Doubles rubbers are played on a full singles court (not a doubles court).

  A 1998 born player can play in 10U and 12U.

  A 1999 born player can play in 10U but not in the 12U.

 
  Players must have represented the team in at least one league match prior to the Knock-out stages or have a rating lower/worse than a 9.2 in the 10U. This is not in the rules but will be the same as the 12U rule for this year (i.e. 10U players rated 10.1 or 10.2 can play in the Knockout stages having not played a league match; 10U players that are rated 9.2 or better will need to play at least one league match).
