In the Spinster on October 6, she battled with old rival Gorgeous and won by three lengths while setting a stakes record. Coming into the 1990 Breeders' Cup Distaff at Belmont Park on October 27, Bayakoa had six wins from nine starts, with two of those losses coming in open company against male horses. Despite her excellent record, she was only the second choice in the field to the brilliant three-year-old filly Go For Wand. Both front-runners by nature, the two battled for the lead for the first mile as if it was a match race. After they came off of the final turn and entered the last furlong, Go For Wand's leg shattered near the spot on the track where the great Ruffian is buried. Bayakoa continued on to the wire, and Go For Wand was euthanized. "I can hardly speak", said McNally. "I feel good for our mare, but I feel terrible because of what happened to Go For Wand."
