Vettori believes spinners are the key for success Felix Austin | cricket20 Tweet New Zealand skipper Daniel Vettori believes the turning wickets in Guyana will play a key role in the out come of a number of matches at the Twenty20 World Cup. Vettori was delighted that Kiwi seamers Kyle Mills and Ian Butler had recovered form injury but the skipper was expecting himself and Nathan McCullum to play a big role. "I think that we are very confident. You can throw in Kyle Mills who has come back. He has been a very successful bowler for us. Tim Southee’s done a good job and Ian Butler’s come back from injury as well and at times has done a good job for us," said Vettori. "Between the seam bowling department, I think they will be more than adequate but I think that spin bowling is going to play a big part, particularly in the slower grounds in the Caribbean. We are expecting myself and Nathan McCullum to play a big role." "We are hoping to come here and win. I think the guys who played in the 2007 World Cup have good memories from here and really enjoy the ground. It’s a good cricket ground so I think that we are going to get some pretty good games early on." "We’re pretty confident that we’ve got the work under our belt to be ready for the first game against Sri Lanka. It’s hard to know because we haven’t played a game together for a while, so the two practise games are going to be crucial." "It will be the same for every team. These practise games are going to be real insight to how the tournament is going to go."
