Captain Travis Boak inspired Port Adelaide to a 38-point victory against Richmond on Friday night, dealing a savage blow to the Tigers’ AFL finals hopes.

The Power triumphed 14.10 (94) to 8.8 (56) at a sodden Adelaide Oval to keep their finals ambitions flickering – they’re two wins outside the top eight.

In contrast, Richmond slipped three wins off the top-eight pace with eight minor-round games remaining after meekly surrendering to a Power surge in the second quarter.

Port kicked seven unanswered goals in the second stanza, a spree featuring half-a-dozen goals in 14 minutes – all six came without the Tigers entering their attacking 50-metre arc.

The home side had trailed by six points at quarter-time but, some 25 minutes into the second term, held a 36-point lead before a parochial 37,848-strong home crowd.

Power skipper Boak and the classy Robbie Gray were instrumental in the game-defining burst as Richmond inexplicably slumbered.

Boak finished the game with 26 disposals, 11 tackles and two goals, Gray (24 touches) and Ollie Wines (27 possessions) were influential, while Matthew Broadbent and Chad Wingard both booted two goals.

Richmond rallied briefly in the third term when spearhead Jack Riewoldt kicked two of his four goals to reduce the deficit to 17 points.

But Boak, fittingly, extended Port’s break with a soccered goal from 25 metres out to give his side a 23-point buffer at three quarter-time, a lead which was never threatened.

The Tigers were well served by Riewoldt, Brandon Ellis (33 touches), Anthony Miles (28 possessions), Brett Deledio (30 possessions) and defender Alex Rance.

But trump card Dustin Martin’s 32 possessions had limited impact and captain Trent Cotchin mustered just 14 disposals – he was blanketed by Port’s Kane Mitchell, who collected 24 disposals and kicked a goal.
