Tamarinbleu proved far too good for his 15 rivals when landing a notable success in the feature Langvale Homes Charleston Grange Perth Gold Cup at the Scottish venue.
David Pipe’s charge was always sitting prominently and travelling sweetly for 3lb claimer Andrew Glassonbury as Sue Smith’s Rare Society set a punishing gallop.
That rival was beginning to send out the distress signals as the principals swung for home for the final time and Glassonbury sensed his chance to unleash the 12-1 scorer.
After leading at the penultimate obstacle, Tamarinbleu measured the last well before sticking to his guns on the run to the line to lift the £30,000 handicap.
While he began to tire slightly inside the distance, the seven-year-old had five lengths in hand of runner-up and course specialist Kock De La Vesvre, who stayed on late for Liam Treadwell.
Rare Society stuck to his task gamely once passed to claim third spot, a further two lengths behind the front two.
