Spinner Nathan Lyon starred with a match haul of nine wickets as Australia wrapped up the opening Test on Friday with a crushing victory over Sri Lanka before lunch on the third day.
The hosts were bundled out for 113 in their second innings allowing the Australians to seal a 10-wicket victory in their first over back at the crease in Galle.
Lyon, whose five-for helped bowl out Sri Lanka for 212 in the first innings, and fellow spinner Travis Head took four wickets each to send the hosts packing before the morning was over.
It was a huge victory for Australia, who suffered a 3-0 whitewash in Sri Lanka on their last tour in 2016. Sri Lanka suffered a blow before play began when Angelo Mathews was ruled out due to Covid-19, with Oshada Fernando named his replacement.
