Somewhat quietly, David Jacobson’s training comeback has been a success. Jacobson retired in 2018 but returned in 2022, winning a dozen races last year. During 2023, Jacobson has 71 winners from 385 starters, with his stable closing in on $4 million in earnings, numbers that can get a bump Sunday when Jacobson sends out Quality Chic in the featured seventh race at Aqueduct.
