Purchased by Michael E. Pegram, who gave her to trainerBob Baffert for conditioning, Silverbulletday began her racing career at age two with an 11-length win. In her second start, she won the grade twoDebutante Stakes at Churchill Downs in June at six furlongs under jockey Gary Stevens. In late July, Stevens guided Silverbulletday to a win in the Grade III six and one half furlong Sorrento Stakes at Del Mar. After her first loss in the grade lll Del Mar Debutante, Baffert and Pegram mapped out a strategy of attempting to win the division by moving her tack for the rest of the year to Churchill Downs in Louisville, Kentucky. There Silverbulletday reeled off another three straight wins to finish her championship season. In early October, she won the grade two Alcibiades Stakes at Keeneland Race Course at a mile and one sixteenth. Then she clinched the division title with a win in the fall's grade oneBreeders' Cup Juvenile Fillies held at Churchill that year. In that race, she beat a very strong field of ten, including stakes winners Excellent Meeting and Three Ring, who finished second and third. Baffert then wheeled her back in three weeks to capture the grade threeGolden Rod Stakes at a mile and one sixteenth at Churchill. Silverbulletday's performances in 1998 earned her United States Champion 2-Yr-Old Filly honors.
1999 racing season
In 1999, Silverbulletday won five straight races, including such prestigious stakes as the Ashland Stakes, Kentucky Oaks, and Black-Eyed Susan Stakes. The Black-Eyed Susan is called by many the de facto second jewel of the filly Triple Crown and is run at a mile and one eighth at Pimlico Race Course in Baltimore, Maryland. In that race held on May 14, 1999, Silverbulletday beat a field of stakes winners, including Dreams Gallore and Vee Vee Star, who finished second and third respectively. Later that year, Silverbulletday was entered in the third of the American Classic Races, the Belmont Stakes. She held the lead through more than three-quarters of the race but the 1½ mile test proved too long for her and she finished seventh to winner Lemon Drop Kid. Silverbulletday came back to win over fillies in the Monmouth Oaks at Monmouth Park. At Saratoga Race Course, she won the 1¼-mile Alabama Stakes by nine lengths. She next won another Grade I event, the Gazelle Handicap, then ran second in the Beldame Stakes to Beautiful Pleasure. The heavy parimutuel betting favorite for the 1999 Breeders' Cup Distaff, Silverbulletday was in contention until the stretch drive but then faded and finished sixth to winner Beautiful Pleasure. Silverbulletday's performances in 1999 earned her United States Champion 3-Yr-Old Filly honors. In 2000, Silverbulletday returned to the track. Her best results were a win in the Doubledogdare Stakes at Keeneland Race Course and second-place finishes in the Grade IIFleur de Lis and Molly Pitcher Handicaps. Retired to broodmare duty having won fifteen races and banked more than $3 million, Silverbulletday has produced foals by prominent sires such as A.P. Indy and Storm Cat, but none to date have found significant racing success. Silverbulletday was a 2007 finalist on the balloting for induction in the U.S. Racing Hall of Fame. In 2009, she was inducted.
