After it potentially takes its toll on every major track on the East Coast this weekend, heavy rain may fall at Gulfstream Park on Sunday, complicating a mandatory-payout Rainbow 6 that already featured plenty of tricks and traps. Gulfstream Park officials are estimating the total pool could reach $3 million. Unlike most racing locales, forecasts in Florida are famously unreliable in warmer months, so the weather’s true impact on racing Sunday will remain difficult to judge until it plays its course. Bettors may eventually need to adjust their bets slightly for changes between turf and synthetic, but for now, the following analysis is being done with clear conditions in mind. Race 4: The first leg is a tricky $56,000 maiden special weight in which every horse seems to have a winning chance. Fleeting Free, one of two first-time starters in the field, is the sort of runner capable of blowing up a bet right out of the gate. The colt has plenty of pedigree for the turf and a nice work tab entering his debut. Deep Dusk returned from time off in April and ran sharply to finish fourth in his first turf sprint. Paco Lopez rode 4-year-old filly Speranzosa to a third-place finish last time out for trainer Christophe Clement, but the jockey will now switch to more obscure gelding Woodspoint, who will cut back to five furlongs after two disappointing starts this year. :: Access the most trusted data and information in horse racing!

Race 5: In a field of six going a mile and 70 yards in a statebred allowance, Hot Blooded is the only runner with a synthetic victory since the start of 2024. The 7-year-old gelding has been a hot claim lately and just left Mike Maker’s barn for a second time after a turf win at this level. He could represent a single opportunity for budget bettors, even if he isn’t the only runner with merit. Souper Watson hasn’t won since 2023 but ran some sharp races on synthetic last year, while 3-year-old colt Indecisiveness will make his debut on the surface after taking a wild, flailing shot in the Grade 1 Florida Derby last time out. Race 6: This $8,000 claiming race at one mile on dirt might require bettors to broaden their ticket. Lightly raced gelding Blast Radius probably has the most pop coming off a commanding 10 1/2-length win at a lower claiming condition for trainer Saffie Joseph Jr. Other contenders like Sixteen Cigarettes and Secret Lover may not have recent wins to match, but they have more seasoning at this level and have consistently finished in the money in recent starts. Mr Scatter took a massive drop in class last time out, ran terribly, and trainer Angel Quiroz retained him through a voided claim, adding one last puzzle to the mix. Race 7: This field of seven can quickly be narrowed down to four or five, but it gets difficult from there. Burnaway is switching back to synthetic and dropping in class after solid finishes behind stronger competition. It’s hard to come up with an excuse for a defeat at 4-5 odds two races back, however. Play Free Bird was claimed by Kent Sweezey last time out when she missed by a nose in her first try at this level. After three straight claims for this $12,500 price, Bomb Squad stepped up to a $17,500 condition last time out and struggled. She’s returning to her usual company here. Race 8: There’s a clear standout runner in this $57,000 allowance, as 4-year-old filly Mywifeknowsitall has gradually become a rock-solid synthetic sprinter over this surface. She has raced at this level in six straight races, winning three and just missing as runner-up in the other three. Those short losses are sure to scare some bettors looking for a single, but she’s as good as one can hope for. If anyone is going to give her problems, Coco Abarrio is making her 3-year-old debut after a flashy victory in July last year. The maturing runner may be able to make some noise for if she fires fresh off the layoff. Race 9: The Rainbow 6 on Sunday concludes with a $17,500 maiden-claiming race on turf that could trip up the last of the surviving bettors. El Muheet is the obvious horse to beat coming off a third-place finish in a $50,000 maiden-claiming race at Fair Grounds, but a longer glance at his past performances reveals a potential trap. The colt left trainer Brendan Walsh’s barn after that race and is now taking a massive drop in class without much justification. Maybe he simply overwhelms this field, but it could be more complicated than that. Accelerate Me will make his second career start after starting slow and steadily making up some places in his debut for Sweezey. Imperatus has raced at this level in three straight starts and has not finished worse than fourth in that span. :: Want to learn more about handicapping and wagering?
