MELBOURNE — Australia's second Test thrashing of an injury-ravaged Sri Lanka provided some consolation after a stinging 1-0 loss in the home series to South Africa, but has left the team with much to ponder ahead of the dead rubber Test in Sydney next week. Australia heads into the final match of the series with an unassailable 2-0 lead, but the innings victory in Melbourne was soured with ongoing injury clouds over skipper Michael Clarke and vice captain Shane Watson. The fitness concerns have added further ammunition to critics of the team's player management, with selectors and fitness staff already under fire for a controversial rotation policy that saw injury-free seamer Mitchell Starc rested for Melbourne for fear he might break down. Both Watson and Clarke played despite bringing injuries into the Melbourne Test, leaving selectors open to accusations of double standards. While Clarke scored a glittering 106 and Watson a solid 83 to help set up victory, the wash-out from Melbourne will do little to quell the grumbling. All-rounder Watson broke down with a calf strain after bowling on day one and will miss the Sydney Test, while Clarke remains in doubt as he continues his battle to recover from a hamstring strain. The support staff's best intentions have not stopped young pacemen James Pattinson and Pat Cummins from breaking down among a raft of injuries, while 22-year-old Starc's Melbourne omission left the bowler tweeting that he was “shattered” by the decision. Selectors have also backed themselves into a corner by promising Starc would play at the Sydney Cricket Ground, meaning either one of Mitchell Johnson, Peter Siddle or Jackson Bird must miss out on a wicket traditionally conducive to spin. Watson's injury has opened the door for uncapped Glenn Maxwell, but re-opened a can of worms as to what to do with the barrel-chested vice captain. — Reuters
