Tamara, the winner of the Grade 1 Del Mar Debutante in 2023 whose career was repeatedly delayed by injuries or illnesses, has been retired, trainer Richard Mandella said Tuesday. Tamara was being prepared for a start in Sunday’s Grade 3 Las Flores Stakes at Santa Anita. An injury was detected after Tamara worked five furlongs in a fast 57.80 seconds on the infield training track at Santa Anita on Saturday. Mandella said post-workout X-rays were “clean, but she is off a little in her right front. “They’re planning to retire her, and I’m all for that,” he said. Tamara is by Bolt d’Oro and is out of the Hall of Fame mare Beholder, a four-time champion from 2012-16. Tamara raced for owner and breeder Spendthrift Farm and finished first in 3 of 5 starts in a career that began with high expectations in summer 2023. :: Santa Anita Classic Meet!
