Gray makes debut This year's Champion Pony Rider Shane Gray makes his racecourse debut at Dundalk on Sunday, riding Rahya Cross for trainer Tommy Stack. Gray, from Dundalk and a brother to Galway Hurdle winning jockey Stephen Gray, has been based with Stack for the last three months and will partner Rahya Cross in the Group Discounts At Dundalk Stadium Race. Three year old Rahya Cross returns to race for Stack, having raced for the Co Tipperary trainer as a juvenile before moving to Jeremy Gask, in England, where she failed to win in three starts this year.
