Scarlets have cracked the Guinness PRO12 top four for only the second time since the play-offs were introduced and their three British & Irish Lions will hope the journey does not end there.
They head to Leinster for the semi-final clash with Jonathan Davies and Liam Williams both named in the starting XV.

It could be the last game in Scarlets colours for Williams who lines up on the wing, while Davies – who will be heading on his second Lions Tour this summer – is at outside centre.
LIAM TO LEAVE ON A HIGH
Liam Williams will join up with his new club Saracens after the Lions Tour to New Zealand is over.
But before that he will be desperate to send off the Scarlets in fine style and get them to a first ever Guinness PRO12 Grand Final.
Equally comfortable at full back or wing, Williams has been a stalwart for his home region ever since breaking onto the scene back into 2011.

Now the 26-year-old is a mainstay of the Wales international side, heading on his first Lions Tour this summer and has opted to try out pastures new from next season.
But not before he and Scarlets have given Leinster a run for their money at the RDS Arena.
DAVIES IS A DIAMOND
One of the break-out players of the last Lions Tour that saw him start all three Tests against the Wallabies, Davies will be in the famous red jersey again this summer.
And after a spell in France with Clermont, the centre is back at his home region the Scarlets and aiming for a Guinness PRO12 final.
The No 13 started all three summer Tests against New Zealand last year for Wales and all five games of this year’s RBS 6 Nations.
And the 29-year-old appears to be rounding into his best form at just the right time with knockout club rugby followed by a Lions Tour to the home of the world champion All Blacks.
