LAST year’s Hennerty Laurels runner-up Tubbertelly Dubh begins his build up to the Curraheen classic when he contests the opening round of the Larry Dunne Open 525 at Shelbourne on Saturday night.

FOLLOWING the luxury of four qualifying from all first round heats, the pressure will begin in the Ladbrokes.com Irish Derby this evening at Shelbourne when it will be just three to survive to the third round.
