Australia claimed four wickets to move closer to victory on the last day of the first Ashes test as England went to lunch Monday on 85-4 in its second innings and still needing an unlikely 313 more runs to win.
Offspinner Nathan Lyon proved the threat that England feared and has 3-31 in 11 overs.
Jos Buttler (1 not out) and Ben Stokes (0 not out) are at the crease. Roy was out for 28 after sharing a 41-run partnership with Root and England on 60-2.
Bancroft caught Joe Denly (11) after Lyon struck again to leave England 80-3.
Earlier, Rory Burns (11) was the first man out — caught by Lyon off Pat Cummins — when England had added only six runs after resuming on 13-0.
Australia declared at 487-7 in its second innings on Sunday. Steve Smith and Matthew Wade scored centuries as the hosts were set a target of 398.
