Boisterous also recorded triumphs in the Red Smith and Knickerbocker in the final two starts of his four-year-old campaign in 2011. The Shug McGaughey-trained son of Distorted Humor captured the Grade 3 Fort Marcy earlier this season and placed in both Grade 1 Manhattan and Grade 3 Arlington Handicap before launching his present winning skein. He will break from post 2 with Jose Lezcano.

The main rival for Boisterous could be Guys Reward, winner of the Grade 2 Firecracker Handicap and Opening Verse on the Matt Winn turf course in the spring. By Grand Reward, the Dale Romans-trained five-year-old has recorded five of his seven career wins on the grass at Churchill Downs. He starts from post 7 under the spring meet's leading rider Corey Lanerie.
