KANSAS CITY, Kan. — Matt Crafton knew he didn’t have the best truck Friday night.

Turns out all he needed was the most gas.

Crafton conserved just enough fuel while the leaders kept running out in the final laps to win the NASCAR Trucks Series race at Kansas Speedway, extending his lead in the points race by becoming the first two-time winner at the track.

“I said when we took the checkered flag, ‘We’d rather be lucky than good sometimes,”’ Crafton said. “You have to be close enough to sneak one out once in a while. I’ve lost them in things like this, so every once in a while, you steal one, I don’t feel too bad about it.”

All the trucks were forced to pit with 55 laps remaining, just on the upper end of the fuel window, when Ray Black Jr. blew his engine after a long green-flag run. It gave Crafton and the rest of the field a chance after 18-year-old Erik Jones had built a 12-second lead.

Jones raced right back to the front on the restart, once again stretching his lead to several seconds. But after leading 151 of 167 laps, his No. 4 Toyota ran out of fuel with five to go.
