MIAMI - Gin Rummy Champ ($10.60) followed Running Bobcats's lead, finishing strongly along the rail to capture the $100,000 Calder Turf Sprint Handicap by two lengths over the slow-starting Sgt. Bert. Whatasoldier was third, while 2-1 favorite Justice for Auston finished a nonthreatening fourth after steadying in traffic on the turn. Gin Rummy Champ had been winless nearly two years before capturing an overnight stakes in his previous start. Cruz rode Gin Rummy Champ for trainer Frank Gomez.
