#3. Ioan Nicholas & Nigel Owens
The cousin of legendary referee Nigel Owens became the youngest player to represent the Scarlets (17 years and 134 days) when he appeared in a pre-season friendly against Jersey in August 2015, making his Guinness Pro12 debut against Ulster the following month. A Wales U20s international at centre, Ioan has played most of his senior rugby for the Scarlets on the wing.
