With added motivation to honor a late friend, Kyle Larson seemed to have an extra gear Sunday at Bristol Motor Speedway.
The Hendrick Motorsports star led 411 of 500 laps in a victory that was dominant as it was emotional.
Larson, racing just days after the death of Jon Edwards, his former public relations representative, picked up his second Cup win of the season. It was his 31st Cup victory and third at Bristol.
''This one is definitely for Jon,'' Larson said. ''He is just a great guy, so we're going to miss him. Wish he was going to be here with us to celebrate, but I know he's celebrating with us in spirit. Just a flawless race at Bristol for the team. Really, really good car. That was a lot of fun.''
Denny Hamlin finished second in his 400th consecutive Cup start, falling one spot short in his bid for a third consecutive win. The Joe Gibbs Racing driver was gracious in defeat, noting Larson's victory came after a somber week that also included the deaths of longtime motorsports journalist Al Pearce and championship truck owner Shigeaki Hattori.
''You've got to give that team their due and Kyle his due,'' Hamlin said. ''Just a dominant performance. Looked like a pretty flawless day for him. It was all I had to try to keep up. Glad we were able to give him a little bit of a run, but this weekend we're all thinking about Jon Edwards and his family, Al Pearce, Shigeaki Hattori. We've lost a lot of great people in our sport over this past week. So our thoughts are with them.''
Ty Gibbs was third, followed by Chase Briscoe and Ryan Blaney, who led 48 laps but faded to fifth after pitting late and betting on catching a caution. The final 235 laps were run under the green flag in a race with only three yellow flags, the fewest at Bristol since August 1982.
Larson's No. 5 Chevrolet was one of several cars sporting a decal in the memory of Edwards, the Hendrick Motorsports director of communications whose death was confirmed in a Thursday statement from the team. The cause of death was not announced.
