LEXINGTON, Ohio — As the laps dwindled, Chris Buescher's anxiety rose. The 21-year-old rookie was leading the NASCAR Nationwide Series race at Mid-Ohio Sports Car Course — gunning for his first victory — but was running out of fuel. "I was really focusing on taking deep breaths at that point," Buescher said about the final laps before he hung on to capture the Nationwide Children's Hospital 200 on Saturday for his first victory.
