Greater Western Sydney has stormed into the top eight for the first time in almost two months after edging Hawthorn by 11 points at Spotless Stadium.

Key forward Jonathon Patton largely struggled on Saturday night, copping a painful blow to the knee during a ruck contest, registering three behinds and putting another set shot out on the full.

But the former No.1 draft pick stood up when it counted most, booting the sealer from a tough spot after he was awarded a free kick with a tick under four minutes remaining.

Hawthorn ball magnet Tom Mitchell had a game-high 50 disposals, while GWS co-captains Callan Ward and Phil Davis starred to help their side prevail 13.17 (95) to 13.6 (84).

The result rocketed the Giants, who slipped out of the top eight in early May during a four-match losing streak, to sixth on the ladder.

They have won four on the trot and next tackle West Coast, Richmond and Port Adelaide in a challenging stretch that has the potential to make or break their campaign.

GWS won clearances 51-28 and had 53 more contested possessions than Hawthorn but couldn't put the Hawks away until late in the final quarter.

The Giants snatched a 24-point lead after their most productive first quarter of the year, overwhelming the Hawks with frenetic pressure and frantic ball movement while kicking five goals – three off the boot of Rory Lobb.

Hawthorn reduced the margin to a single point during the third term, but GWS rallied with three quick goals before three-quarter time.

Ben McEvoy, Luke Breust and Paul Puopolo trimmed the Giants' buffer to five points early in the final term but Lachie Whitfield and Patton responded with clutch goals when the game was on the line.

Patton loomed as the man most likely to fill the immense void left by fellow foundation Giant Jeremy Cameron, who sat out the first of five games he'll miss through suspension.

Instead, it was Lobb who caused the visiting defenders plenty of early headaches, although he faded after his incredible start.

Lobb, who left the ground in an ambulance just three weeks ago, looked set for a big night in his return from a fracture in his thoracic spine.

But he was one of many forwards responsible for the home side's inaccurate haul of 1.8 in the second term, with the sole goal coming courtesy of a contentious free kick to Harry Himmelberg.

"That's almost a Rancey (Alex Rance) dive," Hawks defender Ben Stratton fumed to the umpire.

Hawthorn's Jack Gunston was a late scratching because of a corked calf and Will Langford suffered a finger injury.
