4-year-old Rock Fall became the fourth racehorse killed at Keeneland in the last week when he, says the Paulick Report, “broke down in both front legs” while training this morning. PR carried this quote from owner Stonestreet Stables: “We are heartbroken to confirm our Rock Fall sustained a life ending training injury…” Both the “heartbroken” sentiment and the fact that Paulick even covered this at all can be entirely explained by the rousing success of this young “star” (back-to-back Grade 1 wins, 7 straight firsts overall, $750,000 earnings) and promise of riches yet to come (“one of the favorites for the upcoming Breeders’ Cup Sprint”).

This is horseracing.
