Discipline was also the key factor in Scarlets missing out on a significant result in Glasgow, according to captain Josh MacLeod.
But unlike Cardiff, Scarlets let slip a 15-7 lead in the narrow loss at Glasgow Warriors to end their three-game winning run.
“I couldn’t have asked for more from the players but there’s only so much defending you can do,” said MacLeod, who weighed in with a match-leading 26 tackles.
“It felt like we spent three-quarters of the first half defending on our try line and, in the end, that takes it out of your legs.”
Scarlets still had a chance to win it late on as Ioan Lloyd missed a penalty and saw a last-gasp drop goal charged down.
But the decision to turn down an earlier – and easier – penalty kick at goal was met with a shake of the head from head coach Dwayne Peel.
He said afterwards: “It was a decision by the boys. They had momentum but we will review it. But that’s not why we lost, we weren’t clinical enough.”
