Super Espresso, a horse owned by celebrity chef Bobby Flay, swept around the pack and roared down the stretch to win the $100,000 Allaire DuPont Distaff Stakes at Pimlico.
Jockey Ramon Dominguez rode Super Espresso past Payton d'Oro near the wire to win by three-quarters of a length.
Super Espresso had struggled on turf in her last race.
"If you take out her last race on turf, she's been a steadily improving filly," trainer Todd Pletcher said. "She trained well leading up to this, so we're not shocked that she ran well."
Dominguez was concred that he would not reach Paton d'Oro, who had a clean trip, but Super Espresso had enough left at the end.
"She ran just the way Todd Expected," he said. "She's got a beautiful long stride on her and I just kept her together. They went quick enough early on where it was helpful, but she just continued coming. I don't feel like they were really collapsing in front of her. She was closing."
