Australian white-ball captain Aaron Finch has urged Cricket Australia to implement a decision review system in the Big Bash League but while Kevin Roberts says he is open to the idea, the CA chief has ruled out bringing in the technology this season.

Calls for DRS to be introduced for the BBL were renewed on Tuesday night after Sydney Thunder batsman Usman Khawaja got the benefit of a dubious decision in which he survived an lbw appeal in the season-opener against Brisbane Heat at the Gabba.

DRS is used in all international cricket formats but has never been used in the BBL, with the cost of using the technology around the country and the delay in matches caused by reviews among the reasons attributed to the system not being introduced across the first eight seasons of the domestic Twenty20 league.

However Tuesday night's match also marked the introduction of the 90-second strategic timeout during Big Bash games, which affords extra advertising time for host broadcaster Channel Seven while stretching out matches by an extra few minutes.
