Ospreys made an impressive start to the new RaboDirect Pro12 campaign with a 27-3 victory over European champions Leinster.
Scrum-half Rhys Webb made one try and scored another as the Ospreys produced a stunning first-half display on their way to a fine win.
Webb started and finished a fine move inside the Ospreys' own half after just two minutes and Dan Biggar successfully converted to get the Welsh region off to a flying start.
Biggar successfully landed a penalty and a drop goal in the first half and also converted two further first half tries against the European champions.
Left wing Hanno Dirksen slid over in the left corner at the end of the first quarter for the second try before flanker Justin Tipuric put the seal on an impressive first half effort when he pounced on a kick ahead from the influential Webb to ease Ospreys into a 27-3 interval lead.
Below-par Leinster, missing 13 internationals on World Cup duty, improved after the break but they were unable to build on Mat Berquist's solitary penalty goal despite Tipuric finding himself in the sin-bin.
Centre Ashley Beck, another to impress on the night, held up Kevin McLaughlin ten minutes into the second half to keep the Welsh region's try-line intact.
A flurry of substitutions took any momentum out of the game and neither side were able to make any impression on the scoreboard for the remainder of the game as the second half ended pointless, much to the frustration to the disappointing crowd of 5,424.
