Ryan Moore enjoyed a successful first visit to Listowel with a double for Aidan O'Brien on day three of the Harvest Festival.Moore may have enjoyed big-race success across the globe during his glittering career in the saddle, but he had not previously been seen in competitive action at the County Kerry track.Moore arrived with a strong book of four rides and made an instant impact aboard Thrice in the opening Irish Stallion Farms EBF Maiden.Having finished a close third on his debut at the Curragh last month, Aidan O'Brien’s colt was a 1-4 favourite to open his account on his second start and rewarded odds-on backers with a comfortable four-length victory."He had a good run at the Curragh, he is still a bit babyish and was a little lost going around the bends," Moore said of the son of Wootton Bassett."Once he got balanced in the last furlong and a half, he stayed going well to the line."It is a flat track, a bit quick and a bit ridgy, but the horses seem to handle it well in general."They have a heated weighing room here, which is good!"Medici Venus shows bravery under Ryan Moore, battling her way through to contest the lead right on the line, getting the judges verdict from The Marty Party to win the MAC Hardware & Farm Supplies Irish EBF Rated Race for Aidan O'Brien!
