They did.
It has been listed on NYRA site that the bet would run through October 6th. An extensive google search turned up nothing, not an article or press release as to why. I did uncover an article before last years Wood announcing it’s comeback.

The handle on the bet was abysmal even on big stakes Saturday’s it could not come close to the early pick 5 pool that is open to all. On any given day the early pick 5 pool would be 3 to 4 times the NYRA/NY outlets only wager.

Six months of Aqueduct are around the corner with 5 horse fields and 8 race cards 3&4 days a week through a couple of those months, making it not very appealing.
Of course there is not a NYRA press release pending that you can look forward to months of non-betable garbage.....

I get the marketing attempt to build NYRA bets by offering it to their own customers and to an extent it did grow their site. The bet just was unavailable
In too many markets to churn a big handle IMHO.
