Star forward Robbie Gray booted five goals as Port Adelaide cruised to a 31-point win over Collingwood at the MCG on Saturday.
Port led throughout and put the result beyond doubt with a commanding third quarter in which they booted five straight goals.
The 13.15 (93) to 9.8 (62) victory lifts the Power to third on the ladder and puts Collingwood’s AFL finals hopes in serious jeopardy.
With just five wins and eight losses, the Magpies could fall into the bottom four depending on other results over the weekend.
It was an impressive statement from the Power a fortnight after copping a 70-point pasting from Essendon.
Ruckman Paddy Ryder was in commanding form in his 200th game, ensuring prime movers Ollie Wines, Brad Ebert and Matt White had first use.
The brilliant Gray wreaked havoc throughout, setting the tone with two early goals to put the Power ahead by 21 points at quarter-time.
It was a margin that flattered Collingwood given they had only managed one scoring shot and benefited from the Power missing several of their efforts.
The Magpies badly lacked composure with their ball movement, their constant turnovers allowing the Power to generate repeat forward entries.
Nathan Buckley’s men lifted in the second quarter with Scott Pendlebury leading the way.
The Magpies skipper had 20 disposals and six inside-50s to halftime, while key interceptor Jeremy Howe had 17 touches and six marks.
But Gray booted two goals in quick succession to keep the momentum with the Power.
Up by 17 points at halftime, the Power broke away in the third term, booting five straight goals during a dominant 15-minute stretch.
Darcy Moore (three goals) and Alex Fasolo worked hard for the Magpies, while key defender Tom Clurey impressed for the Power.
