While Chastain was hard on himself, Trackhouse Racing owner Justin Marks defended his driver, who has won two Cup races this year.
“Honestly, I don’t think there’s a single thing Ross Chastain did wrong today, not a single thing,” Marks told NBC Sports. “This is a very, very competitive sport and you fight for every single inch.
“The thing is that he’s a newcomer in the top five and the established top-five guys don’t like there’s a newcomer there. I’m super, super proud of him. He’s very aggressive. That’s what is required in winning races and ultimately it’s going to get him to where he’s going to be NASCAR champion — his aggression matched with his talent.”
