West Indies skipper Darren Sammy praised team-mate Chris Gayle for a motivational speech that inspired his side to an emphatic nine-wicket win over hapless Bangladesh on Friday.

The Caribbean side bowled the co-hosts out for a paltry 58 in just 18.5 overs -- their lowest ever score in a one-day international -- before cantering to their target in the 13th over of their innings.
