Post-race, O'Brien reflected on a sedate opening pace that forced Moore into some early decisions.
"We thought we'd be sitting second and Dylan got the second position, so Ryan had to make a decision whether to sit second on Dylan's inside or pull back out of it so he wouldn't be boxed in," said O'Brien. "Ryan made the right decision."
The trainer was coy on future plans, with the Yorkshire Oaks next month a distinct possibility and the option of taking on the boys in the Prix de l'Arc de Triomphe at Longchamp now dismissed.
"She could do either of those two things," O'Brien said. "If she was going down the Arc trial route, she'd have to have a couple of easy weeks and obviously if she was going to York then she wouldn't have those couple easy weeks. I'd imagine we'd have a fair idea in the next week. Looking at her, she probably would love York."
Minnie Hauk trades generally around the 10/1 mark for the Arc in Paris later in the season and, winning rider Moore also remains fairly confident that she's saving something for herself in her races.
"She's a good filly and she's going to go on to better things as well," Moore told RTE after the race. "We're learning about her and she'll be better than this."
