MIAMI - A year ago Lost in the Fog cakewalked over a modest field of 3-year-olds in Calder's Carry Back Stakes, posting a career-best 116 Beyer Speed Figure while registering the sixth of his eight straight victories on the season. On Saturday, the reigning Eclipse Award-winning sprinter will find his competition quite a bit stiffer when he returns to Calder for the Grade 2, $500,000 Smile Sprint Handicap, a six-furlong dash that highlights the $2 million Summit of Speed.
