Scarlets boosted their European Champions Cup qualification ambitions by seeing at Parc y Scarlets . The home side remain outside of the top six , but are now just three points behind Connacht in the battle to book a place among Europe 's elite . It was a deserved win for the Llanelli-based region , who put a big dent in Leinster 's play-off hopes with just five rounds of action remaining . Both sides welcomed back Six Nations squad members with British and Irish Lions prop Cian Healy making his first Leinster start since September , while Wales centre Scott Williams had not pulled on a Scarlets jersey for six weeks . And the Scarlets ' vice-captain came to the fore in a bright start from the home side , which was rewarded with a penalty from fly-half Steve Shingler after 10 minutes . However , Leinster began to grow into the game as the half wore on and on 18 minutes they showed the clinical edge of champions to claim the game 's opening try . After Leinster had set up an attack in the home 22 , former NRL star Ben Te ' o cut an exquisite angle through the Scarlets midfield before stepping his way to score at the posts . Fly-half Jimmy Gopperth landed the simple conversion . The Wasps-bound number 10 added another three points following more pressure from the visitors , but Scarlets responded strongly and crossed for their first try just before the half-hour mark . Some slick handling by the home backs had Leinster on the back foot and Scotland back-rower John Barclay did well to squeeze in at the corner - although it needed the television match official to confirm the number eight had avoided touch in the process of touching down . Shingler was short with the conversion and it meant Leinster held a slender 10-8 advantage at the interval . However , a well-worked team try from the Scarlets wiped out that advantage 11 minutes after the restart . After strong work from the forwards which took play to the Leinster line , the home side appeared to have butchered an overlap . However , they regrouped well and silky hands from Kiwi centre Regan King put full-back Jordan Williams over . A long-range Gopperth penalty reduced the arrears to two points , then it needed a try-saving tackle from Barclay to deny opposite number Jack Conan , with James Davies claiming a crucial turnover . The outstanding Barclay was then involved at the opposite end of the field , bursting through to set up the Scarlets third try , finished off with an outstretched hand by replacement Rory Pitman . Shingler could n't land the conversion and seven points separated the sides going into the final 13 minutes . Replacement Rhys Priestland landed a penalty to put more distance between the sides and Leinster left empty handed after a score by full-back Zane Kirchner was ruled out by the TMO in the final minutes .
