Wellington: Martin Guptill today bludgeoned his way to the record books with the highest individual World Cup knock as New Zealand rode on the opener's swashbuckling unbeaten 237 to crush West Indies by 143 runs and sail into the semifinals of the mega event here.

Batting first in the fourth quarterfinal game, New Zealand notched up an imposing 393 for six, then bowled out West Indies for 250 in 30.3 overs to set up a blockbuster last-four clash with an in-form South Africa at Auckland on March 24.
