3-year-old (barely) Stadtpark, running for just the second time, broke down and died in Thursday afternoon’s 4th race at Santa Anita. The young gelding was ridden by Ignacio Puglisi, trained by Paul Aguirre, owned by the Cuevas family et al., and bred by Kaleem Shah. According to Equibase, Stadtpark broke down “on his own.” This is horseracing.
