MELBOURNE, Australia (AP) — Mitchell Johnson hit a confident half century to steady Australia to 440-8 and a 284-run lead over Sri Lanka at stumps on Thursday following a mid-order collapse on the second day of the second test.
Johnson followed his four wickets on the first day with an enterprising knock of 73 with six boundaries after Sri Lanka claimed three wickets for just four runs before tea.
Michael Clarke earlier brought up his 22nd test century and first at the Melbourne Cricket Ground after becoming Australia's highest-ever run scorer in a calendar year.
"It's always nice to make runs and even nicer to make a century for Australia and put us in a pretty good position," Clarke said.
Matthew Wade added just one run before becoming Prasad's third victim of the test, caught by Eranga (2-106).
Sri Lanka is likely to start its second innings at least 300 runs behind Australia, and Sri Lanka batting coach Marvan Atapattu said he expects the lineup to show significantly more discipline than in their 156-run first innings effort.
"We've got the capability, we've got the batsmen who are capable enough to make big scores and get us some good partnerships going," Atapattu said. "Hopefully they will put it right in the next innings they bat."
Clarke reached his batting milestone when he got to 56 shortly before lunch. His total for the year is now 1,595, eclipsing recently retired Ricky Ponting's previous record of 1,544 in 2005.
"To me Ricky Ponting is one of the all-time great players Australia's ever had, so to beat Ricky at something is a fantastic achievement, so I'm very proud," Clarke said.
After resuming on the overnight score of 150-3, Clarke made a watchful start before loosening his strokes against a tame Sri Lankan attack. He timed 14 boundaries, showing little sign of the hamstring strain sustained in the first test at Hobart.
One of Clarke's fours came courtesy of an error when Eranga fielded a straight drive off his own delivery only to beat Kumar Sangakkara behind the wicket with a return that carried to the boundary.
Sri Lanka's injury woes worsened on the second morning when paceman Chanaka Welegedara pulled up while running in to bowl to Clarke and limped from the field. He left the grounds for scans on his hamstring.
The visitors lost regular wicketkeeper Prasanna Jayawardene to a fractured right thumb on Wednesday, his place behind the stumps being filled by Sangakkara.
"From a positive side of it, the two catches that (Mahela Jayawardene) held later in the day (to dismiss Clarke and Siddle) will hopefully give him some confidence when he comes out to bat," Atapattu said.
Johnson claimed four wickets Wednesday to help dismiss Sri Lanka in under two sessions. The only highlight of the Sri Lankan innings was a defiant 58 from Sangakkara that included his 10,000th test run.
