Based on his racing career, Orb's sire Malibu Moon didn't achieve very much on the track:
Here are Malibu Moon's pp's:

However, sons of A. P. Indy simply are never as good going short. Malibu Moon ran two nice figures at distances of 4.5 furlongs and 5 furlongs in his only two career starts, and that demonstrates special potential.
No offspring of A. P. Indy has ever won a race at Saratoga at the distances of six furlongs or less. Dreaming of Julia (out of the sensationally fast Rick Violette front-running sprinter Dream Rush) had a chance to break that last season at Saratoga... but Pletcher debuted the A. P. Indy daughter at 6.5 furlongs instead of 6 furlongs...and the streak still lives on.
By the way, here are the lifetime past performances of the 2nd and 3rd place finishers in Malibu Moon's lone career win:
* Family Hero, 2nd to Malibu Moon in his career debut, ended up with a 2-for-30 lifetime record. He was trounced in cheap claiming races at the end:

* Terror To Go, 3rd to Malibu Moon in his career debut, ran three abysmal races and was toast:

Malibu Moon might be the best stallion in thoroughbred racing right now ... but his racing career is a case of what might have been... primarily because of who his sire was. For a son of A. P. Indy, he sure did have proven sprint speed.
