The Patrick Prendergast-trained Skitter Scatter arguably sets the standard on form after winning the Group Three Silver Flash Stakes at Leopardstown late last month.
Joseph O’Brien is represented by impressive Killarney scorer Iridessa and Vallambrosa, while Jessica Harrington runs course winner Chocolate Music.
