NASCAR Auto Club Speedway results: Kyle Larson wins Auto Club 400, plus full finishing order

Kyle Larson passed Denny Hamlin with four laps remaining then kept the lead through an overtime restart to win the Auto Club 400 over Brad Keselowski and Clint Bowyer on Sunday at Auto Club Speedway.

Hamlin inherited the pole after Larson led a brigade of leaders down pit road to get four new tires under a caution brought out by rookie Corey LaJoie, who spun off Turn 2 with seven laps remaining. On the subsequent restart, Larson quickly passed Hamlin then maintained the lead on an overtime restart set up by a crash involving Roush Fenway Racing teammates Trevor Bayne and Ricky Stenhouse Jr.

The win was the second of Larson’s career and capped a dominating weekend where he won the pole Friday, took the checkered flag in Saturday’s Xfinity Series race, then led a race-high 110 of a possible 202 laps on Sunday. The 24-year-old Chip Ganassi Racing driver had finished second in the past three Monster Energy Cup Series races.

“This is just amazing,” Larson said. “We have been so good all year long, three seconds in a row. I’ve been watching all the TV like, ‘He doesn’t know how to win,’ but we knew how to win today, so that was good.”

Larson’s other Cup win occurred last August at Michigan International Speedway, a sister track to the 2-mile ACS oval located in Fontana, Calif. To win on Sunday, he had to withstand a series of late restarts that the fourth-year driver admitted tested his patience.

“I was staying as calm as I could be, but also frustrated at the same time,” Larson said. “It seems like every time I get to the lead at the end of one of these things, the caution comes out and I’ve got to fight people off on restarts.”

Keselowski had to overcome an opening lap chain-reaction fender-bender and a spin a few laps later to finish second. His car sustained considerable damage in both incidents, but his team made repairs and he was able to continue.

“We were tore all to hell,” Keselowski said. “Went all the way to back, just clawed all the way up to second.”

Martin Truex Jr., who led 73 laps, finished fourth despite staying out on old tires along with Hamlin. Joey Logano finished fifth, with Jamie McMurray sixth, rookie Daniel Suarez seventh, Kyle Busch eighth, Ryan Blaney ninth and Chase Elliott 10th.

Larson and Truex took turns dominating, with Larson winning the first stage and Truex the second. At one point, Truex held an 8.5-second lead, but his bid to win for the second time in three weeks came undone due to a slow final pit stop that cost him several positions and crew chief Cole Pearn’s later decision not to have Truex pit with the rest of the leaders with seven laps to go.

“We played offense all day and I was able to run first or second most of the day,” Truex said. “At the end, we had a disadvantage on tires and that’s just the way it goes sometimes. Sometimes you make the call and it’s right and sometimes your call is wrong. We made the wrong one today.”
