The Scarlets banished the memories of several unlucky results in Europe's biggest competition with a stunning win over Munster in their Heineken Cup quarter-final clash at Stradey Park.

The defending champions - many of whom were coming off the back of Triple Crown glory in the Six Nations - were on the back foot from the kick-off, and looked out of it at 17-0 down at halftime. They came back with a try to winger Ian Dowling and plenty of pressure, but the Scarlets scored through full-back Barry Davies and held on for a famous victory.

The Scarlets claimed first blood after some excellent work from their pack. Scrum-half Dwayne Peel chipped ahead, and winger Dafydd James extended his Cup try-scoring record by powering over the top of three defenders for his 28th score.

Munster general Ronan O'Gara kept the Scarlets on the back foot with some clever touch-finders, but the Irish lineout - missing Paul O'Connell - couldn't take advantage.

With the lineout struggling, and Ireland's Test tighthead prop John Hayes being found out by the Scarlets' front-row, Munster's grasp on the Heineken Cup was beginning to slip.

O'Gara's kicking out of hand was impeccable, but two missed shots at goal proved costly. The Scarlets' super-boot Davies slotted a long-range goal on to and over the cross-bar and a try to flanker Gavin Thomas - with a hint of a double movement - in the final move of the half gave the home side a daunting 17-0 lead at the break.

Scarlets winger Mark Jones opened the second half by skinning opposite number John Kelly to score what looked like the match-clinching try, only to be called back for a forward pass. Referee White further endeared himself to the crowd in the next phase of play by over-ruling his touch judge's opinion and not giving the Scarlets a penalty when the same player looked to have been taken out without the ball.

O'Gara started showing the strain and had to be cautioned by White for swearing, but he made sure the Irish province troubled the scorers with a penalty goal from point-blank range on the hour mark.

Things looked grimmer for home fans when replacement lock Inoke Afeaki was yellow-carded two minutes after coming on to the field, and it was game-on when Dowling scored in the corner, courtesy of a forward pass from All Black legend Christian Cullen.

The score - unconverted by O'Gara - made it a nine-point ball-game with as many minutes left on the clock, but a superbly executed try finished off by Davies settled the match. Scarlets and Wales backrower Alix Popham produced a bone-shattering tackle on Munster flanker
David Wallace, and some classy work from Stephen Jones, Peel and centre Regan King gave Davies a score that brought the biggest cheer of the night.

A consolation try to Munster replacement Donnacha Ryan was barely noticed as west Wales celebrated.
