In October of 1992 an 0 for 4 Minnesota bred maiden named Booly was entered in the Grade 3 Selima Stakes to be run on the Laurel turf course. The filly won as the longest price on the board. She was the third MN bred to win a graded stakes race.
I was corrected (see the comments) and must ammend the list of Minnesota bred graded stakes winners. Below are the four we know of. The Oracle submitted a blog entry on Super Abound last year. If the readers have additions, please chime in. Click the horse’s name to view the lifetime past performaces. Thanks to Daily Racing Form for providing the data.
