John Oxx's highly-regarded Alanza earned a trip to Newmarket after finishing best in the pouring rain at Leopardstown to justify odds-on favouritism in the Ballycorus Stakes.
Sent off the 8-11 favourite under Johnny Murtagh, the daughter of Dubai Destination sat in fourth through the early stages, but it was clear she was travelling best turning into the straight.
Murtagh pushed her past long-time leader Marvada, approaching the furlong pole and she dug deep to score by a neck, in the process paying a compliment to her Curragh conqueror Emulous, who is bound for Royal Ascot next week.
Oxx said: “She won nicely, as we hoped she would. She doesn't do a lot in front — I thought she was going to win two lengths but she was dossing in front. The ground has gone a bit for her, she wants good to firm — she loves that.
“I think we'll give her another shot at a Group One, in the Falmouth Stakes at Newmarket. She's good at seven furlongs but we'll give her one more shot at a mile.
“We decided against taking her over for the Windsor Forest as it's tough at Ascot.”
Oxx and Murtagh had earlier struck with Harasiya, also owned by the Aga Khan and who looks to have a very bright future, judged on her effort in the Irish Stallion Farms European Breeders Fund Fillies Maiden.
Oxx said: “That was a nice run and she's won nicely for her first time.
“It was a good effort too considering that she was slowly away. We liked her but you're never sure how green they'll be first time.
“She might be one to aim at the Moyglare — we'll run her in a month's time and then think about the Debutante in August — we'll see how she measures up in her prep race.
“She's by Pivotal and they like a little ease so we mightn't run her on good to firm.
“Her dam (Hazariya) was quite a good filly — she got a fracture in the Oaks — she stayed well.”
