That race more than likely would have had a jackpot Trifecta if it was not for this stupid partial Trifecta bet thing they have.

But someone got it.

The only "system" I see is heavy track, barrier 7, 1400 M
putting heavy emphasis on the heavy track and barrier 7,

fav was showing 1.50

What "system" gets these?
None that I know of.
