The age groups are 8-9 years old, 10-11 years old, 12-13 years old and 14-16 years old. So the youngest player should be 8 years old. Also note they must play in the age bracket they are turning this year. ie. 8, 9 this year to play in the 8-9s, 12 or 13 to play in the 12-13s etc. You can form a team in the 8-9s age group consiting of any mix of 8 or 9 year olds. Any person found to be playing over aged, their team will forfeit all points for the season.
