AUBURN, Wash. – Exclusive Diva, a fast horse with fancy bloodlines, figures to be a strong favorite Sunday in the $50,000 Angie C Stakes at Emerald Downs. The daughter of Bernardini won her debut with ease last month and would seem to have a stakes victory or two in her immediate future. But she’ll have to contend with the less-heralded, but perhaps no-less talented, Royal Moses in the meeting’s first open stakes race for 2-year-old fillies.
