A drop in trip worked wonders for Rainbow Moonstone as she opened her account at the second time of asking in the Rathasker Stud Irish EBF Fillies Maiden at Naas.

The Joseph O'Brien-trained filly had finished last of 16 on her debut at Gowran six days ago when running over a mile.

Shane Crosse produced the daughter of Holy Roman Emperor to lead over a furlong from home in today's six-furlong contest.

The 16/1 shot kept on well in the closing stages to beat Galtee Mist by three-parts-of-a-length.

“We thought she'd run very well in Gowran last week but she didn't stay,” said O'Brien.

“It was a mile on heavy ground, she travelled really well but just walked the last furlong.

“We dropped her back to six today and she's won. We didn't think she'd win but we thought she'd run well.

“I'm delighted to have my first winner for Mrs Nagle.

“I'd say there's not much left for her. I'd say she's not one for the all-weather and that's why we rushed her back a little bit.

“I'd imagine we'll go on the hunt for black-type next year.”

O'Brien also revealed that Shane Crosse is set to appeal the two-bay for careless riding picked up at Dundalk on Friday night:-

“I'd imagine he will. He has to sure as I thought it was really harsh. He is going to appeal I think.”
