Michael Greiner was the lone local racer competing in Daytona KartWeek By Cometic Gasket at Daytona International Speedway. The 15-year-old racer from nearby Palm Coast is racing this weekend injured. He broke his wrist last week while riding his bicycle in his neighborhood but is managing through the pain during four races this weekend. "Yesterday was a problem because I was running longer races," said Greiner, who drove the No. 88 kart. "I got a good night's sleep and it's OK today." On Saturday, he won the pole in Briggs Restricted Junior Lite but fell out after an accident and finished second in Briggs Restricted Junior Heavy. On Sunday, Greiner started on the pole and led every lap with exception of the last lap in a second-place finish in Briggs Junior Heavy. In Briggs Junior Lite, he came home in third. This weekend is Greiner's first karting event on the sprint track at DIS. He did compete in the Briggs four-cycle day on the 3.56-mile road course during December's karting events back in 2004. He has been racing karts for five years and this season could be his last in karts as he looks to make a move to the Formula Mazda Series. While many kart racers have dreams of racing NASCAR, Greiner prefers sports cars. "I've never really been a fan of circle tracks," Greiner said. "Road racing is challenging and more my type." Daytona KartWeek By Cometic Gasket has concluded. For more information on DIS Speedway events, call 1-800-PITSHOP or visit www.racetickets.com
