Jos Buttler intends to become a "ruthless run-maker" and prove he is not just a one-day specialist.
Buttler struck a sensational 47 from 16 balls in the final one-day international against New Zealand at Trent Bridge last week, smacking three sixes and six fours in a thrillingly powerful and inventive innings.
Before that match his ODI average was just 14.57 and questions were being asked of the Somerset star.
But Buttler, still only 22, believes there is much more to his game though he admits his "lazy attitude" in four-day cricket for Somerset has resulted in being given that tag.
"I had a sit down and looked at my Championship cricket and it's pretty obvious that I've under-performed so far there," he said.
"Maybe using one-day cricket has been bit of an excuse, to say I'm a one-day player and shot maker, those kind of things.
"They were an easy way out and a lazy attitude, so I've sat down and thought of a way to transfer into four-day cricket. I was doing myself an injustice because I'm a better player than that.
"I've been happy with my Championship form so far this year. I want to turn into a ruthless run-maker and I should have scored three hundreds this season.
"I'm excited by my form and look forward to hopefully scoring some more runs when I get back to playing Championship cricket for Somerset.
"I get as much pleasure from making scores in the Championship. It's great to be adaptable and show that to other people who may question that element of my game.
"I know I'm capable of it but haven't always shown it in my three previous years in the Championship, but I'm glad I've shown I can transfer those skills this year."
