FORT WORTH, Texas — Kyle Busch won for the first time this season to extend a 16-season streak while his penalized teammate missed a chance to secure a spot in the championship in the NASCAR playoff race at Texas that finished Wednesday, three days after it started.

Busch, the reigning Cup champion who is already out of contention for the title this year, finished 0.468 seconds ahead of Martin Truex Jr., his Joe Gibbs Racing teammate who had to go to the back of the field Sunday because of an illegal spoiler.

Truex, the 2017 champion and runner-up last season, also was docked 20 points because of that spoiler, a crucial penalty for the driver who was already below the cutoff line for the top four before that. A win would have taken care of that, but he couldn’t get past his teammate.

“Coming here we had a lot of confidence and we had a strong run,” Truex said. “This time of year, second is great, it’s just not good enough.”

There are spots for three other drivers to join Joey Logano for a run at the championship in the season finale Nov. 8 at Phoenix. The only race before then is Sunday at Martinsville, NASCAR’s oldest and shortest track where Truex won in June and last fall.

Busch led five times and was in front for 90 of the 334 laps at the 1 1/2-mile Texas track that was finally dried out after more than three days or misty conditions and drizzle combined with cool temperatures.
