MIAMI - Malibu Mint orchestrated the biggest upset in the six-year history of Calder's Summit of Speed program when she rallied to a convincing 3 3/4-length victory over Prospective Saint in Saturday's Grade 1, $500,000 . Dubai Escapade, the overwhelming 1-5 favorite, tired badly through the stretch and beat only one horse in a field of seven older fillies and mares.

Malibu Mint, a 4-year-old daughter of Malibu Moon, was fanned well wide leaving the final turn while

commencing her rally and easily ran down the struggling leaders to win going away. Prospective Saint was a clear second over the tiring Hot Storm.

Dubai Escapade raced perfectly placed, stalking pacesetter Hot Storm, but offered little response when set down by jockey Edgar Prado entering the stretch.

"Edgar said she just wasn't herself," said Dubai Escapade's trainer, Eoin Harty. "He said she made her middle move and at the top of the stretch she just flattened out. I can't blame the heat. It was this hot in New York."

Malibu Mint returned $49.20 to win but $79.40 to show since the heavy favorite finished off the board. The victory gave jockey Jose Arce his first graded stakes win.

"A lot of people might have been surprised, but I wasn't," said James Chapman, who trains Malibu Mint for owners Jane, Martha, and John Mulholland. "We've been dealing with feet problems on her and finally got that corrected. She grabbed a quarter when she lost her rider on Derby Day and probably came up a little short in her last start. But she's trained great since then."
