HALLANDALE BEACH, Fla. – Closing entries on a daily basis has proven to be a bit more of a challenge than one might expect during the early stages of the Gulfstream Park Championship meet. But the racing office certainly had no problems when it came to filling Saturday’s co-featured stakes races, the $125,000 Tropical Park Derby and $125,000 Tropical Park Oaks. The Derby lured a full field of 12, plus one also-eligible, the Oaks 12 and two others hoping to draw in. Both races are carded at 1 1/16 miles on turf with the added incentive of being the final opportunities for 3-year-olds to run against their own age group in stakes races here in 2025. Among the many trainers with multiple horses in the two stakes is Michael Trombetta, who will send out the undefeated Souper Forces as one of the favorites in the Tropical Park Derby and the pair of Souper Williwaw and Mischief in Motion about 90 minutes earlier in the Oaks. Souper Forces, a Live Oak homebred, is perfect in three starts while picking up plenty of frequent traveler miles to kick off his career, having won races at Presque Isle Downs, Colonial Downs, and most recently here when he rallied from near the rear of the field to a half-length victory as an 18-1 outsider in the Showing Up Stakes. He is poorly drawn on Saturday, however, and will break from post 12. :: Get Gulfstream Park Clocker Reports from Mike Welsch and the Clocker Team.

He just keeps showing up and running good,” Trombetta said. “It’s not the best of posts, and I know the turf has been a little biased [towards speed], but he’s a bit of a closer and with a big field there should be a little pace, so hopefully he can navigate his way through the traffic.” Trombetta’s Oaks fillies also are in top form to close their 3-year-old campaigns. Souper Williwaw has won her last two starts, both on turf, at Monmouth Park and Laurel Park. Mischief in Motion has captured two of her last four tries while also a game second returning locally in the Cellars Shiraz Stakes on Oct. 31. “We will be testing Souper Williwaw a little bit, but I think she belongs in there,” Trombetta said. “She had to have a throat procedure over the summer, it cost us some time, but she’s come back running real well. Mischief in Motion has had a great season. The main challenge in this race for her is the bigger field again.” Jaramillo heading west Mischief in Motion will be ridden again Saturday by jockey Emisael Jaramillo and is among the last few mounts he will accept here during the Championship meet before moving his tack to Santa Anita on a permanent basis later this month. Jaramillo will make the change despite having gotten off to a red-hot start during the opening two weeks of the current session. His nine victories put him atop the standings when racing resumes Thursday. “Emisael said he got a good opportunity, one he’s been waiting for, when he gave me the news,” explained Kevin Meyocks, Jaramillo’s agent for the past several seasons. “Saturday will be his last day here. He’ll be in Venezuela with some of the other local riders for a jockey challenge on Sunday before he heads out west.” Part of the impetus for Jaramillo’s decision to try his luck on the West Coast came from trainer Doug O’Neill. “I’m dear friends with jockey agent Tom Knust, who just lost his rider Antonio Fresu,” O’Neill said. “He was looking at a few options locally when I suggested he watch Jaramillo in Florida. I told him he can really ride. “I reached out to Emisael myself earlier this week, asked him if he’d consider coming out this way. He got back to me a couple of days later and said he’d like to try it. I, for one, think he’ll be a great addition to this colony and I’m excited to be able to use him when he arrives.” :: Play Gulfstream Park with confidence!

Gabaldon launched his career in high style with a victory in the Royal Palm Stakes and a second-place finish in the Windsor Castle Stakes at Royal Ascot during the spring of his 2-year-old season. The 3-year-old gelding has finished second in each of his last two local tries, the first of those outings on the grass, the most recent when making his debut over the Tapeta course four weeks ago. “I thought his last race was very good for the first time on the synthetic and going up against Rezasrolex, who is a monster on the Tapeta,” trainer Jose D’Angelo said. “He’s back on the turf Thursday, it’s just five furlongs, he’s got a good post, so I think he should be very tough to beat.” :: Want to learn more about handicapping and wagering?
