DEL MAR, Calif. - Jed Cohen, who died early Sunday after a lengthy illness, was in his sixth decade as a racehorse owner when he experienced an unprecedented level of success in 2017-18. In California and Kentucky, the family’s Red Baron’s Barn, in partnership with his son Tim’s Rancho Temescal, won 16 stakes with runners such as Itsinthepost, River Boyne, and Sharp Samurai. “It’s hard for me to believe,” Jed Cohen said in a 2018 interview with Daily Racing Form. “I’ve been at it a long time and I’ve never had this experience.” Cohen died at his home in Del Mar, Tim Cohen said. Jed Cohen was 89. Away from racing, Cohen had an investment advisory business in Beverly Hills. A native of Long Island, N.Y., Cohen attended races in his youth in New York with his father and moved to California in the late 1950s. Cohen launched his stable in the early 1960s. Through the years, Cohen used a variety of trainers, including Riley Cofer in the 1970s, and Darrell Vienna, who retired from training in 2016. With Vienna, Cohen raced Janet, who won two Grade 1 races in 2001 – the Ramona Handicap at Del Mar and the Yellow Ribbon Stakes at the Oak Tree at the Santa Anita meeting; and Suances, who won the Grade 2 San Francisco Breeders’ Cup Handicap at Bay Meadows in 2002. Red Baron’s Barn, with its familiar red silks, focused on European imports and domestic purchases in recent years and had a constant presence in Southern California racing. Tim Cohen took a more active role in the stable in recent years. Following Vienna’s retirement, the stable has kept horses with a variety of trainers, notably Mark Glatt and Jeff Mullins. Glatt trained Sharp Samurai, while Mullins had Itsinthepost and River Boyne. The stable bought a share in Dr. Schivel in the summer of 2020, days before the colt won the Grade 1 Del Mar Futurity. In 2021, Dr. Schivel won the Grade 1 Bing Crosby Stakes at Del Mar and was beaten a nose in the Breeders’ Cup Sprint at the same venue last November. Earlier this year, Dr. Schivel was third in the Group 1 Golden Shaheen Sprint in Dubai. In recent months, Red Baron’s Barn and Rancho Temescal won two turf stakes with Packs a Wahlop, who was eighth in the Breeders’ Cup Juvenile Turf at Keeneland on Nov. 4. On Thanksgiving, the 3-year-old filly Bellstreet Bridie, a $311,000 purchase at a horses-in-training sale in England in October, won her American debut in the Grade 3 Red Carpet Stakes at Del Mar. On Saturday at Del Mar, Percolate, a 3-year-old colt owned by Red Baron’s Barn and Rancho Temescal, won an allowance race on turf for trainer Michael McCarthy in the day’s final race. Cohen is survived by his wife, Roberta, and three children – Linda, Mark and Tim.
