It took Nemechek just five laps to take the lead for the first time and ended up leading 198 of the 250 laps, 1.518 seconds ahead of Sammy Smith to the win.
A late warning for a wreck involving Riley Herbst and Sam Mayer prompted a restart with 17 laps to go, but Nemechek pulled away quickly and was never seriously challenged for the lead.
This is Nemechek’s second this season and fourth of his career. Not only does he win a coveted Martinsville grandfather clock, but he also claims the $100,000 Dash4Cash program bonus.
“I can’t say enough about this whole team,” Nemechek said. “If you asked me yesterday if we had won I thought we were 10th place car in practice; I didn’t like us very much.
“I’m just grateful that the guys made the right adjustments and gave me a fast (car). Let’s party! Coy (Gibbs) – I wish he was here to celebrate with us. Second of the year!”
Cole Custer was third, Josh Berry overcame a late flat tire to finish fourth and Brandon Jones rounded out the top-five.
Completing the top 10 were Justin Allgaier, Daniel Hemric, Derek Kraus, Brett Moffitt and Chandler Smith.
Nemechek, Sammy Smith, Custer and Berry will be eligible for the $100,000 Dash4Cash bonus next weekend at Talladega (Alabama) Superspeedway.
