the remainder of ard patrick's three-year-old campaign was disappointing as he failed to reproduce his epsom form. at royal ascot on 17 june he started 11/10 favourite for the thirteen furlong prince of wales's stakes in which he was required to concede weight to seven opponents. the duke of westminster's cupbearer, who was receiving thirteen pounds from the derby winner, won the race by three-quarters of a length from ard patrick, but was disqualified for "bumping and boring" the runner-up and placed last after an objection. ard patrick then developed leg trouble and was withdrawn from the eclipse stakes, which was won by cheers, a colt he had beaten at both epsom and ascot. he also missed the st leger his intended autumn target, which was won in his absence by sceptre. ard patrick returned on 1 october for the £10,000 jockey club stakes over one and three quarter miles at newmarket. carrying 131 pounds, he finished third to rising glass (119 pounds) and the four-year-old templemore (122).
