Flighted:
I may be mistaken, but I seem to recall reading that Kipper Kelly began his
stud career as a teaser.
Going further back, to the early/mid 80s, Shug McGaughey, before hooking up
with the Phipps family, had a runner foaled by a stud named Smead, who
apparently was at one point or another a teaser.
Having a hard time verifying this, so if I am wrong I apologize to all of the
equine descendents and human connections of these fine stallions.
I am sure it would be interesting to statistically evaluate the produce of
unraced mares, I would not be surprised if this has been studied extensively.
You did not react to my comment about Mid-Atlantic contraction. Do you agree
that virtual year round racing in Delaware, Philly and Maryland is overkill?
