• Richmond’s recent dominance over Brisbane has continued with the Tigers scoring a comfortable 79-point win in a scrappy affair at the Gabba on Saturday night.

In the battle of the big cats, the Tigers won 21.11 (137) to 8.10 (58) for their eighth-straight victory over the Lions, a record stretching back to round seven, 2009.

Looking to atone for their 82-point loss to North Melbourne last weekend, the Lions never looked in the contest and despite both sides having similar numbers in contested possessions, inside 50s, handballs and clearances, a lack of disposal efficiency and marks inside 50 cost the Lions dearly.

Trent Cotchin (37 disposals) and Bachar Houli (32 disposals) led the way for the Tigers with the Lions assisted by the two Daynes – with Beams and Zorko earning 35 and 27 disposals respectively.

There were seven multiple goal-scorers for the Tigers – with Jack Riewoldt booting four majors – while Zorko booted two goals for the Lions.

Leading by 24 points at halftime, two goals to Riewoldt and one to Nathan Gordon stretched Richmond’s advantage to 41 points midway through the third term – the visitors kicking six unanswered goals since Michael Paparone’s major inside the opening minute of the second term.

Goals to Zorko and debutant Harris Andrews briefly stopped the rot, until two goals inside five minutes to Shaun Grigg extended the Tigers’ lead to 42 points at three-quarter time.

Dustin Martin opened Richmond’s account in the final term before goals to Brisbane’s James Aish and Josh Green were cancelled out by Gordon and Kamdyn McIntosh’s second goals.

The Tigers eventually kicked away with further goals to Riewoldt, Ben Griffiths, Shane Edwards and substitute Sam Lloyd, to see the visitors roar back into the top-eight in front of a crowd of 22,441.

The only sour note for the Tigers was a calf injury to Chris Knights midway through the second quarter.

Meantime, Port Adelaide have recorded their first win of the AFL season after pipping North Melbourne by eight points in an Etihad Stadium epic.

The battle between last year’s two beaten preliminary finalists on Saturday night lived up to its billing.

Lindsay Thomas kicked three goals in the final quarter, including two in the space of 80 seconds, to put the Kangaroos in front late.

With a tick over four minutes remaining, Aaron Young waltzed into an open goal to regain the lead for Port.

Kane Mitchell then stepped up with the match winner as the Power prevailed 17.11 (113) to 16.9 (105).

North coach Brad Scott will be incredibly frustrated by the result, but the way his charges fought back despite a glut of injuries was remarkable.

Last-minute withdrawal Daniel Wells (achilles) joined Nick Dal Santo (hamstring) on the sidelines, robbing the team of two of their cleanest users.

That was nothing compared with a brutal first quarter.

Kangaroos Jack Ziebell and Sam Wright staggered to the rooms after being cleaned up in marking contests.

Wright emerged at quarter time and played out the match.

Ziebell did neither.

The hard nut, who was coughing up blood after his collision with Ollie Wines, was taken to hospital for scans.

Substitute Ben Jacobs entered the fray in the first term, ensuring the visitors would have the advantage when it came to fresh legs.

Little good it did them, with Mason Wood and Drew Petrie kicking goals in the fourth term before Thomas’ show-stopping efforts.

The attrition had looked to be taking its toll late in the first half, when Port piled on three goals in the space of four minutes to grab a 20-point lead at the major break.

The Kangaroos’ desperation was magnificent, especially given the frenzied pressure dished up by the Power.

Port weren’t without their own injury concerns, namely Wines (hand) and Matt White (ankle), while North ruckman Todd Goldstein (finger) was also off the park in the early stages.

Power forward Jay Schulz booted four goals, while Brad Ebert starred in his 150th match.

ok ahead to next Friday’s match against the Demons while the Lions will host the Eagles.
