Sam Costelow has taken ownership of the No. 10 jersey in Llanelli on merit as it's revealed he trained with the senior Wales squad ahead of their trip to South Africa this summer.
The diminutive 21-year-old started the United Rugby Championship as the conductor of the Scarlet orchestra as they played out a 23-23 draw with the Ospreys last Saturday evening. Costelow earned himself huge plaudits once again for a high-octane performance, scoring 18 of his side's points.
He was named man of the match after managing to keep the experienced Dan Jones on the bench and Wales international Rhys Patchell, who is said to have responded professionally to the decision, out of the matchday 23 altogether.
