Intricately took a thrilling renewal of the Moyglare Stud Stakes at the Curragh to give Joseph O'Brien his first Group One success as a trainer.

It was very much a family affair with his father, Aidan, saddling four of the other six runners in the seven-furlong contest and it was O'Brien senior's Hydrangea that attempted to make all under Padraig Beggy.

The pacesetter stuck to her guns when Donnacha O'Brien's mount laid down her challenge and with nothing between the pair as they did battle in the final furlong, Intricately got the nod by a short head for a 25-1 shock.

The winning trainer said: "It's unbelievable. She's very tough. She's been running well all year and Donnacha (brother) gave her an unbelievable ride today."

He went on: "This means the world to me. It's Donnacha's first Group One and my mum bred her. She's very tough and Donnacha was very strong on her.

"She's in the Fillies' Mile at Newmarket, and we'll see how she comes out of this. She doesn't have to run again this season.

"I can't believe she was 25-1 as she was only a length behind the second-favourite (Rhododendron) the last day.

"You probably get a bigger kick out of training winners than riding them, as a lot more work goes into it."
