Stuart Broad produced a devastating display of quick bowling on day two of the deciding Ashes cricket test at the Oval in London which could bring the trophy back to England.
Fifteen wickets fell for 243 runs and by stumps, England led Australia by 230 with seven second-innings wickets in hand and three days to play.
Broad led the way with five for 37 as Australia slumped from 73 without loss to 160 all out before the home team ended the day on 58 for three.
The fast bowler, whose place was in jeopardy before he took six for 91 in the fourth test at Headingley, was a threat from the start of his spell.
Coming on as third change, he quickly dismissed Watson (34) and captain Ricky Ponting (8) before removing Michael Hussey (0), Michael Clarke (3) and Brad Haddin (1).
Off-spinner Graeme Swann also found sufficient turn and bounce from the Pavilion end to chip in with four for 38.
Simon Katich was the only Australian batsman to hang around long, batting for 10 minutes short of three hours for his 50.
England need to win the match to regain the Ashes.
