Scarlets back on track, Leinster leapfrogs Ulster
Leinster and Scarlets maintained their impressive Pro14 form, the latter bouncing back from some poor European results.
Scarlets got back to winning ways after its European disappointments with a 30-17 Pro14 victory over Cardiff Blues.
Last year's Pro12 champion has not lost a home league game since the opening weekend of the 2016-2017 season, but was in need of a lift at Parc y Scarlets after beginning the European Champions Cup campaign with successive losses.
After opening up an 18-3 lead at the interval with the aid of tries from Hadleigh Parkes and Ryan Elias, Scarlets saw the lead cut to a solitary point as Willis Halaholo and Lloyd Williams crossed in quick succession for Cardiff.
However, the hosts were soon back in control, Jonathan Evans and namesake Steffan Evans each going over in the final quarter to earn a bonus-point win.
Scarlets sit top of Conference B with six wins from seven, a record matched by Leinster after the latter's 25-10 triumph at Ulster.
Luke McGrath touched down twice as Leinster leapfrogged its opponents on the table.
Cheetahs claimed a dramatic 24-23 victory at Zebre, its first away victory in the Pro14, courtesy of Fred Zeilinga's 80th-minute penalty, while Dougie Fife scored two tries as Edinburgh beat Benetton Treviso 24-13 to avenge a round-three defeat.
