Outstrip's dam, Asi Siempre, from whom he inherited his grey colour, was a top class American racemare whose wins included the Spinster Stakes.
He started slowly but accelerated in the last quarter mile to take the lead a furlong from the finish and won by three lengths and a head from The Grey Gatsby and Cable Bay at odds of 13/8.
Barzalona settled the colt behind the leaders but was unable to make significant progress in the closing stages and finished third behind War Command and Cable Bay.
On his final appearance of the season, Outstrip was sent to California to contest the Grade I Breeders' Cup Juvenile Turf over one mile at Santa Anita Park.
Ridden by the American veteran Mike Smith (Barzalona was committed to ride for Godolphin in Japan) he came from well off the pace to win from Giovanni Boldini and Bobby's Kitten.
He was held up in the early stages and after struggling to obtain a clear run in the final quarter mile he was eased down and finished last of the fourteen runners behind Night of Thunder.
