Nurlan Bizakov's son of Oasis Dream bounced back from a disappointing run at Goodwood last time out to win well under Freddie Tylicki.
He was always in a handy position in the first-time visor, travelling strongly. He moved up to join the leader on turning for home and Freddie kicked for home with three furlongs to run.
First Dream drifted towards the stands rail but he was too strong and went on to win by a length and a half.
Roger said: "The change of head gear has helped First Dream he has won it nicely. He has improved all season and remains on an upward curve."
