**Mason Hannagan Holds Off Williams in Knoxville Thriller** Mason Hannagan grabbed the pole and never looked back, but Ernie Williams Jr. made him work for every inch of Knoxville's red clay. Williams led for 17 laps in the middle stages and had the faster car through the middle portion of the feature, but Hannagan found his rhythm when it mattered most and closed it out on the final laps. Williams had a shot at the end but couldn't quite get the run needed to make a move stick. Trevor Royer's night was defined by a monster drive from 13th on the grid. He picked off eight cars and was running hard right to the checkered, finishing fifth and making a statement that he's got something for everyone here.
