Weather was once again a factor in another race weekend, moving the Duck Commander 500 from Sunday to Monday. Biffle started fourth and was a factor inside the top five and top 10 for a majority of the race. Some teams gambled pitting for just two tires before the final green-white-checkered restart, while Biffle took four tires. Those who opted for two tires narrowly edged Biffle out of a top-five finish. Biffle capped off a solid extended Texas race weekend with a sixth-place finish in his No. 16 3M ESPE Dental Give Kids a Smile Ford Fusion.
“We just have to keep getting our cars better,” said Biffle. “We’re just not where the other guys are yet, so we’ve got to keep getting better. I feel better, but it seems every week we’ve got one car that is up there. We’ll keep working on it, but this is a step in the right direction for the No. 16.”
Biffle made it to the third and final round of knockout qualifying and narrowly missed a pole starting position, settling for a fourth-place starting spot in his No. 16 3M ESPE Dental Give Kids a Smile Ford. The race started with 10 caution laps due to all the rain the previous day and an older track surface that was difficult to dry. Once the green flag waved, Biffle maintained his track position with a Ford that was a little tight.

As the green-white-checkered finish unfolded, Biffle got pinned behind a car that gambled with two tires and was passed on the last lap, resulting in a sixth-place finish.
