KIEREN Jack and Jarrad McVeigh have turned on sizzling performances in the Sydney Swans' demolition of cross-town rival Greater Western Sydney on Saturday night.

After some early resistance from the Giants, the Swans powered away to a 94-point win, 19.18 (132) to 5.8 (38).

The Giants' night was further soured by a serious injury to Luke Power, who copped a knee to the head and chest and was taken from the field in a stretcher in the final term.

This season the Swans have been boosted into the top four on the back of some flying starts, but in this derby it was a ruthless second half that underlined their victory.

The Giants did something Geelong couldn't manage last week - reining in the Swans' early momentum to trail by only 14 points at quarter time.

The Swans opened the second quarter in fine fashion when Josh Kennedy sharked a Mike Pyke tap and kicked a goal out of the air.

They booted five for the term and kept the Giants to just one goal to take a 37-point lead into the main break - but GWS still managed to curtail the Swans' momentum for large sections of the quarter.

However, any lingering thoughts of an upset were swiftly removed by the Swans when Brett Kirk medallist Jack seized control of the game.

Jack finished with 33 disposals and six tackles to be named best on ground, while McVeigh had a game-high 37 touches.

GWS coach Kevin Sheedy suggested pre-match the fixture would be a yardstick for how much his side had developed since a 63-point loss to the Swans in round one.

Instead it showcased the Swans' progress - they were a far more ruthless team compared to the one that managed 14.16 against a more inexperienced GWS outfit in the season opener.

A crowd of just 22,565 - well down on the tally of 38,203 that witnessed the Giants' maiden AFL match - were treated to a unique match.

Pressure from both sides ensured plenty of stoppages and a largely scrappy contest, but a series of spectacular solo efforts provided plenty of fodder for both clubs' highlight reels.

Jetta, who took his season tally to 31 goals with three majors, started the show in the first quarter by calmly slotting his set shot after marking the ball close to where the 50m arc meets the boundary line.

However the Giants cut down the Swans' free space - best underlined by a 24-9 tackle count at quarter time - and Jeremy Cameron reduced their buffer to 14 points at the first break with a deft banana kick.

GWS midfielder Rhys Palmer kept his side in the contest in the second term by climbing over a pack and kicking truly, but Cameron, Jonathan Giles and Jonathon Patton all missed easy goals that would have trimmed the deficit.

Jack continued to shine in the third, kicking two cracking goals - one of them a remarkable kick from the boundary line - as the Swans powered away to a 10-goal lead at the final change.

Chad Cornes was brave for GWS and Toby Greene was prolific with 31 touches, but there was little they could do to stop the Swans' march to the finish line .... and September.
