World Cup Group D, Jamaica: West Indies 190-2 (38.1 ovs) bt Ireland 183-8 (48 ovs) by 8 wkts (D/L method)
Shiv Chanderpaul said the need to take a good run-rate into the Super 8s had motivated his attacking style in West Indies' emphatic win over Ireland.
Chanderpaul hit four sixes in his fluent century
Chanderpaul hit 10 fours and four sixes in an entertaining unbeaten 102 to help his side top Group D.
"Chasing a decent total and knowing that we were already through I could go out and play my game.
"We had a long discussion on Thursday night and we decided to try and keep up the run-rate," said Chanderpaul.
Skipper Brian Lara praised Chanderpaul's innings and said his side were looking forward to facing Australia in their first Super 8 match on Tuesday.
"We know it's Australia but we have done well against Australia in the recent past and if we play to the best of our ability, it's going to be a hell of a game," he said.
Meanwhile, seamer Daren Powell thanked a quartet of West Indies legends after taking 2-24 in nine overs as the Windies restricted the Irish to 183-8 off 48 overs in a rain-affected match.
"The more I play things are getting easier and I am learning," said Powell.
"Andy Roberts, Courtney Walsh, Ian Bishop and Michael Holding help me. It is up to me to practise what they teach and it is starting to come out now."
