The Sydney Swans have increased West Coast's road woes with a 39-point pounding of the Eagles at the SCG.

In a tight slog, the Swans had the answers to every Eagles challenge and kicked the final six goals to run out 12.16 (88) to 7.7 (49) victors.

Gun midfielders Luke Parker, Tom Mitchell, Dan Hannebery and Josh Kennedy led the way, while youngster Tom Papley was influential throughout and Ted Richards was one of the best on the ground.

Lance Franklin booted 2.5, while co-captain Jarrad McVeigh also bobbed up with two goals.

Andrew Gaff, Matt Priddis and Chris Masten battled hard in the midfield, while Josh Kennedy kicked two goals.

The Eagles have now lost their past five away matches stretching back to last season.

They couldn't capitalise on a promising start. Priddis racked up 12 touches as a slicker looking Eagles side eked out a six-point lead by the first break.

As the heavens opened in the second quarter, the Swans warmed to their task in pouring rain.

Upping the pressure, they dominated for all but a brief period in the third quarter.

The Swans led by nine at half-time, inspired by a spectacular sliding mark from Isaac Heeney and a long goal from full-back Ted Richards, his first major in 71 matches since 2013.

A  Franklin goal early in the third term blew their lead out to 16, but three goals in four minutes wrested the lead back for the Eagles.

That was their last surge and the Swans' relentless pressure forced turnovers, with McVeigh bagging two majors as the home team opened up a 21-point buffer at the last change.

First-year players George Hewett and  Papley goaled early in the final term in which the visitors were outscored 3.4 to 0.1.

MEDICAL ROOM

Swans defender Jeremy Laidler copped a head knock and missed most of the match with concussion so he'll be doubtful next week, while midfielder Harry Cunningham's rolled ankle will be monitored after coming off in the second term, but playing out the second half. 

NEXT UP
Both sides get an eight-day break with the Swans heading north to take on the Brisbane Lions at the Gabba next Sunday, while the Eagles head home to prepare for Collingwood at Domain Stadium.
