JAMIE Piggott, son of the legendary Lester, finished well beaten on his first ride in public at Killarney.
The 19-year-old partnered Pivotal Rock for his boss Tommy Stack in the Killarney Grand Live Music Handicap over an extended mile at the County Kerry venue, with the six-year-old strongly backed and eventually sent off the 6-1 favourite.
Allowed to claim 10lb, the inexperienced rider was never too far off the pace aboard the market leader, but after becoming short of room in the straight, Pivotal Rock gradually faded and came home in midfield.
Victory went to 20-1 shot Measured Approval for trainer Pat Flynn and jockey Danny Grant.
Piggott, whose mount was seventh, said: "It was a good experience, the horse is good and honest but needed that bit extra today.
"I completed my A-levels in maths and three sciences before giving riding a go. I've only been riding properly for eight months. I've been riding out in Tommy Stack's and have been there full-time since before the winter - hopefully I can make a career of being a jockey now."
Piggott's sister and RTE sports presenter Tracy Piggott was present to see her brother, and Fozzy Stack, representing his father, said "Jamie did nothing wrong today and I was pleased with him. He happens to have an unfortunate surname as nobody will ever beat his father."
Grant said of the winner: "He ran a cracker at the Curragh but disappointed on his last two starts so we decided to change tactics with him today. We were worried about the ground but they went a good pace and he got into the race easily, everything worked out."
