Cricket's controversial review system is once again doing the Black Caps no favours early on in the second test against Australia in Perth.
Australia were well in control just before tea on the opening day at the WACA, with opener David Warner and Usman Khawaja in commanding form at the crease.
But the Black Caps will feel that both should be back in the sheds following a couple of unlucky umpiring decisions.
Trent Boult looked to have trapped Warner lbw just after lunch, but umpire Nigel Llong ruled it not out. The Kiwis opted to review the decision, with the ball tracking technology showing it was hitting the top of the middle stump.
However, the DRS rules dictate the tracking must show at least 50 per cent of the ball hitting the stump for the decision to be overturned, and the challenge was turned down.
