The Ashleigh and Michael Murphy team have a proven record of producing smart young mares’ from the point-to-point fields, with the likes of Lifeboat Mona and If You Say Run having gone on to pick up black type on the track for their new connections following points success for the pair, and in Costly Diamond, they would seem to have another exciting prospect. Making all, and setting a strong gallop in the process, the chestnut daughter of Mahler jumped with eye-catching assuredness, before beginning to stretch the field out along the back straight. What was particularly likeable, was that as the principals began to close in the home straight, including the twice-placed Subtle Quest from the Colin Bowe yard, she picked up once again and was always holding the runner-up to the line.
