MIAMI - Mico Margarita finally validated the high hopes trainer Steve Asmussen had for him as a 2-year-old when parlaying a perfect trip into an easy 4 1/2-length victory over longshot Red Rocket Express in Saturday’s $150,000 Carry Back Stakes at Calder. R Free Roll, the odds on favorite at 4-5 - and the lone filly in the Grade 3 stakes for 3-year-olds - finished a tiring fifth after engaging in a suicidal pace duel with Rockyshomerun.
