Warm Heart improved upon a runner-up spot at Leopardstown last month to make the breakthrough at the same venue for Aidan O'Brien.

The 13/8 favourite contested the 1m2f fillies maiden for three-year-olds plus and raced in second entering the home straight.

The leader, Feach Amach kicked off the bend and attempted to go for home, however, Wayne Lordan delivered his mount down the centre of the track and pair overwhelmed Feach Amach racing to the final furlong.

The new leader was kept up to her work as the closers came through and won by a length and a quarter. Aghadowey made good late progress to get up for second at 25/1 from another horse putting in late work in Shamida (2/1).

Stable representative Chris Armstrong said: “She’s a lovely filly and had two nice runs in maidens.

“Coming here, we thought she’d be very competitive stepping up in trip and Wayne gave her a lovely ride. It was a proper run maiden from start to finish.

“She is a filly with plenty of class and one to look forward to over that trip. She could get a bit further, but there's plenty of lovely races for her at a mile and a quarter.

“Hopefully she is a Stakes filly in the making.”
