London: Australia paceman Mitchell Starc says he is "yet to be convinced" Kookaburra's pink ball is ready for day/night Test cricket.
The first ever day/night floodlit Test will take place between Australia and New Zealand in Adelaide from November 27, with both governing bodies delivering a positive spin on the initiative.
It is hoped that revised playing times can help reinvigorate the longer format, drawing larger crowds and better television audiences in the evenings.
But Starc, who used a pink ball at the Adelaide Oval during a Sheffield Shield trial, has broken ranks by delivering a less-than-ringing endorsement of Kookaburra's current product.
"It's definitely not a red ball. It doesn't react anything like the red ball, in terms of swing and the hardness of it," he said. "It goes soft pretty quickly.
"I didn't see a huge amount of reverse swing in that game and I don't think it swung from memory too much until the artificial light took over.
