The 10-year-old made virtually all in the Bedmax handicap chase, holding Whats Up Wood from George Bewley’s Hawick stable by three-and-a-quarter lengths.
“He has had a few issues since his last win, but he was down in the handicap and in a lower grade race,” said Harriet.
“He’ll now go for the veterans’ chase at Cartmel next month.”
Selkirk handler Stuart Coltherd was also in winning form at the course’s penultimate meeting, saddling Ash Park to win the Principal and Prosper conditional jockeys’ handicap hurdle race.
His teenage son, Sam, rode the 4-1 chance to victory, producing a strong finish to clinch victory by a length-and-a-quarter.
Coltherd, who also part-owns the gelding, was confident of his charge’s performance.
“I thought he would run well as he had been working well at home,” he explained.
“He´s a horse who doesn´t want the ground too soft and Sam was able to take a valuable 8lb off,” he added.
St Boswells owners Paul and Clare Rooney landed the feature Canada Life handicap chase with the Tom George-trained Always on the Run.

Hawick jockey Jamie Hamilton donned Trevor Hemmings colours to ride Mount Mews to victory in the opening division of the Ferguson Planning and Development bumper.
Malcolm Jefferson’s charge cruised home for an impressive 10-length success.
The concluding division also produced a convincing winner, when Thomas Campbell won by a 14-length margin for Lambourn trainer Nicky Henderson.
Six A Side, who had won his seventh point-to-point at Easingwold 10 days earlier, justified favouritism to head the Glendale Engineering novices’ hunters’ chase, where they went without Crazy Diamond.
He cruised home 11 lengths clear of Danehills Well, owned by Gavin Hamilton from Hawick, and ridden by his nephew, Tom.
There was no bid for the winner of the opening Tweedbank Office Dayout selling handicap chase – Generous Chief.
