Hit It A Bomb has won the Breeders' Cup Juvenile Turf to give Irish trainer Aidan O'Brien his third win in the race in the past five years.
Ridden towards the rear of the field by Ryan Moore for much of the mile (1600m) from barrier 14, the colt made up many lengths to sco re a narrow victory Airoforce and Birchwood.
"Obviously I'm delighted," O'Brien said.
"We were looking forward to bringing him here, but we were very worried when we saw stall 14.
"I'd say he's a classy miler and we will be looking at the Classics over that distance next year."
