Cricket Australia won't reopen 2018 ball-tampering probe

Cricket Australia chief executive Todd Greenberg has ruled out a further investigation into the 2018 ball-tampering affair in South Africa. Former opener David Warner backs Usman Khawaja, who says the team began tampering in the second Test in Gqeberha, not the third Test in Cape Town where they were caught. Khawaja's autobiography claims the whole squad knew of the sandpaper plot. Mitchell Starc denies advance knowledge. The original inquiry found only Steve Smith, David Warner and Cameron Bancroft culpable, and their penalties followed.
