Central Age Group championships in Guadalajara, Mexico from July 14 to 22.

National team members were chosen on the basis of achieving triple-A times and their committment to training.

Trevor Ferguson and Craig Roberts will compete in the 18 to 21 age group while Stephen Fahy, Tamika Williams and William Massey will swim in the 15 to 17 division. Stephen Troake, Matthew Hammond, Ronald Cowen and Trevor Nelson have been chosen in the 13-14 age group.

Two swimmers who achieved triple-A times -- Paul Fox and Nuri Latham, both in 11-12 age division -- are not included in the squad for Mexico. But Roberts, Williams, Massey and Troake, although falling short of triple-A times, have been selected.
