Fremantle continued its late finals push and dealt Richmond's fading September ambitions another blow with a 27-point AFL win at Subiaco Oval.

In a tight struggle the Dockers did enough in the final term to win 13.15 (93) to 9.12 (66) and snare a valuable four points.

The win was Fremantle's fifth on the trot, equalling a club record, and lifts the Dockers to a 10-9 record only a month after their season appeared over.

They still have an incredibly tough run home however, facing West Coast and St Kilda at Subiaco Oval, and Port Adelaide away.

The Tigers (9-10) have now lost eight of their past 10 games and face the red-hot Western Bulldogs next week with their finals hopes in serious doubt.

Two late Kayne Pettifer goals reduced the margin to 10 points in the final term, but the Dockers steadied to ensure the victory.

Josh Carr kicked three goals to carry on his strong recent form for the Dockers, while Richmond's Brett Deledio's stocks continued to rise after an outstanding performance.

The main cause for concern for the home side was a moment of madness from maligned midfielder Des Headland that was instantly reported by umpire Matt Stevic.

Headland hit Mark Coughlan high and late after a mark to spark a melee and the Dockers midfielder then quickly followed up with a wild punch at the head of former Tigers skipper Wayne Campbell.

Both sides will likely be out of pocket after the melee is reviewed, but it is Headland's moment of stupidity that threatens to disrupt Fremantle's late finals push.
