A former Ross County youth, Danny made his senior debut with Wick Academy in the Highland League after leaving Victoria Park aged 17. Mostly appearing as understudy to his brother Sean, he left the Caithness club at the end of the 2017-18 season.
As the son of long time Tain St Duthus goalkeeper DJ McCarthy, Danny has Saints in his blood and did not hesitate when offered the chance to join the club. After just two games at the start of the 2018-19 season though, Danny was tempted away to Brora Rangers.
He returned to the club in December of the following season, joining for the remainder of the campaign.
