Here are some things I'll be keeping an eye on.
Although I won't be betting all of the big three preps I will be watching them closely for clues.
I'm really only interested in the horses who finish in the money and/or within 3 lengths of the winners.
Atoned may be the only exception to that, given the fact that he's had so many seconds in a row I would forgive a poor effort as often horses that are stuck in rut like this throw in a bad performance before they get better.
Colonel John, Denis Of Cork, Atoned and Court Vision are really the only horses who I'm expecting to appear like possible Derby winners after these preps are over. War Pass is a maybe but with the questions surrounding his participation and the sloppy track I'm not what I'll make of his race even if he wins.
It'll take a big race done in the right way for any other horse to force his way into my thinking. Even though I'm backing Coast Guard to win the SA Derby I don't think he'll be a real legitimate Derby horse. Well at least not a Kentucky Derby horse, I certainly hope he's up to Santa Anita's version.
I will also be frowning upon horses that get passed in the last 1/8th of a mile.
For pretty much all of these horses I'm also going to prefer a new Beyer career top. None of them have run terribly high numbers as of yet so a regression in figs might suggest that they aren't fast enough.
