The Margaret O'Sullivan trained Rebel Chief ridden by Robert Power ran out an easy 20 length winner of The Book Online Beginners Chase.

The son of Oscar was raced in behind the leaders and improved to lead from 4 out, strongly pressed 2 out but kept on well and was soon clear.

Margaret O'Sullivan said, "That's my fourth winner and my first ever chase winner. He's a lovely horse and needs loads of room at his fences so he loved it out there being raced on the outside. I'm moving to a new yard near Liscarroll point to point in two weeks time, which will have 28 stables. I have 19 in training at present most of which are all 4 year olds."
