Ospreys saw off a second-half comeback from Newport Gwent Dragons to clinch a hard-fought 12-7 Guinness PRO12 win and make it two Welsh derby victories out of two in the space of six days.
Bath fly-half Rhys Priestland will be available for Wales after all this season having performed a U-turn on his decision to take a sabbatical from international rugby.
The Ospreys claimed their 12th win in 15 games over the Scarlets, winning an entertaining Guinness PRO12 derby 27-26 in Llanelli – re-vitalising their play-off hopes.
