The most common forms of dismissal are bowled, when the bowler hits the stumps directly with the ball and dislodges the bails; leg before wicket (lbw), when the batsman prevents the ball from hitting the stumps with his body instead of his bat; and caught, when the batsman hits the ball into the air and it is intercepted by a fielder before touching the ground.
Not just that, the other players from both the teams look uncomfortable playing with him. The opposite bowlers don’t know whether to bowl seriously at him, or try to bowl dot balls wide of the stumps (that’s what the leggie ended up doing) while the other batsmen in his team are trying to hog the strike so they can avoid playing those dot balls. They even tried quick runs which he obviously can’t take and those dot balls probably cost them a lot in the last two overs. Seriously, who even allowed him to play at this level?
