A tenacious Richmond upset Port Adelaide by 33 points to wreck Sunday’s AFL retirement party of Power stalwart Kane Cornes.

The Tigers, with Jack Riewoldt kicking four goals, climbed into the top eight with a stirring 11.10 (76) to 5.13 (43) win at Adelaide Oval.

Richmond squared their win-loss record at four-all while Port, tipped pre-season as a premiership fancy, slip to a precarious three wins and five losses.

The Power were unable to send off in style their stalwart Cornes, who retired after playing his 300th AFL game.

Both clubs suffered key injuries with Richmond ruckman Ty Vickery hurting a knee and Port backman Jackson Trengove damaging an ankle.

The duo were substituted from a clash in which a fast-starting Richmond were never headed before 45,268 spectators.

Riewoldt was superb while Brett Deledio (28 disposals), Brandon Ellis (30 possessions), Shaun Grigg, Dustin Martin and Anthony Miles were prominent.

Port struggled for clear winners – captain Travis Boak gathered a game-high 32 disposals, midfielder Ollie Wines (24 touches) was busy and small forwards Angus Monfries and Chad Wingard each kicked two goals.

But Port were overwhelmed by the Tigers, who set the tone by holding their hosts goalless in the opening term.

Port were again held at bay in the second stanza with Riewoldt kicking two goals in two minutes and the Tigers crafting a 23-point halftime lead, 7.5 to 3.6.

Scoring dried in a tight third term – the Tigers didn’t register anything at all and Port just 1.4, reducing their deficit to 13 points at the last change.

But Richmond snuffed out any hope of a late charge by the home side, kicking the initial two goals of the quarter en route to victory.
