Batsman Alex Doolan has been added at the expense of paceman Doug Bollinger in the only change to the 14-man Australian squad attempting to sweep the Ashes series 5-0.

Australia has used the same XI in the four comprehensive wins to date over England, although there is concern over the fitness of Shane Watson and Ryan Harris and that may lead to changes for the fifth Test starting on Friday in Sydney.

“With some players still being assessed by our medical team after four demanding Tests, we have decided to add Alex to ensure we have sufficient cover in our batting line-up,” chief selector John Inverarity said on Monday.

“Alex is a talented player who came under strong consideration for selection ahead of the Ashes series after a string of solid performances in four-day cricket for Tasmania ... and we feel those performances warrant his inclusion in the squad of 14.”

Australia’s bowling coach Craig McDermott predicted Australia would take the same XI into the fifth test, saying he expected to have the same bowling group at the very least and that included Watson.

“I don’t think there will be any drama with Watto,” said McDermott, adding that Australia was on the cusp of only its third sweep of a five-Test Ashes series. “Obviously it’s pretty special times, 4-0 with one to go.”
