England limited-overs wicketkeeper Jos Buttler is determined to become a "ruthless run-maker" in the LV= County Championship and prove his brutal strokeplay can be replicated in the longer form of the game.Buttler struck 47 from 16 balls in the final NatWest Series one-day international against New Zealand at Trent Bridge last week, blasting three sixes and six fours in a thrilling innings.It was undoubtedly the highlight of the 22-year-old's 31 limited-overs internationals to date, with his one-day international average of 14.57 failing to do justice to his promise.However, Buttler is keen to be viewed as more than a one-day specialist, even though he accepts 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," said Buttler, who has scored 426 championship runs this year, including a hundred and two fifties, at an average of 42.6.
"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."England opened their Champions Trophy campaign by beating Australia by 48 runs at Edgbaston on Saturday and resume their title challenge against Sri Lanka at The Oval tomorrow.On Saturday James Anderson returned 3-30 to become England's leading ODI wicket-taker and Buttler believes the squad is armed with a vast array of options in attack."We bowled exceptionally well against Australia. We bowled brilliantly up front, taking early wickets which is key to defending totals," he said."The quality of our bowling attack is brilliant and is spearheaded brilliantly by Jimmy Anderson."With the new fielding restrictions you've seen what's possible when people get in, but with the quality of our bowling attack we're very confident we can take early wickets and put sides under pressure. There are lots of options."The win against Australia was very pleasing. It's great to get off to a winning start, which carried on from the one-day win against New Zealand."
