It was a grim trifecta and a familiar result for Santa Anita Park: Three horses died in three days this past weekend at California’s best known and most scrutinized racetrack.

All three horses were euthanized, two after breaking their ankles in turf races and the third after colliding with another horse while training on dirt, racing officials said.

The latest spate of fatalities at the track began on Friday, when a 6-year-old gelding named Harliss broke an ankle in a turf race and was euthanized, according to racing officials.

Then on Saturday, a 5-year-old gelding named Uncontainable also broke an ankle in a claiming race on turf and was euthanized. The third death came on Sunday when Tikkun Olam, a 4-year-old gelding who had won $40,743 in nine races, collided with another horse while training on dirt. The nature of the horse’s injuries was not immediately clear.
