Last year’s Toyota/Save Mart 350 winner again took home the checkered flag. Although Truex didn’t enter as a favorite, he certainly drove like one after leading for 58 of the 90 laps.
The win also marked Truex’s third at the raceway.
Kyle Busch finished second and was close to catching the leader in the final laps but ultimately couldn’t find a way past Truex.
Ryan Blaney, Matt DiBenedetto and Denny Hamlin rounded out the top five.
William Byron ended up finishing 19th.
There were six total lead changes and two caution flags.
