Busch, who restarted second with 22 laps remaining, put the bump-and-run to Kyle Larson with six laps left for the win, his seventh in a Cup vehicle and 21st at Bristol across all three national series.
It was a little bit of a surprise that NASCAR got any of the race in Sunday amid the rain. By the time the race resumed Monday - after a series of brief sleet storms - the temperatures had dropped more than 20 degrees, hovering around 40. Seventy laps later, Wallace had fallen off the lead lap.
The weather led to a stop-start motion on Sunday and more delays on Monday that caused a skip in the regular rhythm for drivers and teams, even for race victor Busch. "I've been beaten by Kyle (Busch) about every time I race here, so that gets frustrating after a while". "The auto was really, really good and I was just hoping it would go green until the end". And yeah, as soon as we restarted there, I was extremely loose. "Fortunately, I was able to get away and he wasn't able to get to me".
Ryan Blaney led for 99 laps in the first stage, proving himself as one of the week's fastest cars, but he was caught up in a wreck entirely not of his doing and crashed out of the race.
Larson said he wasn't sure why his vehicle got loose late in the race, which allowed Busch to get by him.
"We've been talking about our cars performing better and driving better", said Johnson. A late-race caution for Brad Keselowski's flat left front tire set up a short 22-lap sprint for the finish.
"I just didn't have any grip", he said.
"I hate that I didn't win". Busch was in the lead, but Larson was able to catch him once things stayed green long enough.
"I feel like every time I race here I nearly get a win", Larson said of his second-place finish. Following in the top 10 were Jimmie Johnson, Denny Hamlin, Kyle Larson, Ricky Stenhouse Jr., Alex Bowman, Kevin Harvick, Austin Dillon and Darrell Wallace Jr. He had built a strong lead as he was looking to go to Victory Lane for the first time this season but Busch nudged him out of the way with five to go and held on for the win. We got a lot of respect today, passing the 18 on the outside, passing the 2 for the lead. After a disappointing finish last weekend at Martinsville, the rookie driver took the No. 43 to the lead for the first time since John Andretti in 2001. The Joe Gibbs Racing driver and 2015 series champion won his seventh career Cup race at Bristol, most among active drivers.
"The results stink right now", said Bayne.
