There is an all-time record carryover of $785,777 in Sunday's 50-cent pick five on the first five races.
The pool on Saturday reached $914,125. Going into the fifth race of the sequence, two horses were uncovered in the pick 5 - 50-1 Leroy Pegasus and 41-1 Diversionist.
Diversionist ($84.80) held off a late threat from 2-1 Satrapa to win by a head, creating the carryover.
A guess on how much money will be bet on Sunday is difficult, but a pool of new money of $3.5 million would not be a surprise.
The previous record carryover for a 50-cent pick five pool was $352,503 on Aug. 12, 2012. Bettors added $2.5 million to the pool at the next opportunity that season.
