Edinburgh fans were thrilled to witness something they will not want to see repeated in Paris on Sunday - an Argentinian scoring a great try.

Prop Augusto Allori powered in for their only score against the Ospreys at Murrayfield, but it was not enough to pave the way for success in Andy Robinson's first Magners League match in charge of the capital brigade.

Both sides looked jittery during the opening sparring session, with Shaun Connor and Phil Godman trading penalties in quick succession.

Gunners began to seize the initiative and, after a series of well-controlled phases, Allori bulldozed his way over for the crucial touchdown.

Godman followed up with the conversion to give his side a useful seven-point cushion after 25 minutes of frantic action.

And the stand-off provided a further boost on the stroke of the interval when he banged over another confidently-struck penalty from 25 metres.

Edinburgh ruled the roost in the initial stages of the second half, but the Ospreys defence was impressive as they staved off a string of raids.

Having weathered the storm, the Welshmen came into the picture, with Gavin Henson testing the home markers on several occasions.

And their endeavours were rewarded as Andrew Bishop slotted an awkwardly-angled penalty to set up a tense finale.

At the other end, Godman watched in frustration when his next effort slipped wide of the target.

The excitement level soared as Jonny Vaughton darted in for a superb opportunist try in the corner. Owen's kick from the touchline was spot-on.

Ospreys stepped up the pace in their quest for a clincher - but Edinburgh held firm for share of the spoils thanks to a missed penalty by Owen in the dying seconds.
