Key To My Heart (Ana O'Brien) supplied A I D A N O'Brien with a double and she became the third winner for the family on the evening when landing the Crowne Plaza Race & Stay Fillies Maiden at Dundalk.

The action began on the polytrack with an opening race win for True Blue Moon (Joseph and Donnacha O'Brien).

Then in the featured Patton Stakes A I D A N O'Brien's War Secretary prevailed under Seamie Heffernan.

Half-an-hour on and Key To My Heart, in first-time blinkers, made all to beat her stable companion Puppetshow by two and a half lengths.

"She did it well. We went a nice gallop and she kept going, she stays well," said the winning rider.

"The blinkers sharpened her up a bit as she's a bit laid back at home."

P.J. Smullen, rider of Assam (GB) trained by D. K. Weld, reported to the Clerk of Scales that his mount hung badly right throughout.
