She Be Wild at 8-1 came with a powerful stretch run down the inside to score in the Breeders' Cup Juvenile Fillies at Santa Anita on Friday night.
Always A Princess took the field along during the early stages and she was still at the head of affairs two furlongs from home.
But as the 7-2 favourite Blind Luck, who had every chance, failed to quicken inside the closing stages it was Julien Leparoux who brought the Wayne Catalano-trained She Be Wild with a daring run up the inside.
They scored comfortably from Beautician (8-1), who ran well for second while Blind Luck filled third spot.
Catalano had previously won the race in 2006 with Dreaming Of Anna, and he said: "I was a little nervous when it looked like she might have been trapped a little bit.
"But we had a very good jockey with a lot of patience and I felt pretty comfortable when she got a run. She's not a very big filly so we didn't need much room."
Winning jockey Leparoux said: "I got a perfect race. I was on the rail all the way. I was hoping it would open up at the top, but I didn't really know. It did open up, a little bit, and that was good. That was all I needed."
Jockey Tyler Baze said of Blind Luck: "She got bumped pretty hard on the first turn. She got jostled around pretty good at that point. She tried real hard, like she always does. I put her in place to win but she just got outrun."
Blind Luck's trainer Jerry Hollendorfer meanwhile siad: "We got beat. No excuses. Coming for home, I thought we had enough horse to win."
