Shane Warne believes captains determine spin bowling's future and they must be educated with how to use the slower options.

Speaking at the Cricket Australia Spin Summit in Brisbane, Warne said that the circumstances in which young spin bowlers were used are crucial to their development. He said it was important that they were used as a tactical option rather than a means of last resort.

"One of the things is educating captains around Australian how to use a spinner," said the Australian bowling legend.

Spin not an escape route

"They are not an afterthought. They don't bowl after all the quicks have finished, and then say, you have a bowl because no-one can get a wicket.

"You can bring them on early and take a wicket. That's imagination as a captain. Hopefully, the captains around Australia, we can educate those guys. We can educate the coaches to get the information to the spinner on how to have the right tactics, what to do.

"We're very lucky in Australia that we have a wealth of ex-spin bowlers that are ready to help."

Warne said the use of spinners as a defensive bowling option could be counter-productive to their development. He wants Australia's future spin bowlers to be as attacking as he was when he was playing and he said that Australian spin ranks needed depth to create competition.

Attack-based spin

"Depends what captain you played under whether you were used as an attacking option or not. The bottom line is that we want our spin bowlers to be attacking, we want to be playing at least one spinner in each domestic team," he said.

"We want to create these spin bowlers that the national selector have something to choose from, it's not just, 'Who do we choose?', 'Do we pick the best of a bad bunch? What we want is to give them options. We don't want to be in a situation where it's 'he'll do'."

Warne said it was important to develop spinners to perform at their best in different conditions, and to have several spinners competing for the one spot.

"There's different conditions, India, South Africa, Australia they are all different. There are different spinners who are suited to different conditions better but hopefully we would have one or spinners who are vying for one spot that can play in any conditions," he said.

And he backed the selection of New South Wales spinner Nathan Hauritz for the upcoming Ashes series, saying he had the potential to play a major role.

"I think with Nathan Hauritz at the Ashes, I think he's going to play a big role. He's improved out of sight. I think he's bowling exceptionally well," he concluded.
