[5] In Argentina, Blue Stripe was trained by Nicolas Martin Ferro and ridden by jockey Pavon Eduardo Ortega in all her races.
Blue Stripe began her career October 20, 2020 in the Premio Angel Comanche, a maiden event for three-year-old fillies at Hipódromo Argentino de Palermo, winning it by half a length over her owner's co-entry Serenata Huasteca in 1:37:98.
[7] Staying at San Isidro, Blue Stripe ran once more in the Group 1 Copa de Plata Roberto Vasquez Mansilla Internacional on December 19, 2020.
Staying along the rail as the field entered the straight, Blue Stripe managed to get a split and surged to challenge the eventual winner Elvas, but was found short and was overtaken close to home to finish third.
As the two fillies battled in the stretch, the three-year-old 84/1 longshot Soviet Catch mounted a furious drive on the outside in the final furlong, passing Mahagonny at the wire for second, but ran out of ground to collar Blue Stripe.
[13] Ridden by British Champion Jockey Lanfranco Dettori, Blue Stripe got shuffled shortly after the start, angled to the inside, steered off the rail backstretch, moved closer outside a rival, went three wide into the far turn, five wide into the stretch, failed to threaten around the bend, and weakened in the stretch run to finish seventh behind the Japanese-owned longshot Marche Lorraine.
The 11/10 favorite, Miss Bigly, took the lead with a five-wide sweep into the stretch at the eighth pole and looked home free in the 1+1⁄8-mile event.
Then Blue Stripe, ridden by Tyler Baze, surged even wider and went by Miss Bigly about 75 yards from the wire to win by a length in a time of 1:50.52.
She pulled a bit into the first turn, moved to the inside around that bend, tipped out and took aim two and then three wide into the stretch, and finished well but could not get to favorite Private Mission and was 3⁄4 lengths short.
However, Blue Stripe, the 5/1 third choice, ranged up outside of Shedaresthedevil, edged ahead turning for home, got clear of the favorite by the eighth pole, and scored by 1+3⁄4 lengths in 1:42.97.
After the 2022 Breeders' Cup Distaff, Blue Stripe was sold at the Fasig-Tipton November sale, where she was purchased for $4,000,000 by Emmanuel de Seroux of Narvick International for Grand Farm in Japan.
