Ulster's finest performance of the season earned a stunning victory at Parc y Scarlets on Friday evening.
But how did the individual players fare? Here are our ratings:
Louis Ludik 8: Solid and tidied up well at the back. Took one great high ball in the second half and produced a super try-saving tackle on Evans.
Henry Speight 8: Time with Ulster is nearly up and produced his best performance. Scored a try and was largely great in defence.
Will Addison 9: A horrible start, but his passing and ambition shone through again and his break set Stockdale up. Then came a great try.
Stuart McCloskey 8: Strong as usual. He came so close to scoring in the lead-up to Coetzee’s bonus point try and then won the penalty to seal the victory.
Jacob Stockdale 8: His first chance and what does he do? Scores of course from what seemed an unlikely position. Also helped create Speight’s try.
Billy Burns 8: The first half intercept was scary but he did so much else right. An assist for Speight for that impressive score. He also put in the hits.
John Cooney 7: His first half penalty was rather too ambitious in the conditions. A difficult night for kicking but gave Coetzee an assist.
Eric O'Sullivan 8: Some really good work in the tight and put in an enormous shift defensively to get Ulster this vital result.
Rory Best 9: He worked so hard. His drive off a maul helped in the lead-up to Speight’s score and he was in the thick of the action. Won a crucial penalty too.
Marty Moore 7: One first half scrum showed that Ulster had a clear edge and like his team-mates the defensive work was strong.
Iain Henderson 9: Set tone early with a great turnover and his strength was central to Ulster’s cause. A massive effort in the tackle zone and carried so strongly.
Kieran Treadwell 7: One dummy and break but a knock-on in contact. But the second row also played an important part in this win and in shutting Scarlets down.
Sean Reidy 5: Used as a lineout option at the front, he went in too high and was floored. The result was a penalty against Ulster and the flanker’s early departure.
Jordi Murphy 8: Aggressive defensively, prominent around the fringes but there was one knock-on. When it came to knocking red shirts down, he was immense.
Marcell Coetzee 9: Always visible in the tackle zone, the Springbok won a huge steal on the ground and secured the bonus point try. Stood tall for this one.
Nick Timoney (for Reidy, 24) 8: A great break in the lead-up for Coetzee’s score.
Rob Herring (for Best 69) 7: Helped secure this vital result with his energy.
Tom O’Toole (for Moore 69) 7: Another who gave everything for the five points.
Johnny McPhillips (for Burns 75) 6: Not on long but stood up to what was thrown at him.
