Jackpot won the first stakes start of his career by two lengths over Newfoundland in the $300,000 Gulfstream Park Handicap (gr. II) on Saturday. The Lady's Groom was another 1 3/4 lengths back for third in a field of six older horses. Jackpot, the 17-1 shot ridden by Joe Bravo, ran 1 1/4 miles in 2:02 4/5 and paid $36.20, $9.80 and $19.60. Newfoundland paid $3.80 and $9, while The Lady's Groom paid $20.40 to show. Bred and owned by Cynthia Phipps and trained by Shug McGaughey, Jackpot, a 6-year-old horse by Seeking the Gold, has won four of 16 starts with four second-place finishes. The victory raised his earnings to $288,915. "When he wanted to go I had no trouble getting him going," Bravos said. "Shug really did a great job with this horse."The Judge Sez Who ran fourth, followed by Indy Dancer and 7-10 favorite Seattle Fitz, who stalked the pace along the inside to the final turn and faded.
