In August of 1955 - there was a 4-year-old in Puerto Rico who was an undefeated 56-for-56 lifetime - he a winner of Puerto Rico's triple crown the year prior.
He finished his career with 73 wins from 77 lifetime starts - dying days after his final race.
Was he any good? I don't know.
Because I have no charts of his races and pp's for him and his competiton - what's most interesting about him - at least to me - is his pedigree.
His sire Thirteen - a son of a Travers winner - was an ok alw type horse in New York that came up through the claiming ranks.
His dam Flint Maid had a pretty decent pedigree - but was quite the bum while racing at ok tracks like Tropical (Calder) and Pimlico
No luck being able to so much as guess what kind of quality Camarero had - but his pedigree sure couldn't have been more American.
