Scottish challenger
finished best to land the King
III Stakes at Royal
for Jim Goldie and Paul Mulrennan.
Successful in valuable handicaps at Musselburgh and York, the five-year-old was perhaps unfortunate not to finish closer than he did when fifth in the Temple Stakes at Haydock and was an 11-1 chance for this Group One debut.
Settled in midfield as the likes of Regional and Night Raider blazed a trail, American Affair was produced with his challenge inside the final two furlongs and found plenty for pressure to get the better of a protracted duel with Frost At Dawn by a neck.
