The four-year-old bay gelding has won three of his four starts since arriving at Scott’s yard at Lindean, near Selkirk, in the autumn, most recently at Catterick in North Yorkshire a week ago yesterday, and is shouldering a 5lb penalty in the Weatherbys Global Stallions App Handicap over a mile and four furlongs at the East Lothian course.
Scott said: “He travelled a bit free but was given a great ride by Jason and is a happy and much-loved little horse.
“It was a fantastic day at Catterick as it was his first win on turf.”
Hart has been in the saddle for all three of Colinton’s wins for Scott to date, at Catterick last week and at Newcastle in February and March.
Hawick trainer Ewan Whillans also has horses lined up to race at Musselburgh today – Topkapi Star in the 2.20pm Miller Homes Handicap, with Rowan Scott riding; Act of Passion in the 4.35pm Join Racing TV Now Handicap, with Zak Wheatley as jockey; and Ramon di Loria in the 5.05pm Visit Racingtv.com Handicap, also ridden by Scott.
