BRUMBIES EDGE WARATAHS IN THRILLING SUPER OPENER

The Brumbies have gatecrashed the NSW Waratahs' homecoming to Allianz Stadium, edging their Super Rugby Pacific rivals in a 31-25 win.

In their first game at the venue in five years, the Waratahs were caught napping at key moments and Stephen Larkham's Brumbies will head back down the highway with a hard-earned victory.

There was some solace for the 25,076 fans present on Friday night, who got to witness the debut of highly-touted teenager Max Jorgensen.

The 18-year-old, who became the youngest Waratahs debutant since Kurtley Beale, grabbed two tries in a promising maiden outing at the top level.

A late penalty from Tane Edmed gave the home side a losing bonus point. 

Crafty Brumbies No.9 Ryan Lonergan was the star of the show for the visitors, grabbing 16 of his side's points - including the opening try - before being subbed off for Nic White in the second half.

Lonergan got his side in the lead when he backed up a pinballing run from Tom Wright, who was all too happy to exploit some sleepy Waratahs defence. 

The Tahs quickly found themselves back level when Jorgensen was able to support a rampaging Angus Bell and shrug off the tackles of Rob Valentini and Alan Alaalatoa to cross in the 15th minute.

Edmed added the conversion, but Bell's night was cruelled not long after due to a foot injury.
