Every week or so this summer, Sophie Doyle has gotten in her car and driven the five hours from Arlington Park to Churchill Downs to breeze Street Band. She’s been in the saddle for the filly’s last nine starts, four of them wins, three of them third-place finishers. She first started getting on the filly last fall at Fair Grounds ... The Cotillion is Street Band’s first Grade 1 win. It’s also Sophie Doyle’s, and those hours in the filly’s saddle, during races and in the morning, may well have made the difference as the three-year-old took down even-money Guarana to win by 2 1/4 lengths, paying $17.40.
