The daughter of Starspangledbanner was returning to Group company having won a Newmarket handicap back in July, but she took the step up in grade in her stride, fending off Mise En Rose to win by a hard-fought neck.
By winning this £60,000 prize, Spangled emulated her stable companion Realtra, who caused an upset in the race when landing the spoils twelve months ago.
This was the third win of the season for Spangled, who now boasts an impressive career record of five victories from ten starts.
Ridden by Andrea Atzeni, Spangled broke well from stall six, but she was restrained to sit midfield as the Mark Johnston-trained Lumiere bowled along at an even tempo.
The pace quickened heading down to the final quarter mile and virtually all the field held chances as the challengers fanned across the track.
Warm favourite Nemoralia was one of the first to come under pressure, but Spangled began to make sustained headway racing close to the stands-side rail.
Mise En Rose emerged from the centre to throw down a serious challenge, but Spangled was able to repel her effort, proving well on top passing the line.
Roger said: “We have always thought the world of Spangled – she is a big girl who weighs around 565 kilos!
"She has shown real guts to win and there is no rush to decide where to go next. This straight 7f, flat track and drying ground has suited her.
“Congratulations to the Cheveley Park team, whose season continues to go from strength to strength.”
