The Scarlets failed to celebrate Robin McBryde's testimonial match with a win as English Premiership side Worcester spoiled the Stradey Park party. Worcester finally turned their pressure into points when Ben Hishelwood and Thomas Lombard scored after the break.
The home side rallied in the final 10 minutes and tries from Reagan King and Dafydd James gave the scoreline an air of respectability.
But Worcester were by far the better side and held on with ease at the end.
