England's change attack inflicted a hapless collapse on Australia, on the way to 145 for seven, in the rain-shortened fifth NatWest Series match at Old Trafford.
James Tredwell took his first home wickets for his country, as the tourists lost four for 12 runs.
Then Ravi Bopara took two for three in seven balls - and despite top-scorer George Bailey's unbeaten 46, Australia's total remained decidedly vulnerable.
They were put in under cloudy skies in this day-night fixture, which got under way at 5.30pm after a long rain delay - and after a watchful start, were a promising 43 for none in the 11th over. Already 3-0 down and with the series lost, they badly needed to consolidate that acceptable start to this 32-overs-per-side match.
David Warner found his range early on, and clubbed a straight six off Broad - only to then have a let-off of his own on 30 when he upper-cut the same bowler high to third-man, where the ball slipped through Samit Patel's hands.
The fielder and England were soon able to breathe a sigh of relief, though, as the drop cost them just those two runs - before off-spinner Tredwell, in his first match since last year's World Cup, struck with his fourth delivery when he had Warner lbw sweeping.
For good measure, Patel and Tredwell then combined to run out number three Peter Forrest - trying to scurry a second for Matthew Wade to long-on but unable to beat the throw from the deep and neat work from the bowler to break the stumps.
Tredwell upped the ante with his next ball, as a frustrated Wade went on the charge and failed to get to an off-break and was stumped for a stodgy 12 from 40 balls. Captain Michael Clarke pushed a faulty single to cover, and was easily short of his ground when Eoin Morgan produced a direct hit.
Then the introduction of Bopara ended an attempted fightback, as Steve Smith edged his first delivery down the leg-side to Craig Kieswetter, and the all-rounder struck with his first attempt in his second over too - David Hussey also caught-behind, trying to steer runs to third-man.
From 86 for six, Bailey and the tail tried to muster a defendable target - and with a six each off Tredwell and then James Anderson from Australia's main contributor, they managed a handy 58 for one wicket in the last 10 overs.
