O'Brien likely to prove key to cracking huge rollover at Navan

Chasers of a Super Pick Six rollover of €205,819 at Navan will be looking for a helping hand from Aidan O'Brien, who supplies the likely favourite in four of the races under consideration.

Reliance on Ballydoyle's fortunes is not without its potential pitfalls either, with the stable fielding two or three runners in each of the four events. Western Frontier looks the pick in an opening juvenile maiden (1.35) in which Michael O'Callaghan's once-raced Third Of March is nominated as back-up.

O'Brien's Dundalk winner No Never More and Fozzy Stack's debut Naas winner Eclipse Storm are suggested as the two against the field in the Listed juvenile race (2.05).
