Ginn Racing development driver and motocross champion Ricky Carmichael made his stock car debut Saturday night in a super late model race at Columbia Motorsports Park. Under the watchful eye of Nextel Cup point leader Mark Martin, Carmichael finished third in his heat race. In the main feature, he overcame a second lap incident, but on Lap 7 of 25 his right-front tire went flat, sending his No. 4 Monster Energy Chevy into the wall and a premature exit from the race. Fellow Ginn development driver Matt Martin finished fourth in his heat and seventh overall in the feature. Carmichael's next two scheduled late model races will be April 21 and April 28 at New Smyrna Speedway in New Smyrna Beach, Fla. He is expected to compete in a total of 15 late model races this season. (Ginn PR) (03-25-07)
