Usman Khawaja and Travis Head have been named in a 15-man Australia squad for the upcoming Ashes series, after selectors chose to leave the door open to both players in their efforts to make the final XI for next month’s first Test against England. The pair, who have been in a rich vein of form in the Sheffield Shield, are now likely fight it out in a practice match between Australia and an A team starting on 1 December to clinch the No 5 spot in Tim Paine’s side. Otherwise, the team to face England’s tourists at the Gabba on 8 December is settled, with incumbent Test opener Marcus Harris to partner David Warner at the top of the order for the opening two Test matches. At the other end, pace trio Pat Cummins, Josh Hazlewood and Mitchell Starc will only be displaced in the event of injury or fitness concerns, with Jhye Richardson the most likely quick to step in if needed. Australia’s 15-man Test squad: David Warner, Marcus Harris, Marnus Labuschagne, Steve Smith, Travis Head, Usman Khawaja, Cameron Green, Tim Paine (captain), Pat Cummins, Mitchell Starc, Josh Hazlewood, Nathan Lyon, Jhye Richardson, Michael Neser, Mitchell Swepson.
