Martin Truex Jr. probably should have won Sunday's Toyota Save Mart 350 at Sonoma, but engine troubles late in the race forced Truex to withdraw. Daytona 500 victor Kurt Busch was seventh for Ford.
Truex led the way early in the second stage but gave up the lead to pit during a debris caution on lap 39. He had a fast vehicle Sunday, but started the final 60-lap segment in 32nd position after a series of mishaps, including a spin, contact by A.J. With only few laps left, Bowyer founded himself in second place but knew he would not catch race victor Harvick due to having old tires. But Larson, the points leader, was never a factor and finished 26th.
Harvick was excited to score his first win at Sonoma after many years of trying. Brad Keselowski won this race in 2016 in dominating fashion. He now gets to attempt the road course in the #14 vehicle that Tony Stewart wheeled to victory here previous year.
AJ Allmendinger was fifth for JTG Daugherty Racing, and Danica Patrick was sixth for Stewart-Haas Racing in her best qualifying run of the season.

Sixteen laps after that lap-15 incident, Patrick was on the outside of a three-wide with Earnhardt and Kyle Larson.
Harvick and Childers ran what turned out to be a ideal strategy, pitting before the mandatory cautions for the Stages 1 and 2, gaining track position while sacrificing the bonus points. "And I had a glass of my wine before I made my lap". Erik Jones 26. Kyle Larson 27.
Stewart-Haas' co-owner Tony Stewart, who as a driver past year celebrated a thrilling victory by overtaking Denny Hamlin on the final lap, said this team victory is even more satisfying.
Two more Penske drivers will start in the second row after Josef Newgarden finished third and Simon Pagenaud came in fourth. "Go out there and take the challenge to them, as will Dixie, (and) see what happens".
