Associated Press Darrell Wallace Jr. became the first black driver in a half-century to win on NASCAR’s national level, taking the Truck Series race Saturday at Martinsville Speedway at Martinsville, Va. Wendell Scott won in Jacksonville, Fla., in December 1963 in what is now known as the Sprint Cup Series, the highest of NASCAR’s three national levels. The 20-year-old Wallace, driving for Kyle Busch Motorsports, beat Jeb Burton into Turn 1 off a restart with five laps to go. Wallace was never below sixth place and led a race-high 96 laps but needed to survive a final restart. Wallace chose the inside line for the reset and quickly pulled away from Burton. Brendan Gaughan was second, followed by Burton. Championship leader Matt Crafton finished 17th and leads James Buescher by 51 points with three races remaining.
