Curve gets O´Sullivan off the mark Margaret O´Sullivan saddled her first winner when Indifference Curve readily justified good support in the two and three quarter miles Cashel Maiden Hurdle. Originally from Drimoleague in west Cork and renting a yard in Freshford, Co. Kilkenny, Ms O´Sullivan has held a licence for two months having previously been an assistant to Pat Fahy. The six-year-old son of Bob Back, backed down from 11/4 in the morning and sent off the 7/4 favourite, drew clear early in the straight under Andrew McNamara to beat Sang Bleu by a comfortable 12 lengths. ´I am delighted to train this winner for John McDonald who has been a great supporter of mine,´ said Ms O´Sullivan, who has 19 in training and hopes to soon move back to her native county to train near Liscarroll.
