Over the last five years, Brad Cox has trained 97 3-year-old turf winners and 445 3-year-old dirt winners. He’s won 111 sophomore dirt stakes during that span, 21 such turf stakes. But this summer, Cox packs a potent one-two punch with 3-year-old grass fillies. About a month after Fionn captured the Grade 1 Belmont Oaks Invitational, chasing down divisional leader Nitrogen, Destino D’Oro turned in an excellent performance winning the Pucker Up by almost four lengths on Aug. 3 at Ellis Park.
