Assembly Hall, moving into contention on the far turn, rallied strongly through the stretch to earn a 2 1/4-length victory in the $75,000 Manitoba Derby at Assiniboia Downs on Monday.
Trained by Bryan Porter, who also is the co-owner of the Kentucky-bred in partnership with Dennis Goettsch, Assembly Hall was making his fifth career start and stakes debut in the 1 1/8-mile Manitoba Derby, an open race for 3-year-olds.
