Izzi Top won at the highest level for the first time as she swept to an impressive victory in the Barclays Bank Ireland Pretty Polly Stakes at the Curragh.
Winner of both her races this season, at Newmarket and York, the John Gosden-trained daughter of Pivotal was sent off a 6-4 chance and settled in second place as the four runners travelled in single file behind Dermot Weld's challenger Sapphire.
Izzi Top quickly picked up the leader when asked the question by William Buick going to the furlong pole and though she didn't do a lot in front in the testing conditions, she had plenty left to hold the odds-on favourite by a length and a quarter.
David Simcock's I'm A Dreamer finished a close-up third, with the Aidan O'Brien-trained Up completing a four-runner field after the defection of Was, Maybe and Bible Belt.
Gosden said: "It's great to win this race because Pretty Polly was trained where I train now (Clarehaven Stables, Newmarket). She was a champion race-mare and won over a range of distances."
Of Izzi Top, he added: "William said she didn't like the ground, but not many like it that soft. A mile and a quarter is her trip and she tends to pull herself up when she hits the front - she got a bit idle there in the last furlong.
"We'll look at races like the Nassau Stakes at Goodwood and the Prix de l'Opera in France. We may think about the Breeders' Cup, too. The best work she has ever done has been in the last few weeks."
