Jeremy Cameron has continued his pursuit of a rare century with six goals as Geelong pressed their case for an AFL top-two spot with an 88-point thumping of Port Adelaide.

Cameron swelled his season tally to 75 majors as the focal point in the home side’s dominant 23.15 (153) to 9.11 (65) victory at GMHBA Stadium on Sunday.

But while Cameron marched on towards an unlikely ton, it was Jack Martin who took centre stage in the forward line — at least for five minutes and 16 seconds.

In an extraordinary cameo after coming on as the sub, Martin caught fire to kick four majors in just over five minutes, during which time Port Adelaide recorded just three disposals in total.

It lifted the fourth-placed Cats (14-6) to within one win of top sides Adelaide and Collingwood, and two points shy of Brisbane, with three rounds left in the home-and-away campaign.

Cameron, who kicked 11 goals against North Melbourne in Round 20, had four goals to halftime against Port under close attention from Lachie Jones.

The 32-year-old requires another 25 majors in three games plus finals to become the first player since Hawthorn’s Lance Franklin in 2008 to kick 100 in a season.

Max Holmes (35 disposals, two goals), Bailey Smith (30 touches, eight) and Gryran Miers (30 disposals, one goal) also stood out for Geelong.

The only concern for the Cats was Tom Stewart’s high contact on Ollie Wines, which will be scrutinised by the AFL match review officer.

Stewart jumped off the ground in an attempt to smother a Wines handpass and landed on his Power opponent.

But Stewart’s act did not appear malicious and he immediately showed concern for Wines, who was able to play out the game.

Holmes’ running power was on full display from the outset, when he started a play from half-back and ended it by strolling in to kick the opening goal.

Scores were level at quarter-time but the Cats grabbed the contest by the throat when they posted 5.6 to 1.0 in the second term, including three majors to Cameron.

Cats sub Martin replaced ruckman Rhys Stanley in a tactical switch and lit up the third quarter with four goals within a few minutes of entering the fray.

It came as Geelong piled on 9.3 to 1.2 in the third quarter against a Power side that managed just six tackles for the term, before hitting cruise control in the last.

Wines (32 disposals, eight clearancs) and Travis Boak (24 touches, one goal) fought hard for Port, who lost captain Connor Rozee (illness) as a late withdrawal.

Zak Butters was held to just 10 touches and Jase Burgoyne was subbed out in the third quarter with an ankle injury.
