Blind Luck and Havre de Grace have emerged as the nation’s leading 3-year-old fillies, but lurking not far behind them, based on her close third-place finish in the Alabama Stakes, is Acting Happy, who continues to move forward toward the Nov. 5 Breeders’ Cup Ladies’ Classic, albeit with trainer Richard Dutrow Jr. keeping close tabs on her fickle constitution. “Right now, our intention is to run in the Ladies’ Classic,” Dutrow said Wednesday morning from his barn at Aqueduct. “The only thing is, sometimes she ties up when she ships. If she ships to Churchill Downs and ties up, she’s not going to run. She had a couple of off days when she first went up to Saratoga. When you move her around, sometimes she does that. If she does that in Kentucky, I’ll bring her back to Aqueduct. “She’s flying to Kentucky on the 31st. She’ll be on that plane if she keeps going the right way. She’s been breezing every six days, like clockwork.” Jose Lezcano has the mount. Dutrow has been working Acting Happy in blinkers and will run her in them for the first time in the Ladies’ Classic. “I thought about looking into it, and once we did, it seemed to pick up her training some,” Dutrow said. “She was more into finishing up the right way. In the Alabama, I thought she was looking at other horses.” Acting Happy has not raced since the Alabama. Prior to that, she was third in the Coaching Club American Oaks and won the Black-Eyed Susan Stakes. Based on form, and Dutrow’s ability to train horses up to peak performances off brief layoffs, Acting Happy would be a viable longshot in a Ladies’ Classic that is unlikely to number more than 10 entrants but will be long on quality. In addition to the top 3-year-old fillies, older runners Life At Ten, Persistently, and Unrivaled Belle are among those scheduled to be pre-entered next week.
