Champion racemare Riboletta will return to training after falling victim to the mysterious mare reproductive loss syndrome that has devastated Kentucky. Riboletta will return to trainer Eduardo Inda's barn in California.The Daily Racing Form is reporting that Riboletta, who was boarded at the Taylor family's Taylor Made Farm near Nicholasville Ky., was found to have aborted a Forestry foal about two weeks ago. Forestry, a Storm Cat horse whom Aaron and Marie Jones also raced, stands at Taylor Made for $50,000. Riboletta, like many of the mares affected by the syndrome, was bred in February.The Form also reported that Drs. Larry Bramlage in Kentucky and Rick Arthur in California inspected and cleared Riboletta before the decision was made to return her to training.Before retiring last year, Riboletta won 7 of 11 starts and $1,384,860, including 6 major stakes - the Santa Margarita, Hawthorne, Vanity, Clement Hirsch, Ruffian, and Beldame.Riboletta, who has not raced since finishing seventh in the Breeders' Cup Distaff (gr. I), where she was the favorite, will return to California on Tuesday.
