New Zealand Paralympic team high performance coach Mal Humm says the success of swimmer Mary Fisher has been a highlight of the Games in London.
Fisher, 19, from Wellington, won a bronze medal in the 50 metre freestyle on Saturday, adding to her silver in the 100 metre race.
Humm says no one really knew what to expect from Fisher at her first Paralympics and there had never been a medal discussion with her.
He says she is racing superbly well and her best event - the 200 metre individual medley - is yet to come.
