Ryan Blaney drove the best lap in Friday’s final cup practice at Bristol Motor Speedway.
Blaney’s top lap was 20.172 seconds (89.223 mph) on the half-mile dirt track. He was followed by Alex Bowman (20.194 seconds / 89.135 mph), Denny Hamlin (20.228 seconds / 88.986 mph), Joey Logano (20.262 seconds / 88.836 mph) and rookie Chase Briscoe (20.313 seconds, 88.613 mph).
Kyle Larson will have to start at the back of his qualifying race on Saturday and Sunday because his team switched bikes on Friday. Larson was running off the track during the last practice session when he saw his engine temperatures rise. Larson had set the fastest average over 10, 15, 20, 25 and 30 consecutive laps in the session.
