Nine-year-old Undeterre gained a comfortable success under Neil Callan in the Field And Lawn Marquees Handicap.
The horse ran in the colours of former BHB chairman Peter Savill.
Callan sent Undeterred into the lead about a furlong from home, with the partnership coming home two-and-a-half-lengths clear of Time N Time Again, with Blackheath a similar distance away in third.
The jockey said: “I have only ridden Undeterred twice and I have won on him twice now.”
