The 1957-26 was a Grand National (now Nextel Cup) event held at Piedmont Interstate Fairgrounds on June 29, 1957. When Buck Baker and Speedy Thompson crashed in a four-car duel for the lead, Lee Petty emerged with the victory. When the race had to be called due to the track damage, Petty was declared the winner over Bill Amick. Baker, the eventual season champ, still finished 4th. Stats
