NASCAR Truck Series star laments opponent's 'scum racing' after spinning out on final lap

As the came around Turn 2, Heim spun out. Chandler Smith was able to maneuver around Riggs and took home the victory. Riggs finished in second place.

Heim delivered a message to Riggs after the race.

Needless to say, Heim was upset with how Riggs raced him and confronted him about it once everyone was back on pit road. Heim called Riggs' decision on the final lap "scum racing."

"I felt like he deserved to win over anyone else, not the 34 (Riggs). I got really loose into (Turn) 3. Just struggled being loose on the short runs, and he had an opportunity, and he wrecked me. Just disappointed."

Riggs defended his "strong move."

"If I have a reputation of going for wins, I'm not going to regret that at all," Riggs said. "You know, I feel like I came from short-track racing, last-lap battles, and feel like that's what this kind of racing is made for. I feel like it's not like we've seen at Martinsville in the past, and gotten upset. I feel like it was a strong move, and I thought it was going to pay off. 

"But sadly, didn't get the win."

Heim still leads the drivers standings with 450 points - 47 more than Smith. Riggs moved up to eighth in the standings.
