I'm not sure it's that as much as most of the field misjudging Authentic. I think no one thought he could get the distance, and he wasn't being pressured up front.

It doesn't matter. I'm truly heartbroken.

 I feel sad- I wanted Tiz to win so badly--- It looks like they will give him a breather and train up to the Breeder's Cup and that sounds like a good idea. I guess they all underestimated Authentic's ability to get

the distance, but he did and he ran a very nice race.

Well the jockey and the trainer are both saying surface played a big part in Tiz’s loss. 
I know you were routing for Tiz he ran great! 

The 4 legged boys came out of the Derby fine, the 2 legged ones didn’t fare as well.

What was the problem with the surface? Do you know?

The Derby was most watched sport since Super Bowl

I was crushed when Tiz did not get to the wire first! I adore the horse from the start of his career,with his noble presence, good looks,natural ability and coming from my home state for a change! I think on this day,Authentic was the best,but still believe that Tiz is more talented,,and either did not have enough time between races, and did not like the track! I  felt sorry for HonorAP who got stuck in the beginning and still managed to almost catch up and come in 4th. I 

look forward to seeing Tiz in the Breeders Cup after a deserved rest. 

Yep, I hope they stick by that decision for TTL (to NOT go to Preakness). Sounded like there was "some" consideration of it, but I hope they just train him up to the Breeders Cup. I'm New York-based also, and this Derby outcome was heartbreaking for me. I just turned off the TV after the finish and moved on to some other activity. 

Some big Beyer numbers on Derby Day!
