He's done enough
 

from a piece by Jay Leimbech:

A freak eye-injury ended that season and his string of five straight Horse of the Year titles. But Kelso was back in training the following February at age nine, when a young filly collided with him in a workout at Gulfstream, and X-rays revealed a hairline fracture of the right-front sesamoid. "I think the old boy has done enough," concluded trainer Hanford.

For once, it was true.

What a battler. Hanford said it, LOL. Good piece.
