310-6, with 115 runs coming in a swashbuckling final 10 overs involving Lendl Simmons, Andre Russell and Darren Sammy.

Pakistan v West Indies - As it happened

Pakistan in reply crumbled to their second straight defeat when they were all out for 160, failing to recover after the top four wickets fell in the first four overs for just one run, the worst start in one-day international history.

The West Indies, meanwhile, blocked out memories of their shock first up loss to Ireland as six batsmen posted scores of 30 or more.

Denesh Ramdin top scored with 51, Simmons added 50 to go with his first match century, Darren Bravo scored 49, Russell smashed 42 off 17 balls while Marlon Samuels and Sammy chimed in with 38 and 30 respectively.

Bravo was unfortunate not to reach what would have been his 17th ODI half-century when he was forced to retire hurt with a pulled hamstring.

It was the second time he required medical treatment after being dazed earlier in the innings when a powerful throw from Younis Khan hit him on the side of the helmet as he scrambled through for a single.

Pakistan's reply was in trouble when two wicket fell in their first over.

At four down it was serious and at five for 25 in the 11th it was all but over.

When the rout was complete, Jerome Taylor had figures of three for 15 and Russell three for 33 Taylor, Russell and captain Jason Holder had steamed in with an aggression that had been absent from the West Indies armoury of late.
