Saturday is closing day. Per DRF Marty Mcgee:
"Before Saturday, when all gimmick wagers including the Single 6 will be subject to mandatory disbursements, an 11-race card will be run here Friday. First post for the last two days is 12:45 p.m. Eastern."
Why wouldn't Saturday be the mandatory payout day, instead of friday? That doesn't make sense.
