Guaranteed confirmed himself a promising colt for Jim Bolger, as he landed the Group Three Eyrefield Stakes at Leopardstown.
Sovereign took the field along from Guaranteed
Into the home straight, the race developed into a three-horse race, with Guaranteed challenging and Masaff closing to the outside.
Sovereign dug deep, but between horses, Guaranteed and Kevin Manning had a bit more in hand and went on by a length.
Late on, Masaff closed, by Guranteed, a son of Teofilo, kept on to win cosily, with Sovereign third and a wide gap back to the rest.
