Silverstone:  Sachin Tendulkar has said Kevin Pietersen's controversial switch-hitting technique should not be banned but cricket's laws needed clarifying.

England batsmen Pietersen sparked a debate last month when, before the bowler reached his delivery stride, he switched to a left-hander's grip and stance then twice hit New Zealand's Scott Styris for six in a one-day international.

The Marylebone Cricket Club (MCC), custodians of the game's laws, quickly convened to discuss the tactic and announced that the innovation conformed to the existing rules.

However, Tendulkar, a batsmen who has always combined a classic technique with wristy innovation, feels the approach needs more thought.

"I think they will have to look at it far more closely than has been done; it changes the laws."

The batsman said the game was seeing the impact of Twenty20.

He added: "The game is changing, it's becoming more and more attacking and players are prepared to take more risks."
