A second-half yellow card to Scotland fly-half Finn Russell proved decisive as the home side edged a tight encounter to ensure they bounced back from their defeat to Ireland in the opening round of fixtures.
Darcy Graham’s first-half try for Scotland was cancelled out by Welsh prop Tomas Francis as the sides entered the break level at 14-14 with the rest of the points coming from the boot of Russell and Wales captain Dan Biggar.
Russell and Biggar traded penalties in the second-half but it was Biggar who made the difference with the winning drop goal seven minutes from time while Scotland were down to 14 men after Russell was sin-binned for a deliberate knock-on.
