Aaron Finch is as baffled as anyone when it comes to deciphering why he can be the best Twenty20 batsman on the planet, but never have more than a tenuous grip on a first class spot.

The 27-year-old has spoken repeatedly of his desire to translate his short-form abilities into the longer format – and, after being dropped for a string of low Sheffield Shield scores for Victoria this summer, hopes to have found the keys to unlocking his red ball potential.

“It’s very odd and frustrating,” Finch said in Dhaka ahead of Australia’s World Cup clash with the West Indies on Friday.

“I think in the past I have been very defensive in four-day cricket and not playing any shots really and being conservative.”

The secret, he hopes, is to abandon any conservative mindsets and play with the carefree confidence that has made his T20 and one-day form soar.

That is what has lifted him to the No.1 ranking in T20 cricket, and is why he’s pinpointed as a dangerman whenever his name is raised in opposition team meetings across the planet.

“I think going forward, whether it is at the top of the order or in the middle order, I’ve just got to play my natural game,” he said.

“I feel as though when I am looking to score I am putting pressure on bowlers.

“And regardless of the format I think that is what you aim to do as a batsman.

“I think I probably don’t do that enough and I let them dictate a bit. “So I think this season coming you will see more of an attacking player.”

Finch has signed on to play county cricket with Yorkshire – a role he will take up after a stint with Hyderabad in the Indian Premier League, which follows the World Cup.

“The opportunity to play some quality cricket is going to be huge,” he said.

“Especially some four day cricket, which is going to be valuable.”
