Denny Hamlin wins weather-altered Clash, tempers flare behind him

Hamlin held off Kyle Busch, Ryan Blaney and the rest of the field on a two-lap shootout, following a late caution that was brought out by Ty Gibbs spinning. 

Gibbs had been leading the race until he got shuffled on the previous restart with just under 10 to go, which is when Hamlin took the lead.

Gibbs ended up in a post-race altercation with Joey Logano, who appeared to take exception to some aggressive racing by Gibbs. Also after the checkered flag, Ross Chastain doored Tyler Reddick following some contact on the final lap.

Hamlin led 58 of the 151 laps, second-most only behind Gibbs' 84. Hamlin started on the pole but slid back for much of the going, and in the closing stages, it seemed like the fight for the win was going to be between Gibbs and the hard-charging Logano.

That changed when Michael McDowell spun with 10 laps to go, which set up the race-deciding restart. Caution laps did not count during the event, so despite the late flurry of incidents, no green-flag action was missed out on.

In addition to being run Saturday night instead of Sunday, the race's scheduled qualifying format was altered as the heat races that were supposed to set the lineup were canceled. 

The starting grid was instead based on practice times, and several big names — most notably Christopher Bell and Chris Buescher — did not make the main event.

It's Hamlin's fourth-career Clash win, but the prior three were all when the race was still run at Daytona. That's where NASCAR will be the next time the cars hit the track, with the Daytona 500 set to run on Feb. 18 following a weekend off.
