Phillip Hughes tried not to tremble during his four-ball duck on Test debut in Johannesburg. For the next week Australian supporters were shaking over the apparently streaky composure of the left-hander who was supposed to be the next Matthew Hayden. The original fears didn't last long and by the end of his first Test series he had showed he could be an unconventional but highly accomplished starter. At 20, Hughes was Australia's youngest debutant since Craig McDermott 25 years earlier, and when he recorded twin centuries in Durban - he brought up his maiden hundred with two sixes - he was the youngest to achieve the feat.
