Sydney, Dec 28 : Sri Lanka has suffered a humiliating innings and 201 runs defeat at the hands of Australia on the third day of the Boxing Day Test match at the MCG, giving the host nation an unassailable 2-0 lead in the series.

 The tourists will count the cost of a bruising encounter at the MCG, which included master batsman Kumar Sangakkara retiring hurt on 27 with an alleged broken finger, the Age reports.

 Needing 304 to make Australia bat a second time, Sri Lanka were bowled out for 103 in 24.2 overs with two players absent hurt, plus Sangakkara who retired hurt, it added.

Australia had resumed on Friday on 8-440 and were dismissed for 460, as Mitchell Johnson was left stranded on 92 not out, eight runs shy of his second Test hundred, the paper reported.

Johnson also claimed 4-63 and 2-16 in a man-of-the-match performance. Sri Lanka lost 3-3 in the opening two overs of their second innings in an embarrassing collapse, the paper said.

 Johnson, who fractured wicketkeeper Prasanna Jayawardene's right thumb in Sri Lanka's first innings, struck Sangakkara on his left index finger on Friday, it added.

In his next over, Johnson hit Dhammika Prasad on the hand and the batsman had a long on-field discussion with medical staff before batting on.

 Prasanna Jaywardene and No. 11 Chanaka Welegedara (hamstring) both didn't bat in Sri Lanka's second innings, the paper concluded. (ANI)
