With two furlongs to run, Fortune pulled Go Dutch out and asked him for his effort, His mount picked up well, going to the front an staying on strongly to win by a length and three quarters.
Roger said: "He was unsuited by the sticky ground at Newmarket and in hindsight that race was one of the hottest three-year-old handicaps of the year.
"He acts very well on down hill, turning tracks and loves fast ground. Hopefully we can have some fun with him this summer."
