Cathal McCarthy, born on 31 August 2006 (age 20), is a Republic of Ireland central defender whose senior career is already centred firmly on Kilmarnock.
Wearing the number 4 shirt, McCarthy has made 10 league appearances for Killie in the 2026-27 season, scoring once. He has also played once in the League Cup, taking him to 11 appearances and one goal across all competitions for the club.
That Kilmarnock spell is the substance of his career to this point: a young defender building his first proper body of senior football, with one productive league season already behind the basic outline.
