Greater Western Sydney has recorded consecutive wins for the first time in its history, knocking off Carlton by eight points at Spotless Stadium.

It has been slow going for GWS overs its three-year existence, but the fledgling club enjoyed a record score and winning margin over the Brisbane Lions last week before Sunday's first victory over the Blues.

The Giants prevailed 15.10 (100) to 14.8 (92) to improve to 4-9 for the season against a Blues line-up that will now face plenty of question marks in the coming days.

Shane Mumford was immense in the ruck for the Giants, while Dylan Shiel, Adam Treloar, Callan Ward and Stephen Coniglio led a midfield that won the day against its more fancied opponents.

Rhys Palmer kicked three goals and Shiel, Will Hoskin-Elliott and Jonathon Patton added two apiece.

Mitch Robinson (31 possessions, 10 clearances) had a day out for the visitors, who lost Marc Murphy (hamstring tightness) before the opening bounce.

Bryce Gibbs, Chris Judd and Andrew Walker also contributed to the cause and Troy Menzel kicked three goals.

But they couldn’t prevent a fourth straight Carlton loss, leaving it also 4-9 for the year and out of finals contention on a tough day for veteran coach Mick Malthouse.

It was a free-flowing contest from the opening bounce, with the two teams kicking 5.1 apiece in an entertaining first quarter.

Two great goals on the run from Shiel and Devon Smith helped GWS to an early 19-point lead, but Carlton responded, kicking three late goals to leave the match all tied up after one quarter.

A neat effort from Gibbs gave the Blues an early second-quarter lead, but from that point on it was all GWS, slamming through four straight goals as the Giants took a deserved 22-point lead into the main break.

The Giants' 10.2 to half-time represented their biggest ever first-half score, surpassing the 9.5 they kicked against Geelong last season.

The scoring dried up in the third term, with the teams trading goals until back-to-back majors from the Blues made it an eight-point game deep into the quarter.

A late Rhys Palmer goal then restored a 14-point buffer for the Giants and they looked likely winners.

So it proved, with the team withstanding a late Carlton fightback for another significant day in the young club's history.
