Daily Racing Form called FIVE STAR DAY "one of Carson City's best sons" who "inherited his sire's brilliant speed." A six furlong specialist, FIVE STAR DAY's wins included the A. G. Vanderbilt H.-G2 at Saratoga in 1:08 2/5 after he set an opening quarter in :21 4/5. The final time was just two ticks off Saratoga's 132-year-old track record. His Phoenix Breeders' Cup-G3 win at Keeneland was in a blazing 1:07 4/5. Unraced at two, FIVE STAR DAY was first or second in 11 of his 16 starts from three to five. A four-time stakes winner, his placings included the King's Bishop-G1 and Kentucky Cup Sprint-G2.

By the top-class Mr. Prospector son Carson City, FIVE STAR DAY hails from a female family loaded with blacktype. In addition, his dam is a half-sister to leading sire Marquetry, whose progeny include two Eclipse Champion Sprinters and two Breeders' Cup Sprint-G1 winners.
