Australia were all out for 460 in their first innings early on the third day to lead Sri Lanka by 304 runs in the second Test in Melbourne on Friday. Mitchell Johnson was left stranded short of his second Test century on 92 not out off 150 balls, with Sri Lanka facing the task of wiping out the huge innings deficit to make Australia bat again. Dhammika Prasad finished with three for 106 and Shaminda Eranga grabbed three for 109. Shane Watson was unlikely to bowl in Sri Lanka\'s second innings after a fresh calf muscle injury suffered bowling on Wednesday\'s opening day of the Test.
