most common form of extras scored in Test cricket. The average number of leg byes scored in a Test match is about 20; in a 50 over game it is about 10. The most leg byes in a single test innings is 35, conceded by England against South Africa in the Proteas' tour of England, on 1 August 2008. Scoring notation The conventional notation for a single leg bye is a triangle with a point at the base and horizontal edge at the top (an inverted bye symbol). If more than one leg bye is taken the number scored is written within the triangle - in practice it is easier to write the number down and then draw the triangle around it. Validity Prior to his retirement from Test cricket Australian captain Steve Waugh called for leg byes to be removed from the sport, commenting: "I don't think you should get runs when you miss the ball." Umpire's signal Umpires signal a leg bye with a hand touching their raised knee. References Cricket terminology Scoring (cricket) Cricket laws and regulations
