It may have taken a little longer than planned, but Deterministic, a 4-year-old colt trained by Christophe Clement, finally returned to the turf Saturday and set a course record at Aqueduct Racetrack to win the Grade 2 Fort Marcy Stakes. Cruising along on the front end in a field of five, jockey Kendrick Carmouche and the grass runner completed 1 1/8 miles on the outer turf course in 1:45.70. Deterministic finished the Fort Marcy four-tenths faster than Passive Management, who ran the distance in 1:46.10 to break his maiden as a 3-year-old in September 2024.  "Christophe had this horse right,” Carmouche said. “He ran a good race last time off the bench. This horse was really sharp. I just broke this horse good and let him do his thing. He brought me to the winner’s circle. I just had to guide him there. Every pole was a winning pole, from what I could’ve felt.” With Joel Rosario riding at Churchill Downs on Saturday, Carmouche took the mount on Deterministic and did not attempt to contain the colt in the second front-running trip of his career. He also took the early lead in his 2025 debut, a $150,000 allowance at Keeneland that was taken off the turf. “The only thing we were a touch worried about with Deterministic is it came off the turf last time at Keeneland and he had kind of a hard race coming off the bench like that,” assistant trainer Christophe Lorieul said in the winner’s circle. “But it set him up great. He went to the lead and never looked back. He was quite impressive.” :: Access the most trusted data and information in horse racing! DRF Past Performances and Picks are available now. Kay Army, a Chilean runner who finished third in his first start off a massive layoff, was the only one who stayed in touch with the leader early on, but no one applied serious pressure at any point. Through a modest half-mile in 47.93 seconds, Deterministic led by one length and extended that lead in the closing stages. Two-time Grade 1 winner Carson’s Run, another 4-year-old colt trained by Clement, made a show of running down his stablemate in the stretch, but after running without pressure for most of the race, Deterministic had plenty left at the end. After winning three Grade 3 races last year, he won his first Grade 2 event by 4 1/2 lengths over Carson's Run, paying $6.20 to win. Carmouche might not have known that he was on course-record pace aboard Deterministic, but he knew he was on a talented runner.  “I know how fast I’m going, but you never know if you are going to set a course record,” Carmouche said. “That don’t mean nothing to us, that means more for the breeders, more for the owners. I’m happy for the trainer, you know. I’m just pleased. I’m just grateful I got to sit on a horse like this. Hopefully we can keep going forward in the same direction.” The 1-2 finish in the Fort Marcy cements a big weekend in New York for the Clement barn, which also saddled Grade 3 Sheepshead Bay winner Bellezza yesterday. My Boy Prince wins Elusive Quality My Boy Prince, a 4-year-old gelding trained by Mark Casse, held off a slew of late challengers to win the $150,000 Elusive Quality. The Canadian-bred runner vied for the early lead through sharp early fractions and kicked away to win by a length. “He’s a lovely horse,” assistant trainer Shane Tripp said. “He worked really, really fast the other day away from the gate - probably a little quicker than I wanted to – but I figured he would give a good effort because every time you lead him over there, he usually gives you [one].” Speedy 8-year-old gelding Nothing Better broke sharpest of all in a race that was hotly contested from the very beginning. Jockey Jose Lezcano did very little to contain My Boy Prince, who settled right behind in second through an opening quarter-mile in 21.79 seconds. By the time the field turned for home, Casse’s gelding had already crashed the front and took a short lead into the stretch. “I was a little concerned with the fractions as [fast as] they were that he could stay, and he did,” Tripp said. “Jose [Lezcano] did a really nice job. After blowing through a half-mile in 44.36 seconds, all 10 horses were separated by less than three lengths as multiple closers began rallying in earnest. Five closing runners hit the wire in a photo finish for second, but none of them managed to chase down My Boy Prince, who spurted ahead to lead by 1 1/2 lengths in the stretch and hung on by a diminishing margin at the wire. He completed the six furlongs in 1:07.53 and paid $17.60 to win. Bold Journey, a graded stakes winner on dirt for trainer Bill Mott, entered the Elusive Quality with limited turf experience but responded well to the surface chance to win the five-way photo for second. Alogon, Twenty Six Black, Senbei, and Shards finished in order behind him, all separated by less than a quarter-length at the wire. :: Want to learn more about handicapping and wagering?
