After the race, driver Mike Simons related, "I remember driving this horse a couple of years ago and, if I recall, the track was very heavy that day and he had an outside post, so he didn't do too well.
"Jason (trainer Robinson) said he was very strong in winning his last start and can brush pretty good.
"He certainly did that tonight because he just had real good determination and didn't give up, even though he was out pretty much the entire last lap.
"He went a very courageous mile."
