SOUTH African Eduan Swart was the unlikely hero with a 84th-minute try to give the Scarlets a much-needed victory.
The replacement hooker just managed to get the ball down before going into touch as he rounded off a lineout maul drive which featured most of the backs.
It’s just the Scarlets’ third win from 16 matches in all competitions this season and coach...
