The most touching moments at the recent world pool championship occurred at its beginning and end, respectively: Efren Reyes, 51, ousted from the group stage, stepping out into the dark Kaoshiung night, and Wu Chia Ching, 16, basking in the glow of his triumph with his grandma wiping his tears away. Who would have thought that after tennis, which now churns out more teenage champions than any other sport except perhaps gymnastics, will be next? Teenage wonders like Wu will become the new masters of the pool universe.
