Worcester had the much needed bonus point wrapped up in 22 minutes as Sam Betty, Errie Claassens, Lemi and Andy Short all crossed the whitewash before the second half fireworks from Warriors.

Lemi grabbed two more for his treble, Short completed a hat-trick of his own while Matt Kvesic (2), Joe Carlisle (2) and Craig Gillies all crossed for another record win in the Amlin Challenge Cup.

Worcester's win was the club's biggest in European rugby and the 14 tries also surpassed the previous best - both set last Saturday in Spain against Bizkaia Gernika.

Lemi's heroics equaled the club's European record for tries in a game - also held by Rico Gear against GRAN Parma in 2007/08.

Fly half Carlisle contributed 30 points in the game to eclipse the club's previous best of 21 scored by Shane Drahm against Montauban in 2007/08.

Warriors came into the game full of confidence after the bumper win in Spain last weekend and looked to play an expansive style in the opening minutes with Carlisle showing his range of kicks to pin Rovigo back and Gillies disrupting visiting possession.

Lemi and Short combined down the left wing and Ravai Fatiaki smashed into contact before the forwards took the ball hard to the line with James Currie and Semisi Taulava short before flanker Betty bulldozed over for a sixth minute lead.

Short, Schofield, Gillies and Taulava all then brilliantly combined from the restart to keep the ball alive and when the ball was spun wide right at pace by the marauding Kvesic it was the fit-again Claassens who dotted down.

Stefan Basson missed a penalty for hands in the ruck, as Rovigo looked to rally, and then saw a drop goal attempt chip the right hand post as the Italians enjoyed a period of territory.

The relief was short lived though as Warriors again kept the ball alive with neat handling and released Lemi down the wing and he had too much pace as he tore away from the Italian cover defence.

The Rovigo lineout was being repeatedly picked off by Gillies as Worcester looked for the bonus point fourth try with Carlisle cleverly chipping ahead into space but failing to pick up the bouncing ball.

A big driving maul saw Warriors rumble up to the line with Taulava peeling off the back and barreling past bodies. And when the ball was slicked wide Fatiaki took contact and brilliantly flicked out a pass for Short on his shoulder to cruise over for the bonus.

A massive scrum against the head put Rovigo under more intense pressure before a delayed pass from Carlisle sent Lemi away and he pressed the accelerator and tore past tired Italian tacklers for a 31-0 lead inside half an hour.

Basson reduced the lead with a penalty for offside while Warriors missed another certain try as Short stood up strong in the tackle and fed Clarke, but as he drew the final man in his pass just failed to find Claassens on the touchline.

Worcester introduced a new front row for the second half, including Matt Mullan on his 100^th appearance, and Aleki Lutui was soon crashing down the middle to send Italian tacklers flying.

Normal try service was resumed as neat handling down the short-side released Short and he flicked the final pass to send Lemi over for his treble.

Lemi made things happen again as he tore down the left flank, but as Clarke looked to dart away the play was pulled back for crossing. But when the Samoan next touched the ball he again broke into clear air to send Kvesic over.

Hill started to ring the changes as Andy Goode, Blair Cowan and Paul Hodgson all came on while replacement Josh Matavesi had an immediate impact as some audacious skill down the left wing sent Carlisle over to score and bring up the half century.

More incredible handling from Matavesi saw Lemi power down the left wing and score his fourth of the afternoon, before being replaced ahead of the Sale clash on Friday, before Carlisle grabbed his second of the game after more flowing length of the field rugby.

The tries were now flying in as Gillies crashed over after more pack power from the home forwards, Short raced down the left wing to touch down and Kvesic collected a delightful cross field kick from Goode to touch down.

Short grabbed a deserved hat-trick, after Rovigo were caught napping, as Worcester set another European record on a day of big positives for the Warriors.
