Grasshopper ? ? ?

[jcs11204]

What has happened to him ? is it just a case of a horse losing it ? i thought he was sitting on a big year, and its been far from that. I just watched his replays of his saratoga races last year, and they are both about as good as it gets. Is this the perfect example of a horse not holding his form from 3-4, and the reasson why we see many of are good-great horses retired so early ?
