The fog of despair at Phillip Hughes' death has finally lifted for his great mate, South Australian batsman Tom Cooper.

Cooper was batting with his housemate Hughes when the former Australian opener was stuck by a ball in a Sheffield Shield match in November 2014. Hughes died three days later.

SA coach Jamie Siddons believes it's taken Cooper until now to deal with his grief and again become a linchpin in the Redbacks' Shield side, which hosts Tasmania from Friday.
