New Zealand pace spearhead Trent Boult has attributed the low-scoring thrillers at the ongoing World Cup to the "glossier" Kookaburra balls which offers more swing, making the contest between bat and ball even.

"The balls are actually different for this tournament. They've got a different gloss on them, they're painted differently, so there's definitely been a little bit more swing," said Boult, who took his 150th ODI wicket against Bangladesh at The Oval on Wednesday.
