I think the expression ‘Gentlemen’s game’ is now outdated.
In 17th century when the English elite played it was called ‘gentleman’s game’ which meant no sledging, cheating, bodyline bowling , temper tantrums or excessive appealing. A batsman was expected to walk out the field if he knew he was out even if the umpire decided otherwise.
Over the years we have seen players sledging and on field aggression being considered as passion and competitive spirit. Over the last decade, we have also seen numerous match fixing and tampering incidents, even as recent as last week when Pakistan cricketer Umar Akmal claimed that he was approached for match-fixing and an offer was made to him during the ongoing Global T20 Canada league.
With the game and mannerism evolving over the period, in today’s age, the term ‘Gentleman’s game’ is no longer relevant, I think.
