Mark Martin set the pace early in the first practice session at Auto Club Speedway with a speed of 182.924 mph and he maintained his top spot until the end of Friday's 1.5-hour practice.
Our View This practice is typically used to work on qualification setups and while Martin was fast nearly everywhere, he struggled a bit at Auto Club with an 18th-place time trial run in this race and a ninth in the fall. As one of only three drivers to break the 182 mph mark, he should better that this week.
