Friend of mine that works for the JC was in town and came to look at Rocket and confirmed what I thought. Rocket is Market Bluff.
His sire is Pine Bluff won the 92 Preakness (earned $2,255,884 on the track) and is half brother to the dam of Fusaichi Pegasus. Rocket seems to have several half brothers and sisters through his mum, but don't think any of them did anything to write home about.
Waiting to get his race record, he started 13 times and we figure he was a turf horse since most Pine Bluffs are. I think they have the same head (and color).
