Carlsbad, a winner of seven of 10 career starts and more than $435,000, suffered a fatal injury galloping out at the conclusion of a seven-furlong workout shortly after 9 a.m. Saturday morning at Santa Anita.
Trainer Jeff Mullins said Carlsbad suffered an open fracture of her right ankle on the clubhouse turn after completing her workout, which was timed in 1:26.80. The 3-year-old Arizona-bred filly was bred and owned by Dennis Weir. Carlsbad was expected to be favored in this Saturday's Grade 1 La Brea stakes, a seven-furlong sprint on opening day of the Santa Anita meet. Carlsbad was euthanized on the racetrack by veterinarian Melinda Blue.
