The hosts came into the game on the back of a run of seven wins in eight games and looked confident from opening kick-off.

The hosts forwards led the way with a stream of turnovers and penalties to lay the platform, but the Scarlets were also happy to spread the ball wide to create opportunities.

Blindside wing Steff Evans and full-back Johnny McNicholl created the space on the left for wing Ryan Conbeer, who still had a fair bit to do to muscle his way over the line for the try.

There were no such problems for the second try as flanker Vaea Fifita earned himself a clear 60-yard run to the line after picking off a bobbled pass inside his half.

The centre atoned with the break which led to a short-range try for prop Murray McCallum, but it was the home side who finished the half the stronger with lock Sam Lousi offloading for wing Evans to score.

The wing turned provider early in the second half, bumping off the tacklers to send the ball wide for Conbeer to add his second try.

The Scarlets were boosted by a strong opening half and grabbed another with McNicholl deciding to run from deep, with a chip and chase seeing him past the first defenders, a pass putting Fifita in for a run to the line, before he passed to scrum-half Gareth Davies once over the try line.

Edinburgh did have a spell of pressure which resulted in a try for prop Boan Venter, a predictably short-range effort after number eight Viliame Mata had lured in the defence.

The Scarlets had the last word as they ran through their party pieces in the closing minutes, replacement Eddie James making his debut and scoring a try under the posts.
