Prom Queen headlines Indiana Oaks after private sale to Delta Squad Racing

Prom Queen arrives at the Indiana Oaks as the horse to beat, but the private sale that changed her ownership only days before the race makes this more than a routine favorite’s assignment. The Grade 2 Gulfstream Park Oaks winner is the 9-5 morning-line choice for the $200,000 Grade 3 test at 1 1/16 miles Saturday at Horseshoe Indianapolis, and the new name on the papers adds a layer of uncertainty to a filly already headed into a stakes that anchors one of the track’s biggest summer cards.

Official records now list Delta Squad Racing, LLC, with Josh Isner, as the owner and Gary & Mary West Stables Inc. as the breeder. That matters because Prom Queen is not just another graded-stakes runner passing through a summer race. She has already won at the top of her division this year, and Brad Cox has continued to treat her like a filly with Grade 1 potential.

Prom Queen stamped that profile in the Gulfstream Park Oaks on March 28 at Gulfstream Park in Hallandale, Florida, when she won by 2 3/4 lengths in 1:44.40 and earned 100 Kentucky Oaks qualifying points. Equibase listed her 2026 line at five starts, two wins, one second and $278,380 in earnings as of July 7. She was competitive enough in the Kentucky Oaks, finishing fifth, before a distant fourth in the Acorn dulled the momentum just a bit.

Cox’s own comments after the Gulfstream Park Oaks explained why the barn still views her as more than a class horse in a soft spot. He said the longer 1 1/8-mile Kentucky Oaks distance would suit her and that she was more tactical than She Be Smooth, a telling line for a filly whose best weapon is not just talent but positioning. If that tactical speed shows up again, the ownership change may matter less on the track than it does on paper.

The race also has a second Cox runner in Nahla, who is not just filler in the field of six 3-year-old fillies. She was the only entrant with a prior win over the local track and has kept moving forward through her training at Indiana, giving Cox a legitimate backup threat if Prom Queen does not fire her best shot.

Mizumi, the 5-2 second choice, was expected to scratch for the Iowa Oaks, trimming one layer of competition from the field. That leaves Prom Queen in a race that sits inside Horseshoe Indianapolis’ 123-day season, which runs April 7 through November 13 and includes 47 stakes worth $4.95 million. For Cox, who has won the Indiana Derby three times since 2020 and owns only one prior Indiana Oaks victory with Shedaresthedevil, this is a chance to add a second Indiana Oaks line to a résumé already stacked with bigger-stage success.
