Edinburgh slumped to an embarrassing defeat, hopeless against the Ospreys, with feeble tackling and masses of mistakes leading to this humbling experience at the Liberty Stadium.

The rampant Ospreys ran in nine tries - in the end it was almost like an unopposed training session for the home side as they maintained their unbeaten start to the season.

For Edinburgh, their opening win in Munster two weeks ago already seems an eternity away and there must be some serious rethinking at BT Murrayfield to avoid a repeat of this showing. The nine tries conceded was a record in the PRO12; it was also their biggest defeat in the league.

Coach Alan Solomons did not pull his punches. "All of us feel terrible about it, it was a poor performance," he admitted. "We have got to properly analyse what happened, we cannot just look at he scoreline blindly. We need to go away and take the lessons and keep our composure. We have to put this behind us, I have no doubt we can and will do that."

Edinburgh could hardly have got off to a more disappointing start. First there was an aimless kicking battle between the two teams, then Ospreys full-back Dan Evans made a half break when he decided to keep the ball in hand. Worse was to come as scrum half Rhys Webb darted from the base of the ruck, got clear of the forwards and was able to round full-back Jack Cuthbert with ease and then straighten up to score under the posts. If defenders had tried to tackle instead of ankle tap Webb, they should have stopped him.

If that had been a superb run from just inside the Edinburgh half, he scored his second try from just outside the Edinburgh try line - diving over from a ruck after the Ospreys had laid siege to the line.

With Dan Biggar converting both, the Ospreys took a commanding lead despite the one Edinburgh penalty slotted from in front of the posts by Tom Heathcote.

However Edinburgh were struggling to get a foothold, not least because the lineout was going badly wrong with James Hiltebrand regularly watching his throw sail over the jumper. That resulted either in lost or bad possession for the visitors.

The Ospreys were bound to capitalise. A scrum penalty given against Edinburgh tighthead Willem Nel for boring in allowed the Ospreys a lineout 20 yards out from the line. They took the catch and practically ran the rolling maul to the line, Alun Wyn Jones in the vanguard as No.8 Dan Baker was able to touch down.

Edinburgh finally got a try of their own, though it did come after a bit of good fortune. Left wing Tim Visser was able to fly hack a loose kick ahead into space and though he was caught after regathering possession he gave a clever floated pass to supporting flanker Hamish Watson to score in the corner. Heathcote converted from wide out.

Biggar landed a penalty on the stroke of half-time to give the home side a 24-10 lead at the break.

Heathcote narrowed that gap with a penalty in off the post just after half-time, but the Ospreys got their bonus point try shortly afterwards and again it was far too easy.

Right wing Jeff Hassler burst into the line on the left and was able to cut straight through towards the posts. He was hauled down just short, but the ball went wide for Biggar to get the easy score against the stretched defence. He also converted.

Hassler then picked up the ball from a loose Edinburgh pass when attacking the Ospreys line. Edinburgh's players were lined up in attack and could not catch the wing as he raced the length for his side's fifth try. Even when the Ospreys flanker Justin Tipuric was sin-binned normal service carried on.

Centre Jonathan Spratt went over in the corner, then left wing Hanno Dirksen went through the defence to rub salt in the wounds, with Tom Grabham sprinting over from an interception, before Tyler Ardron skipped over for the final try.
