A rare, weekday mandatory payout of the Rainbow 6 pool compelled by the end of the fiscal year in the state of Florida, will highlight Friday’s abbreviated eight-race program at Gulfstream Park. The sequence, which begins in the third race with a carryover of nearly $150,000, will include a pair of wide-open allowance events, the first for statebreds going a mile and 70 yards over the Tapeta surface, the second to be run at a mile on the main track.
