Ospreys winger Tommy Bowe ran in four of his team's ten tries against Treviso to set up a 68-8 Heineken Cup win at the Liberty Stadium on Saturday.
Bowe set the tone by scoring three of his four tries in 23 minutes as Ospreys eased past their previous best Heineken Cup victory of 48-17 against Ulster last season.
Scotland international Nikki Walker added a try double, and with flanker Jonathan Thomas also touching down before the break, Pool Three whipping boys Treviso trailed 40-8 at half-time.
The second period proved more of a contest as Treviso restricted Ospreys to a Lee Byrne try during the third quarter, but substitute Shane Williams then pounced to give his team an inevitable half-century of points.
Replacement hooker Ed Shirvington and Bowe completed the rout with touchdowns nine and 10 - fly-half James Hook booted nine conversions - while Treviso had to content themselves with an early Marius Goosen try and Andrea Marcato's 39th-minute penalty.
The Italians, despite recording a solitary victory from their last 21 Heineken games, took a sixth-minute lead when wing Goosen rounded off an impressive attack by crossing in the corner.
The Ospreys quickly re-focused and drew level after Bowe gathered Hook's kick to touch down.
And Treviso were then blown away by three further Ospreys tries during a devastating seven-minute spell that underlined the gulf in class.
Jonathan Thomas sparked the points burst, then Treviso had no answer to number eight Filo Tiatia's surging midfield run that ended with Byrne handing Walker a scoring pass.
The bonus point try - scored by Bowe - arrived after 26 minutes, but Ospreys were in no mood to spare Treviso further misery.
Bowe completed his hat-trick eight minutes before the interval, which made him the first Ospreys player to score three tries in a Heineken Cup game, then Walker pounced following more optional Treviso defending.
With Hook converting five of Ospreys' first six tries, the Welsh side hit 40 points at comfortably more than a point a minute, leaving Treviso in disarray.
Marcato kicked a penalty for the visitors during first-half injury time, while Walker limped off to be replaced by the last player Treviso wanted to see - Wales wing wizard Williams.
The Ospreys were back in try-scoring mood within two minutes of the restart, where Hook weaved through a gap and Tiatia sent Byrne over.
Treviso coach Franco Smith made a raft of substitutions in an attempt to stem the tide, but replacement hooker Andrea Ceccato only lasted eight minutes before receiving a yellow card.
The game inevitably drifted through a quiet phase, especially with Ospreys losing skipper Paul James to the sin-bin, and it was simply a question of how many more tries Ospreys would score.
Waters should have scored for the visitors, but he was brilliantly held up by Williams, who then added an eighth try following superb approach work by centre Andrew Bishop.
Two more scores followed, giving Ospreys a winning margin of 60 points and leaving Treviso once again reduced to Heineken Cup also-rans.
