SARATOGA SPRINGS, N.Y. – Katie Davis, who hit her head on the side of the gate prior to the start of Thursday’s fourth race, which required her to be removed from the track on a stretcher and taken to Albany Medical Center, was back in the saddle Friday where she rode 54-1 shot Luz de Guia to a third-place finish in the first race.  “I think it might have knocked some sense in me a little bit,” Davis joked after the race. “I felt strong riding him.”  Davis said after she got released from the hospital Thursday evening, her mother put poultice on the back of her head.  “The swelling went down,” Davis said. “I slept on an ice pack.”  Luz de Guia was Davis’s only mount Friday through Sunday so she felt it was important to ride. Davis’s next ride is Thursday at Aqueduct.  Davis has a new agent moving forward as former jockey Mike Luzzi has taken her book.  :: Want to learn more about handicapping and wagering?
