SYDNEY:- A November 2020 home fixture against Afghanistan looms as a likely rehearsal for four-day Test matches in Australia, as the Cricket Australia chief executive Kevin Roberts declared the governing body and other nations needed to be more open to the concept beyond the end of the first two editions of the World Test Championship from 2019 to 2023. Roberts, who replaced James Sutherland as CA chief executive in October, said the combination of audience sizes, easing of scheduling squeezes, and Test cricket’s own history of variable playing hours made the four-day question a serious one for all administrators.
