Three allowance races won’t make things easy for bettors venturing to try the Rainbow 6 at Gulfstream Park on Sunday. With a mandatory payout and expected pool of $750,000, the wager is sure to attract its fair share of attention, but narrowing things down between classy contenders will be key. Starting with the fourth race on the Sunday card, the Rainbow 6 will feature two first-level turf allowances, a featured allowance on dirt in the eighth, two claiming races, and a maiden-claiming event to end the day. Each field includes at least seven horses. Race 4: A first-level allowance for 3-year-olds and up will present an immediate challenge for multi-race bettors. Sharpazano and Fuoco Vivo figure as outsiders in the 5 1/2-furlong turf sprint, but the remaining six runners all have winning chances. Giant Teddy, a 7-year-old gelding claimed in his last two starts, finished second behind the same rival in both races while switching from synthetic to turf. He earned matching 79 Beyer Speed Figures in those hard-fought efforts. :: Access the most trusted data and information in horse racing! DRF Past Performances and Picks are available now. Boat’s a Rockin has been out of sorts since Fernando Abreu claimed him in March, but the 9-year-old bounced back to finish fourth in a starter/optional-claiming race last time out. A Mid-Atlantic stakes contender for most of his career, he was claimed in three straight Gulfstream starts between January and March. Among the inexperienced contenders, Thought Control will try turf for the first time for Saffie Joseph Jr., having earned a 90 Beyer Speed Figure in his lone start on synthetic last year. Tap to Mischief will return from a nine-month layoff for Bruno Tessore after making three starts in New York for Bill Mott. Race 5: This $6,250 claiming race at a mile on dirt doesn’t get much easier. Speed Control is the one to beat coming off a 34-1 upset victory at this level last time out, but he lost his three prior starts by a combined 54 1/4 lengths. Prince David and Tut’s Revenge were distant seconds in their last starts, but they also are more consistent contenders. Race 6: Nearly every runner in the field of seven 3-year-olds and up is dropping from allowance to claiming company. Pure Class, once a consistent allowance contender, demonstrated the danger of that move last time out, when he dropped to this level and finished sixth by 10 lengths on April 12. Fiveeyesonskystars, a 5-year-old trained by Roderick Rodriguez, ran at long odds for most of his 2025 campaign, notably pulling off a 15-1 upset in an allowance last summer. He will run with a $35,000 tag in his first start since October. Race 7: If a single can be squeezed out of the Rainbow 6 on Sunday, bettors may be forced to trust Thankfully to take care of business in the seventh, the other first-level turf allowance. The 4-year-old filly finished second with a 76 Beyer when she last ran this five-furlong distance on turf in February, giving her a slight edge for George Weaver. Royally Blue and The Dove Rules are among a slew of contenders who have shown comparable form in the past, muddying the waters for the likely favorite. Race 8: In the feature, a $71,000 allowance for 3-year-old fillies, several evenly matched contenders seem prepared to tackle the seven-furlong sprint. Winplaceandshow will offer obvious appeal coming off a statebred allowance win in March, but she won’t be alone. Canton, a sharp maiden winner for Joseph last year, has not had the chance to run on dirt since January. In her return to the track March 22, she ran on turf in the $100,000 Melody of Colors, finishing sixth. Caura is another seasoned contender shipping from Tampa Bay Downs for Carlos Narvaez, while the Jose D’Angelo-trained second-time starter Don’t Do It Lucy should garner attention as well. Race 9: The $35,000 maiden-claiming race at the end of the card is sure to sabotage many surviving tickets, as there is no clear standout in the field of nine fillies and mares. Ignis Cor and Pearl of Pearl both have proven form on turf, but Relentless Lady will try it for the first time and leads a group looking for improvement on the surface. The Sunday forecast around Gulfstream Park calls for cloudy skies, suggesting that the turf-heavy Rainbow 6 should remain largely unchanged. :: Want to learn more about handicapping and wagering?
