With the Monster Energy All-Star Race set for Saturday night (6 p.m. ET, FS1) the 16 drivers already locked into the field got 90 minutes of afternoon practice under blazing hot skies at Charlotte Motor Speedway.
And when the dust settled, series points leader Kyle Larson was atop the speed charts, turning a best lap of 189.274 miles per hour in the No. 42 Chip Ganassi Racing Chevrolet
Second-fast was Kevin Harvick, who wheeled his Stewart-Haas Racing Ford to a fast lap of 189.095 mph. Brad Keselowski, Kyle Busch and Martin Truex Jr. completed the top five.
Given that the All-Star Race will be run at night, how the cars practiced today under 90-plus degree temperatures might not equate to how fast they are tomorrow night.
Still, it was an eventful session.
Larson and Kyle Busch both spun and kept their cars off the wall, but Denny Hamlin wasnt so lucky. Hamlin came out of the pits and on his first lap hit the wall, forcing his Joe Gibbs Racing team to bring out a backup car.
