Finals-bound Perth Glory enhanced their reputation as the A-League’s best travellers with a 3-0 away triumph against Adelaide United on Sunday.

The Glory, through goals to Shane Smeltz, Steven McGarry and Liam Miller, rose to fourth on the ladder as second-last Adelaide sank further into the mire.

Perth stretched their unbeaten streak to seven games – remarkably including five away fixtures.

Smeltz and McGarry scored in a six-minute, opening-half burst which came after Adelaide striker Bruce Djite butchered three golden chances at Hindmarsh Stadium.

Djite inexplicably hit a side post from five metres out in the seventh minute with Glory goalkeeper Danny Vukovic well beaten.

Five minutes later, the Reds striker missed another sitter when a close-range attempt sailed over the crossbar from prime scoring position.

And within a minute, Djite was exasperated again – having turned his defender, he launched a right footer which drifted across the goal face.

Perth then made Djite and Adelaide pay the ultimate price, with Smeltz poaching his third goal in two matches in the 14th minute.

The Glory frontman pounced when Adelaide defender Nigel Boogard blundered and failed to control a regulation throw-in.

Smeltz seized on the mistake, stealing possession before turning past Boogard and finding the net with a classy right-footer.

Adelaide’s shock at Smeltz’s against-the-flow goal turned to utter dismay in the 20th minute when McGarry scored.

The Scot midfielder, on the goal line, found himself in the path of a deflected Todd Howarth shot.

McGarry instinctively swung his leg waist-high and all but kicked the ball from the hands of Adelaide ‘keeper Eugene Galekovic and into the net.

After protecting their 2-0 nil for much of the second half, Perth’s Miller put an 82nd-minute exclamation mark on the result with a clever goal.

Miller sliced through lax Adelaide defence, neared the penalty spot and coolly slotted low past the despairing dive of Reds skipper Galekovic.
