Nic Naitanui has kicked a last-second goal to enhance West Coast’s top-four AFL prospects and dent those of GWS, with the Eagles grabbing a last-gasp one-point away win over the Giants.

The Eagles moved level on points with the Giants as they ground out a thrilling 14.13 (97) to 14.12 (96) victory on Saturday at Spotless Stadium.

GWS held a 24-point lead in the second quarter and were up by 23 at the last change.

However, the Eagles kicked six goals to two in the final quarter, with Naitanui snapping truly just before the fulltime siren.

It was the Eagles’ first away win over a top-eight opponent this season and just the Giants’ second home loss.

Coleman Medal leader Josh Kennedy kicked 3.3 for the Eagles, who had the best player on the ground in midfielder Luke Shuey, who bagged 38 touches.

Giants’ back-up ruckman Rory Lobb, who has reportedly expressed an interest in returning to his home state of WA, kicked four goals, including what looked to be the match winner with just over a minute to go.

Midfielder Dylan Shiel logged 30 touches for the Giants.

GWS led for most of the game, but West Coast hit the front briefly in the third term before the Giants kicked the last five goals of that quarter.

Giants defender Adam Kennedy was taken off the ground in the final quarter after his head hit the ground following a sling tackle from Simon Tunbridge.
