Scarlets took a giant leap towards the European Rugby Champions Cup quarter-finals by dismantling Bath at the Rec with a scintillating display of attacking rugby.
Bath, though, are facing being frozen out of the last-eight picture after their red-hot opponents ran in tries by lock Tadhg Beirne, wing Paul Asquith and Wales global centres Scott Williams and Hadleigh Parkes. The Scarlets, meanwhile, will battle it out with Toulon in what is sure to be a fascinating climax to the group stage. Kick-off is just over 50 minutes away at 7.45pm.
The Pro14 side, without the suspended Steff Evans and injured Leigh Halfpenny, produced some scintillating attacking rugby to dismantle Todd Blackadder's team and move four points clear of them and Toulon, who take on Benetton Treviso on Sunday. It is all there for Ken Owens side and their magnificent fans will have a huge role to play.
Scarlets number eight John Barclay's penalty indiscretion - he roamed offside to halt Bath scrum-half Chris Cook just two metres from his own line - gave referee Jerome Garces little option but to sin-bin him.

But the Scarlets were untroubled by his departure, rocking Bath on their heels again as they claimed a second try when Patchell moved possession wide, Parkes acted as the link and Asquith crossed unopposed in the corner.
Dan Jones converted off the touchline to add to his two conversions and penalty in the first-half.
The first score in the second half was going to be vital and there was no let-up from the Scarlets.
