Q: Passage: Roaring Riva began his racing career by winning a maiden race over five furlongs at Windsor Racecourse and then followed up by taking a minor event over six furlongs at the same track. In early July he was sent to York Racecourse to contest the Black Duck Stakes and finished second, beaten half a length by Nomination, a colt who went on to beat Green Desert in the Richmond Stakes. The colt was then sent to Ireland and moved up in class for the Group 1 Phoenix Stakes over six furlongs on soft ground at Phoenix Park Racecourse. Ridden by Ray Cochrane he started the 4/1 second favourite behind the highly regarded, but previously unraced Tate Gallery, with the best-fancied of the other eleven runners being the unbeaten filly Sherkraine, Devil's Run and Mr John. Roaring Riva was among the leaders from the start, went to the front two furlongs out and held off the challenge of the filly So Directed to win by three quarters of a length. Laing recalled that it was "quite a day. We had private planes, champagne, the lot!"
