(AP) Horse owners and trainers in Massachusetts have enlisted the former head of the Maryland Jockey Club to help coordinate their effort to keep thoroughbred races going at Suffolk Downs, the Boston region’s lone remaining track. The New England Horsemen’s Benevolent and Protective Association said Tuesday that Louis Raffetto, who was president and chief operating officer of the Maryland Jockey Club, which runs the Pimlico and Laurel racetracks, will serve as its lead consultant. Raffetto oversaw racing operations at Suffolk Downs before coming to Maryland, where he headed the MJC from 2001 to 2007. He is president of YUP Racing, a Chinese-language horse racing betting website based in California. Sterling Suffolk Racecourse LLC, the Boston track’s current owners, is not seeking to operate live races in 2015 after gambling regulators rejected Mohegan Sun’s $1.1 billion casino project for the long-struggling track. The horsemen’s association wants to lease the track from Sterling Suffolk.
