He is one of nine drivers to have accomplished a Career Grand Slam, a feat which involves winning NASCAR's four most prestigious races: the Daytona 500, Aaron's 499, Coca-Cola 600, and Southern 500. The only other drivers to have accomplished this feat are Richard Petty, David Pearson, Bobby Allison, Darrell Waltrip, Dale Earnhardt, Jeff Gordon, Jimmie Johnson, and Kevin Harvick. Of the nine, Baker is the only driver never to have won a championship. He generally raced part-time, having only raced three full seasons, and co-owned his car from 1985 to 1989. He competed in two International Race of Champions series, IROC IV and IROC VII, and helped run the Buck Baker Racing School with his brother for a number of years.
