Oh geez, are you kidding me here?
Good Lord I'm so tired of the conspiracy theorists, truly. They really are a pain in the ass because they whine and cry wolf so many times that when something of a real crooked nature happens, people are desensitized to it.

They only have about a zillion horses. They screwed up, and hes being fined. The safeguard to this is the lip tatoo, which the identifier reads to insure who is who.
If anyone really thinks that Blasi wanted to run a ringer in a cheap race, they really need to get a clue about risk/reward. What does he gain? Well maybe possible embarassment and humiliation and a tongue lashing( I'm sure hes had plenty of all three). For a cheap claiming race? Does anyone truly feel that they were trying to put one over? LOL!! Were they gonna get the identifier in on it?
It happens, figure makers blow numbers, jockeys blow rides, grooms who are being paid very low wages bring over the wrong horse.
The guy got fined, and maybe it should have been a little higher, but since it was their first offense with this type of transgression(kenny mcpeek committed the same act this summer for the 2nd time in his career, and I'm sure noone ws more upset about it than kenny).
Newsflash, when a guy like Blasi has a bunch of horses in(and lake, Pletcher, Dutrow, whoever) they don't walk back to the barn after each race and walk out with the next runner. Its logistically impossible if you have a horse in back to back races. By the time the first race is over, and you talk to the jock, there is no way to sprint back to the barn and get the next one. You count on the asst or most often groom to lead the horse over.
Obviously there is a trainer responsibility issue and Blasi is ultimately responsible and was issued a fine.
