Okay, let's get away from the clubs for a bit and discuss an old question.
The anime, at least in the dub, has made passing references to time -
One year passed at the Viridian Gym
Two years passed at the Pichu Bros short
"Years" passed between the first Misty Hoso and the Orange Islands.
This would indicate that, since the Orange Islands occurred after The Battle of the Badge, at least 3 years have passed between the first ep(where Ash was 10) and the beginning of Hoenn. So, in theory, Ash is AT LEAST 13 - he may be older, but we have no evidence to support that.
But is he really? Many are familiar with the Bart Simpson syndrome - where some cartoon characters don't age. On the other hand, some do in fact age.
I think he does age. Why? It seems fairly apparent that Hoenn's Ash looks quite a bit different from Kanto/Johto's Ash. His physical appearance is now more befitting of a teenager, unlike his older one, which is more befitting a ten-year-old.
