Australia take on Sri Lanka in the sixth match of the tri-nation ODI cricket series at Sydney today. In the last match between the two teams at Perth, host Australia had defeated Sri Lanka by 5 runs. MS Dhoni led Team India is currently leading the table with 10 points from 4 games, while Australia is second with 9 points from 3 games. Sri Lanka is third with just 2 points from 3 games.The hosts will face Sri Lanka on the back of a narrow four-wicket loss to India in their previous match. The biggest concern to emerge from the defeat was the top-order failure. On the bowling front, veteran pace spearhead Brett Lee is expected to be back to lead the attack after making a stunning early recovery from a toe injury .Sri Lanka, on the other hand, have batting problems of their own to sort out.The aggressive Tillakaratne Dilshan'sbat has been uncharacteristically quiet and Kumar Sangakkara is also due to play an innings of substance.Dinesh Chandimal and Mahela Jayawardene though batted well in the match against India but the lack of a concerted effort means that bowlers have been far too often left too little to play with.The bowlers, on their part, have done a decent job. This was evident from the way they stifled a formidable Indianbatting line-up in the previous match.
