APPRENTICE jockey Mikey Sheehy completed a notable day’s work at Cork on Tuesday as the 5lb claimer completed his first double, and in the process also bagged a career highlight winner.

Sheehy began by steering Queenship (7/1, for the EuroLindy Syndicate) to win the Listed Navigation Stakes, for his employer Joseph O’Brien, which was a first at stakes level for the jockey.
