SCARLETS European hopes were dashed after Ulster claimed an upset victory at Parc Y Scarlets yesterday, Friday (Dec 7).
The win boosts the Irish sides chances of qualifying from Pool 4 and securing a quarter-final spot.
Rhys Patchell kicked an early penalty to get the home side on the board but that was cancelled out by John Cooney.
The first try came from Jacob Stockdale following excellent work in midfield by centre Will Addison. Cooney was wide with the conversion.
Scarlets responded well with Steff Evans going over to give his side the lead, Patchell adding the conversion.
A poor clearance kick by Patchell resulted in an strong attack from Ulster, who were awarded when wing Henry Speight scored in the corner.
A huge gaping whole in the Welsh sides defence allowed Man of the Match Addison to run in under the posts. Cooney slotted the extra points.
A slick offload from Johnny McNicholl sent Evans over for his second try of the evening but that was cancelled out when number eight Marcell Coetzee replied shortly after with his sides forth try.
With the home crowd getting behind their team, substitute Dan Davis darted over in the corner to give the Scarlets hope. Dan Evans took the conversion quickly with seconds to go and managed to squeeze through the posts.
Despite a late attempt to gain victory, a turnover at a ruck resulted in Ulster holding on to win.
Final score: Scarlets 24 – 25 Ulster
Man of the Match: Will Addison
The Scarlets will now travel to the Kingspan Stadium in Belfast to once again face Ulster next Friday (Dec 14).
