Scarlets star Williams to sign off in style
Eliminated Ulster still ready to dig deep
Scarlets v Ospreys
Sky Sports 2 & BBC Wales, 5.15pm Saturday
There's little up for grabs in the final round of Pro12 action with Leinster and Munster already guaranteed home semi-finals, and barring a freak result for Ulster their opponents will be Scarlets and Ospreys, who do battle at Parc y Scarlets.
If the Ulstermen should somehow manage a landslide victory over Leinster, Ospreys would be the side to miss out. But that scenario is unlikely to weigh heavily on the players' minds.
So there may be a lack of intensity but it's still a derby encounter with pride at stake and the final day can often produce entertaining, high-scoring showdowns.
Wales and now Lions winger Liam Williams is leaving the Scarlets for Saracens at the end of the season, and if this should turn into an open contest he looks value at 15-8 to mark his farewell with a try.
There will also be some goodbyes at the Kingspan Stadium as Ulster face Leinster. Ruan Piennaar, whose scrum-half play has been the side's heartbeat since he arrived in 2010, and number eight Roger Wilson, the province's most capped player making his 221st appearance, are playing their last games.
Ulster's only league defeat at their Belfast base this season was by a single point to Munster and they should be fired-up against a Leinster outfit with little to play for.
