Flashcard appeared to enjoy a return to a slower surface after opening his account for the season in emphatic fashion with victory in the Porsche Handicap at Ascot.
The son of Fast Company gained his first victory in more than 11 months when reversing form with his Newmarket conqueror Motakhayyel in the mile contest.
Travelling strongly throughout, the 3-1 favourite raced clear when asked for his maximum effort by Oisin Murphy, to cross the line four lengths clear of runner-up Prince Of Harts.
Winning trainer Andrew Balding said: “He had a tough winter and wasn’t himself in the spring, but he’s just come right now.
“He’s a talented horse, but I’d be reluctant to run him under a penalty. We’ll just take it on the chin, probably, and look at a handicap at York.
“He was a very talented two-year-old, and I’d been so far disappointed as I’d persuaded the owners to turn down a good offer in the winter.”
Emma Sayer rode her first winner of the season when her mother Dianne’s Redarna stayed on well, despite hanging badly left in the closing stages, to take the Longines Handicap for lady amateurs by two and a half lengths.
Redarna, also part-owned by her Cumbria trainer, took the spoils at 5-1 – with Ian Williams’ favourite Shady McCoy closest at the line.
There was consolation for Williams in the closing Plymouth Fruit Cup Handicap when his Western Duke posted a 14-1 success as jockey PJ McDonald topped and tailed the card with a double.
