Todd Gilliland dominated most of the race at Martinsville (Va.) Speedway and led the way heading into overtime, but Smith and Stewart Friesen made it a three-wide battle for the lead coming to the white flag of overtime.
Friesen turned Gilliland and also hit Zane Smith, which gave Friesen a flat tire and knocked him out of contention. NASCAR threw the caution for the wreck and Smith was locked in as the leader and declared the winner.
The win is Smith’s first of the season and couldn’t come at a better time. The victory locked him into next weekend’s Championship 4 at Phoenix and a chance to win a Trucks title.
Joining Smith in the title fight will be John Hunter Nemechek, Matt Crafton and Ben Rhodes.
“Man, I did not want Todd in front of me. He’s a good buddy of mine,” Smith said. “Honestly, I got shoved from behind by (Austin Hill). I ticked him off earlier in the race. That’s hard racing.
“Speed-wise, I don’t think we had anything for (Gilliland). I was worried if the race stayed green. I wasn’t losing hope just because you never know what’s going to happen. On the last restart, I got shoved into the corner and I was lucky I came out three-wide on the bottom.”
Smith said he was especially grateful to make the Championship 4 considering he doesn’t have any ride secured for the 2022 season.
“I’m looking for a job right now,” he said. “I have nothing.”
