Denny Hamlin had the fastest average speed through the first two rounds of practice then backed it up by turning in the top speed (68.498 mph) during the third round, which was used to determine the starting lineup for the Clash.
Hamlin will start on the pole for the Clash, which was originally scheduled for Sunday night but moved to Saturday due to impending severe weather in the L.A. area.
Sharing the front row with Hamlin for the 150-lap preseason non-points race is Joey Logano (67.924 mph), who won the inaugural Clash at the Coliseum in 2022.
Last year’s Clash winner, JGR’s Martin Truex Jr., will line up 19th.
The drivers with the top 22 speeds made the field with the final position going to the team highest in owner points not already qualified. Reigning Cup champion Ryan Blaney claimed the final spot as he came in only 26th fastest overall.
Originally, heat races were going to be used to set the lineup and a last chance race held, but those were eliminated when NASCAR made the unprecedented decision to move the race up a day because of approaching bad weather.
Among the surprising drivers who did not advance to the main event were Hamlin’s JGR teammate, Christopher Bell, who was second-fastest through the first two rounds of practice, Daniel Suarez, Chris Buescher, Erik Jones and rookies Josh Berry and Zane Smith.
Through the first two rounds of eight-minute practice sessions, Hamlin posted the fastest average speed at 67.822 mph. He was followed by his JGR teammates Bell and Gibbs. Byron and Logano rounded out the top five.
In Group 1’s second round of practice, Austin Cindric spun off Turn 2 but did not damage his No. 2 Ford. His was the only incident in practice.
