In the lead up to Sunday's GII Del Mar Derby, the betting public felt confident that Dutch Girl Holdings and Irving Ventures' Proletariat (Raging Bull {Fr}) would earn his first graded stakes score in the nine-furlong test for 3-year-olds. The public once again proved right as the gelding streaked home a wire-to-wire winner of Bust Out (Complexity).Sent immediately to the front by Kyle Frey, the bay rolled up front with longshot Pavlovian (Pavel) in hot pursuit through opening splits of :23.75 and :47.87. Still comfortably in front of his nearest rival Pavlovian turning for home, the Jeff Mullins trainee spurted clear, while having his robust advantage dwindle late, he had enough left in reserve to score by two lengths over the closing 7-1 chance Bust Out (Complexity).Jordi Bear (Ire) (St Mark's Basilica {Fr}) held on to beat Unrivaled Time (Not This Time).“Jeff and I talked before the race. He said use your 'Plan A', unless something comes up. Then go to 'Plan B', whatever that is,” said Frey. “It was 'Plan A' all the way today. This is a nice horse; he's very generous. And he's getting better.”A distant third behind Desert Gate sprinting five furlongs on the dirt at Santa Anita at two, Proletariat broke through with a win when trying a turf sprint at Del Mar in his next start last summer. He concluded his juvenile campaign finishing third in both the one-mile GIII Del Mar Juvenile Turf and Santa Anita's GIII Zuma Beach Stakes.Cutting back to six panels facing optional claiming company in Arcadia on May 15, the bay ran off to score by an easy 5 3/4-length margin in Del Mar's one-mile Oceanside Handicap on July 17.“It looked like a replay of the last race, just a little bit farther,” said Mullins, winning his second Del Mar Derby. “I could tell around the turn that Pavlovian wasn't going anywhere. He was already pushing and Kyle was still sitting.”“Kyle's done a lot of work getting the horse to slow down in the mornings. Teaching him how to rate and settle and relax and go when it was time.” Pedigree Notes: Sunday's Del Mar Derby victory earned Grade I-winner Raging Bull (Fr), who is represented by this first 3-year-olds in 2026, his first career group/graded score.Stakes-placed Kodiak West, who is also responsible for MGSP Sun Never Sets (Karakontie {Jpn}), produced a filly by Up to the Mark in 2025 and followed up with a filly by Constitution earlier this season. She was bred back to Kentucky Derby winner Mage.
