King of Rock’s run in the 5th at Gulfstream yesterday, as succinctly relayed by the chartwriter: “King of Rock suffered an injury to the left front leg and was euthanized.” For this to be reported at Gulfstream, which is notoriously tight-lipped about these things, King must have been euthanized where he lay. Which means that after an on-“field” death that all – fans, staff, racers, etc. – saw, not a one, apparently, had the slightest compunction about continuing with the day’s festivities (in this case, five more races.) Vile. King of Rock was four; ’twas his 12th time under the whip.
