Can a player playing as a right hand batsman for a few overs switch to his left hand for rest of his innings?
Can a player bowling spin for 2 or 3 balls in a over switch to being a fast bowler in the same over?
What are the general rules about this?
EDIT:
Given two answers are about switch hitting. I apologize for not providing clear informations. Let me explain clearly. Consider a batsman, for example Dhoni comes to crease and faced two or three deliveries and after that can he face the next delivery as a Left handed batsman. He is a right handed batsman by profile. My question is, is it possible for a batsman or bowler to change is playing style i.e.,right to left or left to right during the match?
