HALLANDALE  BEACH, Fla. - All three turf races in Friday’s Rainbow 6 sequence at Gulfstream Park will be taken off the grass and moved to the main course due to heavy overnight rains and a forecast for more rain later in the afternoon. There is a carryover of nearly $2 million going into Friday’s card, and the pool is expected to climb as high as $7 million or $8 million by the time it closes before the eighth race. There is a mandatory payout of the Rainbow 6 pool on Friday, closing day of the meet. {GULFSTREAM RAINBOW 6: Get PPs, watch the full card live] “In an effort to protect the public, we’ve made an early decision to move all the turf races to the main track,” explained Gulfstream president Tim Ritvo. “We did not want to face a situation where we got hit with more rain this afternoon, as forecasted, and had to take the races off the grass either right before or during the Rainbow 6 sequence. We understand the importance of today’s Rainbow 6 wager and wanted the public  to know as early as possibly exactly the situation they faced when it came to handicapping those races, and believe this decision was in the best interests of all our customers.” Ritvo said that the two earlier turf races on the card would remain on the grass for the time being in an effort to hold field sizes together, but acknowledged that with any additional rain, they too would have to be switched to the main track.
