Pierre Castillon

Born on 20 September 2003, Pierre Castillon is a French flanker who has come through the system at Aviron Bayonnais. A back-row forward defined by his work rate, Castillon is an industrious presence at the breakdown and a reliable defender who covers plenty of ground across the 80 minutes. His game blends honest ball-carrying with a willingness to compete for turnovers and chase kicks, the kind of unglamorous contributions that underpin a forward pack. As a young player developing within a Top 14 squad, he continues to add physicality and decision-making to his repertoire. Castillon offers Bayonne energy and dependability in the loose forwards, and is part of the club's crop of homegrown talent pushing for greater involvement at senior level.
