If you can't bat at 100 percent, then you are putting pressure on other blokes as well."<br /> <br /> Rob Quiney, who made his Test debut in place of Watson in Brisbane, is expected to bat again at number three, while left-arm paceman <a href="/tags/Mitchell-Starc/post" target="_blank">Mitchell Starc</a> remains the 12th man.<br /> <br /> Clarke said he and the selectors stuck with swing bowler Ben Hilfenhaus because of the improvement they witnessed from the bowling attack in the latter days of the Brisbane Test.<br /> <br /> "I thought the bowlers came back really well. We took 14 South African wickets where they took five of ours," he said.<br /> <br /> "I think we've got a good combination. We've got a good mixture of aggression but also bowlers who can bowl long spells and dry runs up if required out there on that wicket.<br /> <br /> "Generally in Adelaide, you have to bowl quite tight during periods of the game."<br /> <br /> <strong>Australian squad </strong>- Michael Clarke (c), David Warner, Ed Cowan, Rob Quiney, Ricky Ponting, Mike Hussey, Matthew Wade (wk), Peter Siddle, James Pattinson, Nathan Lyon, Ben Hilfenhaus, Mitchell Starc (12th man).
