Edinburgh battled past a spirited Scarlets side to secure a crucial bonus-point win in their bid to reach the United Rugby Championship play-offs.
Joe Roberts and Sam Lousi crossed to give Scarlets an early 14-point lead, with Ben Vellacott halving the deficit with a try before half-time.
A try from Magnus Bradbury and another from Vellacott swung the momentum in Edinburgh’s favour after the break and, although Roberts’ second try drew Scarlets level, Harry Paterson’s try for the hosts proved decisive.
Sitting 13th and 15th respectively in the table coming into the match, both sides knew the importance of a win if they are to mount a realistic bid to reach the top eight.
The visitors started the brighter and camped themselves in the Edinburgh half for the opening quarter without finding a way through.
That was until Roberts sold a dummy and ghosted through all too easily to run it in from halfway.
Things got better for the Welsh side when Lousi burrowed over in the corner to round off a period of pressure and establish a 14-point lead.
Edinburgh needed a response and they got it when Wes Goosen jinked his way through the Scarlets defence and put Vellacott away to score.
Trailing by seven at the break, Edinburgh came out firing early in the second half and struck with two quick tries.
Paterson launched a counter-attack from deep and a succession of offloads and carries took Edinburgh into the red zone. The ball was spun wide to Bradbury and the big number eight did well to collect the pass and power his way through to the line.
Ross Thompson converted to level things up and Edinburgh were soon in the lead for the first time.
Goosen did brilliantly to ride a couple of tackles and link up with Lang, who sent Vellacott scampering away for his second try of the evening.
Edinburgh were on top, but their momentum was checked when Paterson was sent to the sin-bin for a deliberate knock-on.
Scarlets wasted little time in making their numerical advantage count, slinging the ball wide for Roberts to force himself over for his second try to level things up again at 19-19.
Paterson had barely returned to the action when he came up with Edinburgh’s fourth try.
The full-back launched a bomb downfield, Leggatt-Jones made a mess of his return kick to allow Paterson to charge down, gather and go over for the try that sealed the win for Edinburgh.
The bonus-point victory moves Edinburgh up to 11th in the URC table before Saturday’s matches, with Scarlets remaining in 15th.
