That third minute try was followed by scores from Nikki Walker, Shane Williams (2), Sonny Parker and Mike Phillips and a second for Byrne.
Worcester did manage a consolation through Craig Gillies but Mike Ruddock’s side looked outclassed against the Magners League champions and on current form they will struggle to get past the group stage of this competition.
The Ospreys, however, will have entirely different expectations. Last year’s beaten finalists have their World Cup contingent back in the fold and will be looking to go one better than last year when they were narrowly defeated by Leicester Tigers in the final.
Ospreys Coach Jones said, “As the game went on we grew with confidence and it was nice to see the boys gel together. We looked very confident out there and it is great when we play with no fear.”
And in the wake of Cardiff’s impressive victory over Sale last night Jones said, “You have to say that all the Welsh sides are looking strong.”
