Lewis Mayo, born on 19 March 2000 (age 26), is a Scottish central defender now with Aberdeen, where he wears squad number 23.
His early senior career was shaped by loan football, giving him the sort of first-team grounding young centre-halves tend to need before anyone takes them too seriously. The spell that came to matter, though, was Kilmarnock.
Kilmarnock has defined Mayo’s career to this point. Across four seasons there, he made 131 league appearances and scored once, becoming a regular presence rather than a passing squad option. His busiest league campaign came in 2023–24, when he played 36 times and got his league goal.
He is now at Aberdeen. In 2026–27, he has made seven league appearances and scored once, along with six League Cup appearances and one in the Scottish Cup, giving him 14 appearances and one goal in all competitions for the club.
Mayo’s career has moved from early development loans into a substantial Kilmarnock spell, and now on to Aberdeen, where he is continuing as a first-team defender.
