Glasgow were knocked off the top of the RaboDirect Pro12 table after going down to the Scarlets, who climbed back into the play-off places with a comfortable win at Parc y Scarlets.
The Scarlets were indebted to tries from hooker Ken Owens and Liam Williams as well as 19 points from the boot of outside-half Owen Williams.
Ulster replaced Glasgow atop the standings after they won 31-5 at home to Newport Gwent Dragons, while the Scarlets’ presence in the top four could be short-lived if the Ospreys beat Treviso at the Liberty Stadium tonight.
Ireland winger Tommy Bowe marked his return to the starting line-up after being out with injury with the opening try and Ulster then added to that with scores from the impressive Stuart Olding, Darren Cave and Paul Marshall while Ruan Pienaar – who started at out half – kicked all the conversions and added a penalty for an unblemished night from the tee.
Elsewhere in tomorrow’s card, Cardiff Blues host Zebre and Leinster travel to Munster.
