This colt delivered a major Travers upset when he defeated the winners of the Kentucky Derby, Preakness, and Belmont in the ten-furlong race. It was the first time all three Triple Crown event winners had started in one race and were upset by another horse.
Who is the colt and in what year was the upset?
Also, name the winners of that year's Triple Crown races.

It's a year old but I never saw the Chinese version.

I don't know the answer to yours but I'll add one. Who was the last horse to beat Seabiscuit?
