Boss Sully powers clear in Siren Lure Stakes at Santa Anita

Boss Sully turned an eight-month layoff into a statement at Santa Anita Park, wiring the $100,000 Siren Lure Stakes in 1:08.42 and collecting the first stakes win, and first black-type win, of his career. The 6-year-old gelding did it with enough authority to make the race look controlled from the break, not messy luck in a soft spot.

Joel Rosario, back full-time at Santa Anita and winning on his first day back, put Boss Sully on the engine immediately and helped set an honest early tempo. Past The Wire reported opening fractions of 22.06 seconds for the quarter mile and 44.92 for the half, and Boss Sully kept rolling from there to beat Unconquerable Keen by 1 1/2 lengths. Artislas was third, just a head further back, while the rest of the 10-horse field never got close enough to change the shape of the finish.

The time did not threaten the Santa Anita turf sprint record of 1:06.60, but that is not the right standard for judging this performance. In a division where turf-sprint trips can swing wildly from race to race, Boss Sully’s value was in the way he handled pressure and still finished with authority. He was the lone California-bred in the field, and he went gate-to-wire on firm turf, which matters more than raw clock comparisons when the question is whether a horse is becoming a legitimate stakes player rather than simply beating one field.

That case gets stronger when the broader record is folded in. Daily Racing Form noted that Boss Sully had already returned from layoffs three times since August 2024 to win allowance races, and this latest comeback lifted him into a new class. Available profile figures place him at 17 starts with 6 wins and $469,392 in earnings, a resume that now reads like a seasoned older sprinter who has outgrown the allowance level.

Brian Koriner trained Boss Sully for Edward Rusty J. Brown, Alan P. Klein and Philip Lebherz, and the gelding is by Street Boss out of Eternally, bred by PT Syndicate #1 LLC. For a horse who had been useful but still unproven in stakes company, the Siren Lure was more than a tidy win. It suggested a mature turf sprinter who belongs in the conversation for similar six-furlong stakes through the California circuit.
