Mac Swiney was a tenacious winner of the Vertem Futurity Trophy at Doncaster.

Jim Bolger’s challenger, a Group 2 winner on soft ground at the Curragh in August, had since managed only eighth of 10 on a quicker surface over the same course and distance in the National Stakes.

But the son of New Approach again revelled in testing conditions as the rain set in on Town Moor, with the 12/1 shot challenging last under Kevin Manning to overhaul eventual third Baradar and hold off 6/4 favourite One Ruler in the final furlong, scoring by three-quarters of a length.
