Myboycharlie is a bay horse with no white markings bred in Ireland by Denis Noonan of the County Cork-based Cregg Stud.
[6] On 15 July, with Lordan again in the saddle, the colt was stepped up in class and distance for the Group 3 Anglesey Stakes over six and a half furlongs on heavy ground at the same track and started the 2/1 second favourite behind the Aidan O'Brien-trained South Dakota.
After being restrained in the early stages he went to the front approaching the final furlong and accelerated away from his opponents to win in "impressive" style by seven lengths from the filly Tuscan Evening.
On 19 August Myboycharlie was sent to France and moved up to Group 1 class for the Prix Morny over 1200 metres on soft ground at Deauville Racecourse in which he was ridden by Kieren Fallon.
After settling in sixth place he stayed on in the closing stages without ever looking likely to win and sustained his first defeat as he came home third behind New Approach and Rio de la Plata.
On 24 May he started 11/8 favourite for the Group 3 Greenlands Stakes over six furlongs at the Curragh but after leading for most of the way he was overtaken in the last quarter mile and finished fifth of the eight runners behind the four-year-old Astronomer Royal.
He began his North American campaign by finishing last when favourite for the Don Ciccio Stakes over five and a half furlongs at Hawthorne Race Course on 13 October.
