Kyle Larson posted the fastest lap in practice Friday at Auto Club Speedway at 189.071 mph. He was followed by Denny Hamlin (188.462 mph), Kevin Harvick (188.344), Jamie McMurray (187.940) and Joey Logano (187.588).
Defending race winner Jimmie Johnson had to go to a backup car after losing control in Turn 4 and sliding into the infield grass. The front of his car dug into the ground and was damaged. That was the only incident in the session involving cars. The session was stopped briefly for an owl on the track.
