Hot Rod Charlie was disqualified from first in the Haskell and placed last.
In their ruling, the stewards said Prat "failed to make a reasonable effort to keep his horse from drifting in past the 1/8-mile pole, allowing his horse (to) cross in front of Midnight Bourbon, which resulted in Midnight Bourbon clipping heels with Hot Rod Charlie, causing Midnight Bourbon to stumble badly, unseating his rider."
Brad Pegram, Prat's agent, said Sunday morning that he had yet to discuss with his rider whether he will file an appeal.
In the Haskell, Prat, and the other jockeys, were not allowed to use their riding crops except as a safety measure due to restrictions put in place this year by the New Jersey Horse Racing Commission. Immediately after the race, Prat told BloodHorse he believed he could have prevented Hot Rod Charlie from drifting if he was able to provide left-handed encouragement with his crop.
Prat is the runaway leader in wins at the Del Mar meet with 20 prior to Sunday's card. Juan Hernandez and Abel Cedillo are tied for second with nine.
