Andy Oliver's Run The Red Light attempts to halt the Aidan O'Brien domination of the Debutante Stakes at the Curragh.

O'Brien is searching for his 10th victory in this Group Two event, and his winner last year was this week's Yorkshire Oaks heroine Tapestry. Qualify appears to head the Ballydoyle trio ahead of I Am Beautiful and Toogoodtobetrue

Run The Red Light won a minor event over course and distance a fortnight ago, and Oliver said: "It is the natural progression for her to go for this race.

"I'm not really worried about the ground. She was declared on good ground before and then the rain came and she handled it well, so the ground isn't issue. If there was rain I know it won't inconvenience me.

"She won three and a quarter lengths the last day and that is traditionally quite a good race. There were a couple of fillies in it expected to go well and they all finished behind her.

"We don't really have anywhere else to go. There is a nursery at Gowran, but I think she is entitled to take her chance here and how she performs, time will tell.

"Whatever happens we would expect her to be a better filly in time. She has the physical attributes to improve with age. She is not going to have too many runs this year, maybe one or two more." Beach Belle drops down in class after losing her unbeaten record with a good fourth in the Phoenix Stakes, while Roger Varian's British raider Tigrilla and unbeaten Jim Bolger and Godolphin filly Lucida add further strength to the line-up.

Bolger said: "Lucida is in very good form and I was very pleased with her effort at Naas. I am expecting a very good run from her."
