Richmond resisted as long as it could, but with so much on the line for Port Adelaide to climb into the top eight, the Power lifted to a 41-point win.

The Tigers closed within one point midway through the third quarter before Port powered away to the 16.20 (116) to 11.9 (75) win at Adelaide Oval on Saturday night.

The lead changed eleven times through the first half, but the Power lifted the pressure in the third term.

With the game still in the balance and just a 10-point lead at the final change, Port pulled away in the fourth quarter.

Port captain Connor Rozee (24 touches) also booted two majors, Brownlow medallist Ollie Wines (32 possessions) and ex-skipper Travis Boak (24, one goal) were prominent, while Jordon Sweet ruled the rucks.

The Tigers were brilliantly served by Daniel Rioli, who gathered 28 disposals and kicked two goals, and Rhyan Mansell slotted three goals.

Stalwart Dion Prestia (24 disposals, one goal), on-baller Jacob Hopper (25) and Jayden Short (23) were also busy, but the Tigers remain on the bottom with two wins.

Richmond veteran Prestia kicked the opening goal as the visitors started strongly but failed to cash in on the scoreboard.

The Tigers at one stage had 16 to six inside 50s but a late Willie Rioli goal gave Port, propelled by 21 disposals between ex-captains Wines and Boak, a 4.2 to 3.3 edge at quarter-time.

The teams then traded goals in the second stanza as the Power gained ascendancy but, like their opponents in the first term, failed to fully convert.

Port kicked 3.6 to 3.3 for the quarter and held an eight-point break at half-time despite the visitors boasting the two leading ball-winners to the break, Rioli (21 touches) and Prestia (18).

In the third term, Richmond snuck within one point when Rhyan Mansell slotted his third goal with a superb snap from a tight angle.

But the Power rallied with three goals in less than three minutes to create a 20-point advantage with five minutes remaining in the quarter.

The Tigers again rallied with two late goals and a Kamdyn McIntosh strike reduced their deficit to 10 points at three-quarter time.

In the last term, Port forward Dixon converted a set-shot early to sap Richmond's resistance - the Power kicking 4.8 to one point in the fourth quarter.
