Adahai is the clear standout in Saturday's $50,000 African Prince Stakes at Suffolk Downs, but the early leader of the 3-year-old class of Massachusetts-breds missed some training this summer and Saturday's start is just the second of his career.In his debut July 2, the gelding looked very much like a finished product, dashing to the lead in a 5 1/2-furlong maiden race and building momentum from there. He won by four lengths and earned a 61 Beyer Speed Figure - relatively gaudy for a young horse at Suffolk.
